Thank You for choosing TechTools for your development needs.
DigiView is a highly productive, thoroughly integrated tool with many in-depth features when
compared to other PC based Logic Analyzers. Each feature is deeply integrated and complete with
options that might not be immediately apparent. To benefit from all of DigiView's features we
suggest taking the time to briefly review our User's Guide. Some portions will cover obvious
features or those you may already be aware of however, you may find one of those 'must have'
features once you review this guide and start using the software.
§ Installing the Software 3
§ Installing the USB Drivers
§ USB Connection 4

Launching the software can be done by any of the standard methods (Start Menu, Desktop
Shortcut, selecting "Open" on a project file, etc). But the following sections provide much needed
information on what to do when the software launches and some basic usage that will help you get
the most benefit from our software such as using the Left or Right mouse buttons on many of our
buttons to activate opposite or symmetrical functions (Dual Function Buttons).
Some 'Must See' Basics
The Section "Menus, Tool Bars and Mouse Basics" covers some fundamental basics used
throughout the program such as using both Left and Right mouse clicks on many of our dual
function buttons.
See: Menus, Tool Bars and Mouse Basics

Some Layout and Window Placement
DigiView's software has a very customizable user interface to adapt to your needs. Docking,
Tabbing and aligning the various Feature Windows on the screen is covered in the Window
Arrangement section.

DigiView User's Guide
Getting a Project Started
After installing the software and connecting the DigiView hardware we suggest opening some
of the included project examples to experiment with, even if your Device Under Test is
configured differently than the example. This will help you get familiar with the flexibility of
DigiView's software.
The section "Project Selections" covers the initial startup screen and selecting one of our
example projects (that come complete with captured data).
See: Project Selections
1.1
22
Installing the Software
Chances are that you already know this part but ...
Install first, then connect
Always install our software before connecting the DigiView Logic Analyzer to the PC. The
Operating System can become confused if it sees the device connected before the proper
drivers have been installed.
Installing from CD ROM
Insert the CD ROM in your CD Drive. If the installation program does not auto-start, then go to
the CD ROM drive and Double-Click on the only executable file in the root directory of the CD.
If you are presented with a choice of products, select the DIGIVIEW software and follow the
prompts to complete the installation.
Installing from a WEB Download
If you downloaded the software from our web site, double-click on the file you downloaded to
launch the self-extracting install program. Follow the prompts to install the software.
(see also: Installing USB Drivers
1.2
3
)
Installing the USB Drivers
Our DigiView software and drivers are Authenticode signed.
If Windows reports that the publisher is unknown or that the software is not signed, then
the files are corrupt, infected or otherwise modified. Cancel the installation, delete the file
and download an authentic copy from our web site: http://www.tech-tools.com. The
Authenticode signature is timestamped to ensure the signature remains valid even if our Certificate
eventually expires. In other words, it will not 'time-out.' You will be able to re-install the software
and drivers, even if we go out of business or fail to renew our certificate.
Run the application installer BEFORE plugging in the hardware. It installs the
application software and pre-installs the drivers. You can accept the defaults or
modify to suite your needs.
Depending on your version of Windows and settings, the system might ask your permission when
© 2017 TechTools
Getting Started
4
installing the application and again when the drivers are installed.
When the installation is complete, plug the DigiView into a USB 3.0 SuperSpeed (supported by
DV5 series) or a USB 2.0 high-speed port. Preferably connect to a port directly mounted to the
motherboard at the rear of the computer. Current versions of Windows will see the hardware,
locate the pre-installed drivers and complete the driver installation.
NOTE: The very first time DigiView is connected, the Operating System will complete the driver
installation. If you receive the message "Driver Failed", then you may need to reboot the computer
in order for the OS to finish the installation it started when you connected DigiView.
This version is compatible with Win 7/8/10 (32bit and 64bit versions).
Driver Framework
If this is the first driver on your system to use the latest driver framework, Windows will take
additional steps to update the system. Newer frameworks coexist with older frameworks, ensuring
that existing drivers continue to operate as before. Unfortunately, this takes Windows several
minutes and requires a system reboot to complete. Note that this update occurs (if required) when
you connect DigiView to the PC – not during our application install.
1.3
USB Connection
Power:
§ DV3100, DV3109, DV3200, DV3209, DV3409, DV509, DV518:
Plug DigiView directly into a USB port on your PC or into a POWERED HUB. If using an external
hub, you should use one with its own power supply. Most bus-powered hubs can not provide
enough power to operate DigiView.
§ DV3400, DV3500:
Powered by an external power supply, so USB power is of no concern.
Speed:
§ DV3100, DV3109, DV3200, DV3209, DV3400, DV3409, DV3500:
You will experience better performance on a 2.0 port (High Speed @ 480 Mbps), but a 1.1 port is
sufficient.
§ DV509, DV518:
You will experience the best streaming performance on a 3.0 port (SuperSpeed @ 5 Gbps).
However, these units are compatible with 2.0 ports (High Speed @ 480 Mbps). You can still
stream at most sample rates using a 2.0 port unless the data rates are too high. If the streaming
terminates early the guaranteed minimum is still captured in the large Hardware buffer.
Connection Quality:
Preferably, use a high-speed USB port located directly on the motherboard at the rear of the
computer or a port anywhere on the computer case that utilizes a high quality cable internally. If
you use a different USB cable than the one provided with the unit, it should match the full rated
speed of the USB connection to prevent communication errors or loss of data.

Menus, Tool Bars and Mouse basics
This section covers some fundamental basics used throughout the program. Knowing this
information will be a tremendous help if you have never used our software or are updating to the
latest version.
Menus
Due to having numerous menus in the application, all menus have a Title Bar for identification.
Clicking anywhere in the title of a menu will dismiss it.
The Main Menu - Our application menu has changed to a single-button vertical menu located in
the upper-left corner of the main application window's top tool bar.
Local Menus - Each feature window has its own local menu on its tool bar. Some windows will
have an additional menu accessible by a Right-Click in the body of the window or other objects
that will display a menu when clicked.
Common Local Menu "Window" Item - Menu items on the local menu are options or functions
specific to the window's content. Local Menus also have a "Window" menu item with common
general options such as Tool Bar visibility and placement, Font properties, undocking and so
forth.
Tool Bars
The main application has two tool bars. One at the top and bottom of the application window.
see Top Tool Bar

Local Window Tool Bars - All docking windows have a configurable tool bar that auto-positions
itself at the top or left side of the window depending on the height to width ratio and where the
window is placed. This feature can be disabled and tool bar placement can be chosen by using
the local menu's Window option.
These tool bars can also be hidden by double clicking on any area not occupied by a button or
by using the small triangle in the upper-left corner. Repeating the process will re-open the tool
bar.

DigiView User's Guide
Mouse Basics
DigiView software uses the mouse position and mouse clicks to determine which window will
respond to mouse wheel movement and keyboard actions. It also responds to Left and Right
mouse clicks on the same item with different actions. The Middle mouse wheel (button) is also
utilized when clicked. When moving the mouse over a docked window or clicking on its border
or tool bar, its contents will appear to depress with a line drawn around it, meaning it will now
respond to any key strokes or mouse wheel movements.
Focus Example: If you position the mouse over a Waveform window, then press a cursor key,
the window will scroll (see Waveform View Mouse Functions 143 ).
Left/Right Click Example: A Left-Click on a Search Button 188 will search backwards from the
point clicked, while a Right-Click on a Search Button will search forward from the point clicked.
Most symmetrical or opposite functions utilize a Left and a Right click.
Middle Mouse Button Example: Clicking the middle mouse button in a Waveform View will
activate Quick Measurements 163 and the measurement starting point in Waveform Views.
1.4.1
Top Tool Bar
The tool bar at the top of the main application window provides fast access to the main menu,
several common project functions, analyzer control buttons and a hardware status message.
The Main Menu - Opens the vertical application menu. Access all major features, project
settings, search definitions, windows, configuration options, printing, saving images and
exporting from a single menu format.
Project Selections - Opens the Project Selections

to the project.
Delete a Signal - Opens a selection menu of all Signal Definitions currently in the project.
Selecting an item will remove it from the project and any other windows or configurations such
as Trigger configurations, Search definitions, Tables and List views.
Open a Feature Window - Select from several feature windows such as another Waveform
View 138 , a Measurements 161 window, an Auto Search 190 window, a Marker Time/Delta 171
window, a Status 135 window or create a Tabular View 138 for any Signal Definition in the project.
Search Manager - Opens the Search Manager 188 window or brings it into view if already open.
Manage Search Definitions 181 and perform manual searches 188 directly from this window.
Single or Split Waveform View - Two waveform views are always present in the center of the
main application window. This button toggles the visibility of the secondary Waveform View 138 .
Link and Unlink Waveforms - The Primary and Secondary Waveform views are permanently
assigned to Link Groups 1 and 2 respectively. Use this button to temporarily cross-link the two
groups so that all windows in both groups will stay time synchronized when any window of either
group scrolls. Normally this would occur only within the same Link Group 180 .
Analyzer Control and Status Message - Control buttons to activate the Analyzer's run modes
(Preview, Auto Run, Run Once... for details see Capturing Data 131 ). A Status Message and
trigger indicator are displayed immediately to the right of the Analyzer control buttons (for Details
see Hardware Status 132 ).

1.4.2
DigiView User's Guide
Bottom Tool Bar
The tool bar at the bottom of the main application window provides fast access to the Capture
History, the Analyzer status indicators and the project's assigned analyzer configuration.
The Project's assigned analyzer configuration - On the left of the bottom tool bar is displayed
the Analyzer model and mode the project is configured to use. To configure the project for a
different analyzer model or mode without starting from scratch, use the Clone Project option
(see Cloning a Project 26 ).
Capture History Buttons and Selection Bar - Buttons to access the Capture History menu,
Capture History Acquisition Options, Browsing, Bookmarking and deletion. The Bar Graph also
behaves similar to a scroll bar by providing a means to quickly load a capture and see it's
relative position in the history. For complete details see Capture History 133 .
Hardware Status - On the right of the bottom tool bar is the Hardware Status indicators. For
complete details see Hardware Status 132 .
1.5
Window Arrangement
DigiView makes extensive use of Docking and Tabbing to permit very flexible window arrangements.
All window settings, positions and sizes are saved along with the captured data anytime you save a
project file. If the Auto Save feature is enabled this will also occur when exiting the program or
opening a different project. These settings are all restored when you start the software or load an
existing '.DVDAT' file (see Project Operations 20 ).
The main application can be referred to as the Primary or Main window.
The feature windows created from the Feature Windows menu or from the 'Windows' item of the
main menu can be referred to as "secondary" or "dockable" windows.
To open a new window, select the "Feature Window" button (highlighted below) from the main tool
bar or select Menu-> Window-> New.
© 2017 TechTools
Getting Started
10
After opening a new window you can choose to move it anywhere on any monitor (multiple monitors
are supported) or dock it into one of the 6 docking areas of the primary window. You can also create
a Tabbed set of windows by docking it into a secondary window, even if that window is already
docked.

Docking Windows
Dock Sites
The main application form has 6 docking sites that surround the two permanent Waveform
Views that are in the center of the window; top, bottom, far top, far bottom, left and right. Any of
the secondary windows can be 'docked' to one of these sites by dragging the window over the
site. To prevent docking while dragging a window near a dock site, hold the Control key down
while dragging.
Docking sites are invisible until a window has been docked. After docking a window, the dock
displays a "handle" that can be used to size the dock or even close it. When all docked windows
are removed from a dock it will automatically close and become invisible again. The image
below was taken after docking a window in each site and then closing the dock so their
locations are visible. The visibility of a closed dock site depends on the chosen color theme.
The default theme (Slate) is used for all images in our documentation.

DigiView User's Guide
Docking a Window
When dragging a window over a docking site, a red rectangle appears to indicate that the dock
site is willing to accept the window. Releasing the mouse button at this point docks the window
to the main form at this spot.
Multiple windows can be docked into each of the dock sites in a variety of positions. As you drag
additional windows over a given dock site, a different red rectangle indicates where the window
would split into the dock site. You can drag it near the upper, top, lower, bottom, left or right
edges to control the placement.
If you drag the window inward a bit more, the rectangle may change slightly to indicate a
willingness to split the space occupied by an existing docked window rather than the dock site
itself. Dragging the window further towards the center of a docked window will cause the
rectangle to center in the window, which indicates the new window will "TAB" with the existing
window (see: Tabbing Windows 12 ). This flexibility allows you to dock the windows in virtually
any configuration.
Floating a Window
To 'undock' a window, simply drag it off of the dock site by its title bar or use the local menu
item of Window-> undock. Tabbed windows can be undocked by clicking on the up arrow in its
upper right corner, dragging its title bar or Right-Click on the tabs and select Undock. To
remove a window from a group of tabs, simply drag its tab away from the group or use the local
menu item of Window-> undock and it will become an independent window again. Any docking
window can be undocked or removed from a Tab group by using the window's local menu.
Docking Override
If you wish to drag a window near a dock site but do not want it to actually dock, hold down the
control key while dragging. This will disable the docking behavior, allowing you to drop the
window without docking it.
(also see: Tabbing Windows
12
).

Tabbing Windows
Secondary windows can be merged together by dragging one window over another. When you
drag any secondary window over another secondary window, a centered rectangle line
appears.
Dragging one window over another
Docking rectangle indicates the two
windows will 'Tab' together
This indicates that dropping the window at this point will merge them together into a single
window. Each original window appears on a TAB in the new window. Dropping additional
windows onto the tabbed window creates additional tabs.
© 2017 TechTools
13
DigiView User's Guide
Tabbed windows can be docked just like any normal window. Also, a secondary window can be
tabbed with a secondary window that has already been docked. Simply drag the window over
the center of the docked window until you see the centered red rectangle. This will TAB them
together at the docked location rather than dock the new window next to the existing window.
Floating a tabbed window
You float a tabbed window by dragging it off the dock site using its title bar, click on the up arrow
in its upper right corner or Right-Click on the tabs and select Undock. This will float the entire
tabbed window, keeping all of its tabs intact.
De-Tabbing a window
To remove a window from a tab, simple grab the tab and drag it,double-click on the tab or use
its local menu item of Window->undock. This extracts the window from the tabs and floats it.
When only two windows are tabbed together and one of these is removed, the tabbed window
will be disposed of and the remaining window will now occupy the position previously occupied
by the tabbed window. If the tabbed window had been docked, then the remaining window is
now docked in its place. See Docking Windows 10 for more information on docking.
Tab Window Options
After "Tabbing" windows together, several display options are available from a pop-up menu
that is accessible by Right-Clicking on any of the Tabs. For details on these options, see Tab
Window Options 14 .

Alignment Management
When not docked inside the main window, all windows have Alignment Management to assist
positioning when near the main application or each other. The frame of the window being moved will
become transparent for better visibility and highlight two of its edges (top or bottom and left or right)
that align with the closest neighboring window.
When within a few pixels of alignment to a neighboring window, it will assist placement by gently
resisting an overlap which effectively helps to 'snap' it into position. This method is more user
friendly than the strong "magnetic" placement used by other applications and is especially beneficial
when near multiple windows.
In the image below, the alignment of the left and top sides of the window being dragged is assisted
for placement next to the tabbed window on the left.
To override Alignment Management, hold the Control key while positioning a window.

To save a project, select the "Save Project" button from the main tool bar or select Menu->
Project-> Save Project. When a project is saved, the capture being view will be embedded into
the project file so it can be viewed the next time the project is opened, even if you manually
delete the history folder or move the project file to a different location. This also makes it simple
to share the project with a colleague since the history files and folder are not required to view the
capture.
Auto Save/Restore
The "Auto Save" and "Restore last Project" options are found in the Environment settings.
When both of these options are enabled, DigiView auto-saves the current data, settings and
state of the project when you exit the program (or load a different project) and auto-loads the
last opened project when you start the program. This allows you to pick-up where you left-off
the next time you start the software without having to save/restore. You can still save the project
manually anytime you need by selecting the "Save Project" button on the main tool bar.

Saving the Project with a new name or to a different directory
To save a project to a new location or with a different name, select Menu-> Project-> Save
Project As. When saving this way, the entire Capture History can be copied to the new location
and/or name as well.
See Also: Capture History

.
The Save Project As function will prompt you for a new name and location by opening a system
folder window. After making your selections, the DigiView software will ask permission to make
a copy of the capture history for the new project.
If you select yes when prompted, the entire capture history for the current project will be copied
to the new project's location and name. Since the Capture History is stored in a sub-folder using
the project's name, it is safe to create projects in the same directory. The "Copy History" prompt
also displays the amount of disk space being used by the history files and will copy as many files
as free space allows, leaving a safety margin.
The most recent captures are copied first (and kept in chronological order) in case you do not
have enough space available or if you decide to cancel before the entire history is copied.
Cloning a Project for a New Analyzer
You may wish to open a Project configured for a different Analyzer model than the one currently
attached to your PC and then want to capture new data with the new analyzer model without
having to recreate the project and all its settings. To do this, you can can clone the project by

This is the image that will display in the Template Selection window. It is created automatically
from the current project.
Note 1: Although the image does not completely reflect the project's position relative to all
monitors attached to the system, templates retain monitor specific information.
Note 2: Templates do not include Analyzer model, Signal definitions or anything that relies on
signal specific information (i.e. search definitions). If these items are needed, then use the
Clone Project 26 feature instead.
Managing Templates
You may want to go back and remove some of the custom templates you have created. To do
this select:

Configuration
The DigiView software is designed to make configuration an easy task and less time consuming
than most PC based analyzer systems. The easier it is to configure and understand your Capture
and Analysis tool, the easier it will be to achieve successful results.
To access the Project Configuration Options window, click the Project Settings button on the tool
bar (highlighted above) or select Menu-> Configure-> and the name of the configuration group
(Color Themes and Environment options are not project specific and are only available from this
menu).
After the hardware is connected to the PC, the first step of configuration is to attach the physical
channels to the circuit and create a Signal definition that uses those channels.
The first topic in this section covers the physical channel connections and cable color scheme.
The next section provides detailed information on defining trigger conditions and associating a
signal type with the physical channels. The remaining sections deal with user preferences.

Connecting the Data Lines
The DigiView data cable has either 18 data lines and 2 grounds or 9 data lines and 1 ground. The
18 channel cables are partitioned into 2 identical groups. Each group has a ground and 9 data
signals. The leads are color-coded. Black is ground, brown is the first data signal, red is the
second data signal and so on in standard resistor color-code order. Additional groups of signals
follow the same pattern.
The images below show the physical layout of the cable, channel numbers and color codes on
various models. This figure is available by clicking the "Cable Connector Pinout" button in Project
Configuration Options window or from any Signal Editor 37 window. This opens a non-modal
window so you can leave it open while you work if desired.
To access the Project Configuration Options window, click the Project Settings button on the tool
bar (highlighted above).

Configuration
34
After the Project Configuration Options window opens, click the "Cable Connector Pinout" button to
display the analyzer pin layout your project is configured for.
The data cable is made of high quality, extremely flexible wire and high quality connectors. It is
expensive, so please remember to pull on the connectors; not the wires.
The connectors are designed to mate to .025 square posts and can be side-stacked on 100mil
centers, making them ideal for direct connection to standard square post connectors. Additionally,
they mate firmly with the included micro-grabber hooks for connecting to IC leads.
DigiView Models DV3100, DV3109, DV3200, DV3209, DV3409, DV509 and DV518 are designed
for signals in the -20 to 20V range. DigiView Models DV3400 and DV3500 are designed for signals
in the -50 to 50V range. Standard overshoots and undershoots common to digital systems will not
harm it. The data lines have extra static protection circuits, current limits and impulse
suppression. However, mishandling could still damage them. Simply treat them like you (should)

treat your valuable one-of-a-kind target and DigiView will give you years of service.
3.2
Defining Signals and Triggers
The hardware will ignore any data lines that are not defined as part of a waveform or part of a
trigger. This prevents unused signals from eating up the sample buffer space, even if they are
connected to active signals. Signal definitions that are disabled will not be displayed, but may still
be captured if the definition includes a channel that is in use by another signal definition.
To access Signal and Trigger configuration options, click the Project Settings button on the tool
bar (highlighted above) then select the Signal Definitions tab or the Hardware Triggers tab.

3.2.1
Signals
Current DigiView hardware has either 9, 18 or 36 physical channels. However, we like to think in
terms of symbolic names representing individual signals (clock,ALE) or groups of signals
(DataBus, Address) rather than channel numbers(0,1,2..). We start by defining SIGNALS in
terms of CHANNELS. This is the only place we deal directly with physical channels. The
remainder of the software deals in terms of signal names rather than channel numbers. When we
define signals, we are mapping a signal NAME to one or more physical channels. This also
makes it possible to share the same physical channel with multiple signal definitions (see: Signal
Editors 37 ).
Adding Signals to the Project
To create a Signal, select the "Add Signal" button from Tool Bar (highlighted above, or use the
"Create Signal" button in the Project Configuration Options window).
Click on one of the selections to create a new signal. A new signal of the chosen type will be
created and it's property editor will appear. You can rename the signal, select the physical
channels to capture and set all associated options from the signal's editor. (For details on
signal options, see the section: Signal Editors 37 ) Use the Escape Key or the red close button
if you do not wish to add a signal.

Summary of the Project's Signals
Signals added to the project are listed in the Project Configuration Options window on the
Signal Definitions tab. To access the Project Configuration Options window, click the Project
Settings button on the tool bar (highlighted above) then select the "Signal Definitions" tab.
The main purpose of the lower section of this tab is to provide an overview of all current signal
definitions and their related channels. You can also Edit or Delete signals from this section,
determine each signal's type, its basic colors and its enabled status.The Project Signals
section is arranged in a grid with columns representing the physical channels and one row per
defined signal. Notice that the same channel can be assigned to multiple signal definitions. In
the image below, channel 8 has been assigned to several signal definitions (AD0-15, CODE,
address, RD-DATA, WT-DATA).
Channel 0 is in the farthest right column and the highest channel number is in the farthest left
column (as marked in the header.) A line appears every 4th channel (or nibble) for
clarification.
In addition to the color references at the top of the window, you can click on the 'Cable
Connector Pinout' button at the bottom of the window to see a physical layout of the attached
analyzer's channel connector with channel numbers, ground connection locations and the
color code of each channel.
Note: It is important to enable only channels that are actually being connected to your circuit.
The remaining, unconnected channels will be floating and will most likely pick up noise or
power line hum. If enabled, these transitions will get stored, wasting storage space. It is also
important to connect the black ground wires to your target's ground so that the analyzer and
the target have a common ground reference. It is recommended to place the ground
connections as close to the channel connections as possible.
Changing the Signal order When adding a large number of signal definitions, you may want to change some of their
positions to organize or group related signals. To change the display order, grab the small
handle in the left margin with your mouse and drag the definition to a new position.

Associated Channels All channels associated with this signal definition will be indicated in this display as a square
blue "dot". Channel 0 is in the farthest right column and the highest channel number is in the
farthest left column (as marked in the header.) Light lines appear every 4th channel and non
associated channels appear as a short dash. Also, colored squares at the top show each
channel's wire color. Notice that there are only 9 colors so the color sequence repeats using
resistor color code order (the color Black is used for ground connections - channels 0, 9, 18
and 27 are brown).
3.2.1.1
Signal Editors
DigiView provides several Signal type definitions which allow unique methods of interpreting and
displaying the raw data captured on the logic channels. Each Signal type has a unique editor with
relevant options for its type. From the editor you will also assign some of the physical logic
channels to be used for this new signal definition. (see: Connecting Data Lines 33 )
You may choose to repeat the use of some channels in multiple Signal definitions in order to
interpret the data differently and gain a perspective that is relative to your current point of interest.
This can be done easily by creating a new Signal using the definition with the properties you
require. Using the same channels in multiple definitions will not have any effect on the actual
capture, but can greatly increase your ability to analyze the data and present visual representation
to others.
© 2017 TechTools
Configuration
38
NOTE: The same channel can be assigned to as many signal definitions as you
need. For instance, if you want to capture the Read and Write cycles of an SPI
bus using separate signal definitions (instead of the combined read/write of the
SPI signal type), you can create 2 Synchronous Serial signals and assign the
same channel as the Clock for each definition.
Signal Selection
The signal selection can be expanded by adding Plug-ins which can be downloaded with the
software (as available) or created by using our free Plug-in Development Kit (downloadable from

To select a channel, click on the " - " below the proper color (and channel number) that
corresponds to the physical connection of the DigiView Cable (see: Connecting the Data
Lines 33 ). Channels that are selected for this signal will replace the " - " with a blue square
as shown above. The gray arrow beneath each channel color is an activity indicator that
displays the activity of the channel as compared to the activity of all the other channels
(relational, not real time).

If selected, the captured data for DATA will be inverted before decoding and displaying
(only affects this Signal Definition).
Show Delimiters
When selected, Delimiter fields will be visible in the output.
Show CRC
When selected, CRC fields will be visible in the output.
Show Control Bits

Bit Rate/Duration & Scale:
Specify a value for the Bit Rate or the Bit Duration, then select a scale for the value entered.
Scale selections include Nano seconds (ns), Micro seconds (us), Milli seconds (ms), Baud,
KiloBaud (KBaud) and MegaBaud (MBaud). Note that the value must be an integer (no
floating point.) To specify something with a decimal point, select the next lowest range and
enter a whole number. For example, 115.2 KBaud would be entered as 115200 Baud and
12.31us would be entered as 12310ns.
Sample Point (%bit)
Specifies where we should sample the data within each bit cell as a percentage of the bit
width. This defaults to mid-bit (50%) and can be adjusted to account for bus propagation
delays, transceiver delays, bandwidth limitations, etc. This roughly corresponds to the
combined settings of the SYNC_SEG, PROP_SEG and PHASE_SEG_1 mentioned in the
CAN specification. Alternatively, it could be viewed as the total bit width - PHASE_SEG_2.

Sync Jump Width (%bit)
Specifies the percentage of a bit width to allow for resynchronization adjustments. This
corresponds to the SJW parameter in the CAN specification.
The CAN specification allows for a wide tolerance on node oscillators. This is accomplished
by requiring that nodes resynchronize on passive->dominate edges. The receivers compare
the actual timing of these edges with the ideal timing at the specified baud rate and then
make adjustments to their internal timers to resynchronize with the incoming data. This
parameter specifies the maximum adjustment we will make when resynchronizing.
Increasing this number increases our ability to properly decode packets involving nodes with
low accuracy oscillators at the expense of increased noise sensitivity. Lower numbers
improve noise rejection but reduces our ability to work with nodes with low accuracy
oscillators. You usually set this lower if all nodes use crystal oscillators for their baud rate
reference, and higher if any of them use ceramic resonators or other low accuracy sources
for their baud rate references.
Be aware that the (SAMPLE-POINT + SJW) should be less than 100% and that
(SAMPLE-POINT - SJW) should be greater than 0.
Filter Glitches <= (%bit)
Specifies filtering of pulses that are less than or equal to the specified percentage of the Bit
width.
DigiView has a much higher bandwidth than most CAN receivers so it is capable of
capturing glitches or noise pulses that normal receivers might not even see. Also, many
CAN receivers have different levels of filtering available. This option lets you tell us how
relatively good we should be at rejecting noise pulses. A setting of 0 tells us to process full
bandwidth data with poor rejection. Increasing this setting makes us simulate higher
immunity parts. Selection range is from 0% to 10%.

Check this item to enable Plotting for this signal. If checked, all waveform views will display
plotted data as defined by the Plot Series configurations. You must enable and configure at
least one Plot Series before any plotted data is visible. Up to 4 individual plots can be
configured for each signal. (see: Plotting Signal Data 66 ).
Color Selection & Examples
An example of the signal is displayed in the current color scheme, followed by an example of
the current color selections for this signal and a color reset button. Clicking on one of the
color squares will open the Color Selection 125 dialog to change the Signal line color and its
background color if a color other than the theme color is desired.
Reset Signal Colors
This button will reset the colors for this signal so that they will match the currently selected
color theme (see: Color Themes 113 ).
Channel Options
This is where you will associate a signal definition with the physical channels or connections
to the outside world. Each signal definition type will have one or more channel selection
groups and will allow one or more channels to be selected for each group. Each channel
selection group will be identified on its left if more than one group is available for the signal
type.
To select a channel, click on the " - " below the proper color (and channel number) that
corresponds to the physical connection of the DigiView Cable (see: Connecting the Data
Lines 33 ). Channels that are selected for this signal will replace the " - " with a blue square
as shown above. The gray arrow beneath each channel color is an activity indicator that
displays the activity of the channel as compared to the activity of all the other channels
(relational, not real time).
Clock Channel Selection
Selects which physical channel to assign to the CLOCK.
MOSI Channel Selection
Selects which physical channel to assign to the MOSI data.
Invert Channels
If selected, the captured data for MOSI will be inverted before decoding and displaying

Plotting Signal Data
Signal Definitions 35 can be configured to plot the data when displayed in any Waveform View.
Enabling Plot Output will not affect the data displayed in Tabular views or searched by Pattern
Search 187 and Sequential Search 183 definitions.
Plotting can be configured for a specific field and field slice if the signal has field names. If only a
particular sequence of the data to plot is required, this can be specified by using the single
characters of P or S for Plot and Skip sequences, numbers for repeat counts and brackets for
grouping any of the previous. Grouping and repeat counts can be nested up to 8 levels deep,
giving you the ability to plot a wide range of custom data sequences.
Since the waveform representation of Boolean signals is already a plot of the 2 available states (1
or 0), no additional plotting options are available. All data of a Bus signal will be plotted within the
Data Range selected and since they do not have any framing or field data, only one plot is
available.
All other signal definitions (including those based on custom plug-ins) can each be configured for 4
unique plots.

Data Range (bits)
Select the number of bits to use out of the total bit range of the plotted data. The selection is
from 1 to 32 bits. Selecting a smaller value than the total available will truncate the value and
discard the upper bits. This may be desirable if the upper bits are unused and has the effect of a
coarse gain.

§ Sign & Magnitude
§ Zero Offset
Zero Offset
This value is ignored unless Zero Offset is chosen for the Data Format. Enter a decimal value
within the data range that represents the zero point of the data. Use the button "Range / 2" to set
this value to the middle of the range.

Data Selections
If a selection list is visible, the signal has more than one type of data field. Use the pull down to
select which data field to plot.
Select Data Slice
If Select Data Slice is visible, the selected field represents multiple data slices (indicated by %1,
%2 etc). Select which slice of this field to plot by selecting one from the pull down.
Plot Sequence Editor
Leave this edit box blank to plot all occurrences of the selected field (or field slice). To define a
pattern of field occurrences or skip specific fields in a sequence, enter the plotting sequence in

Using '(', '{' or '[' to group sequences is a personal preference as all are equivalent. However, the
proper closing must be used as documented above. In the graphic above the helper hint
indicates that a group has not been closed and the compiler is expecting a ')' to close it. The
hint also indicates that it is completely valid to open another group using any of the group
specifiers, continue adding sequence characters or enter a repeat count.
Editor Examples

[PS]3[SSP]*
- plot the first 3 even fields (repeats Plot, Skip three times) then plot every
third field thereafter (repeats skipping two fields and plotting the third one).
Restart Plot Sequence on NEW FRAME
When not selected, framing information is ignored and the sequence will be processed until the
end of data or the sequence ends. If selected and framing is configured for the signal definition,
the specified sequence will restart at the beginning of a frame even if the sequence had not
completed in the last frame. If no framing information is present, processing is the same as if the
option is not selected.
3.2.2
Triggers
To capture data before, after or during a specific state of a signal or a change in its state, you
need to be able to specify this condition so the analyzer will start or stop its capture when its
detected. This is called configuring a "Trigger". If you just want to instantly capture data, then set
the trigger option to "Always" (see Trigger Modes below).
DigiView analyzers have a wide array of real-time hardware Trigger options. From a simple
change on one signal, to a specific pattern across multiple signals, a combination of both or a
sequence of matching conditions with event counters, these are all easy to configure from our
Software.
Combining the hardware Trigger with the Analyzer buffer's prefill options, you can capture until
this condition is detected, stop capturing when this condition is detected or divide the capture
buffer data to any percentage of before/after the condition (see ).
The trigger point is marked by the T marker and is always TIME 0. All data prior to the trigger is
negative time and all data after the trigger is positive time. If you stop the analyzer before a
trigger condition is detected, the Trigger is set to the the last captured sample.

To change modes, Click on the button to the right of the current mode indicator. The button's
symbol also indicates the current mode and will change after you select a different mode. In
the image above and below, the current mode is "Always" and the button has a T with
continuous arrows circling it.
Select the desired mode from the selection window.
Always
Configures the hardware to consider any change on any signal as being a matching condition
so it will trigger on the first sign of activity.
Never
Configures the hardware to never trigger so it will continue to gather the newest data until
manually stopped.
Simple
Simple triggers make it easy to configure trigger conditions directly from any signal in any
waveform view. Patterns and Edge detections (changes) can be configured for all or any of the
signals you have in the project. See the Simple Trigger 71 section for complete details.

Simple Trigger
Simple triggers make it easy to configure trigger conditions directly from any signal in any
waveform view. Pattern matching and Edge detections (changes) can be configured for all or any
of the signals you have in the project.
Simple Trigger Symbols
When you have changed the trigger mode to Simple (see Triggers 69 ), the trigger column in all
waveform views will display a trigger condition symbol to the right of each signal's name. The
symbol will reflect the condition set for that signal. Each symbol and its explanation is listed
below.
Multiple States, mixed mode

Rising Edge
Don't care, Ignore
Falling Edge
Pattern of Logic 1
Either edge (any change)
Pattern of Logic 0
Editing Simple Triggers
Click on the symbol next to the signal's name to make changes. Editing the condition is slightly
different for Boolean, Bus and Decoded signals. With Boolean signals you can choose one of 6
conditions (X,1,0,rise,fall,either). With Bus signals, you can choose one of these 6 conditions for
each channel of the bus or select one condition for all of its channels. Decoded signals use a
combination that reflects each of the channel groups it consists of (clock, data bus etc.). An
Example of each is displayed below.

72
Boolean signal example:
The selected condition is highlighted in the selection group to the right and also
displayed next to the signal's name.
Move the mouse over any condition symbol in the selection group on the right then Click to
make it the selected condition.
BUS signal example:
The currently selected condition of each channel is displayed beneath the channel
number.
To change the condition, move the mouse over a channel and the vertical selection group will
move over that channel and highlight its current selection. In the image above channel 1's
current condition is '0'. Clicking on any other condition symbol in the vertical selection group
will change channel 1 to the new condition. Move the mouse left or right until you are over the
channel you want to change, then select the new condition.
To change ALL the channels to the same condition move the mouse over the "ALL" text.
When the mouse is over the "all" text, the selection group will move to the right of it. Any
condition selected will now apply to and update all the channels for that group.
Typical Decoded signal examples:
Each channel group of a Decoded Signal is edited in the same way as a Boolean or Bus
signal. Move the mouse over each group to change the condition just like the Boolean and Bus
examples above.

Advanced Trigger
In our DigiView Software, Advanced Triggers are specified in terms of SIGNALS.
After assigning channels to signal names, you can configure the advanced
trigger condition based on the defined signals (see: Signals 35 ). Most engineers
will find it easier to reference the condition as it relates to the circuit's function
rather than remembering which channels of the analyzer were used to connect
to specific signals in the circuit.

Example of an Advanced Trigger Configuration for Model DV3500:
The Advanced Trigger configuration screen implements a dual-mode (GUI and text),
schematic-like approach to configuring the matches, sequencers and trigger output from a single
window. A text window shows the 'formula' for the configuration while the 'schematic' shows the
flow. These two sections update together to provide two distinct views of the configuration.
Multiple trigger configurations can also be selected and created using the selection area in the
upper left corner of this screen.

send the new configuration to the analyzer. To create, clone, delete or rename a configuration
use the buttons above the selection box.
Trigger Formula (left portion of screen)
The formula presents a summary of the complete configuration. Since this summary can be
quite involved with a complex trigger condition, each section will "highlight" as items in the
graphical section are selected or the mouse moves over them. The formula will automatically
scroll to bring the highlighted section into view while working in the graphical area of the
configuration. In the image above, the summary of "MATCH 5" is brought into view as Match 5

Schematic (right portion of screen)
This area is where the actual configuration is accomplished. For clarification, the graphical
area is divided by two major paths: Direct (non-sequenced) pathways and Sequenced
pathways. Select viewing of each path by using the appropriate Tab at the top of this area.
Note: The Match configuration and Term connections are common to both pathways and will
always display.
Every trigger configuration starts with a match condition and ends with Trigger Out, so the
work flow is designed from left to right, starting with the Match Types (see: Trigger Match
Types 77 ).
Connections
Auto Connect
When the very first Match type is selected and the match condition has been specified, the
match will automatically route graphically to the Trigger Out. For the DV3 series, this means it
will route to TERMS 1, then the DIRECT (NON-Sequenced) option and then to Trigger Out.
This automatic function is only performed if no other connections already exist. Once you have
started making connections for your trigger configuration, the software will not try to "guess"
your intentions, since this would hinder your work. The software allows you to manually
connect or disconnect if the action is valid. Only the obvious connect and disconnects will be
performed automatically.

ADD a Signal - Highlight a defined signal from the left portion of the window and click the "+"
button to add it to the Pattern Match. You can also just "Double-Click" the defined signal to
automatically add it. NOTE: High Level signal definitions (such as State, I2C, or etc) cannot be
added directly as a complete signal. However, the individual portions of the signal (such as Enable
above) can be added in the same manner. To see the sub-portions of a signal, click the "expand"
button in the left column next to the signal's name, then add the sub portions in the same manner
as any other signal.
For instance, if you have defined a State signal like the one above (Address) and you only want to
add the Enable signal to the pattern match, then expand it and double-click on Enable.
Note: If a signal is valid for the trigger configuration, a green icon will be displayed next to it.
Any other icon, such as the blue circle above on the Enable and the Frame Sync channel of
the Address signal, indicates a channel state that is invalid for triggering. The Blue icon in the
Edit area for Enable indicates the channel has been configured as 'Ignored' in the signal
definition editor and is generally "Disabled" (Blue icon in the selection tree on the left). The
Red outline in the edit area indicates an invalid signal has already been added to the

Channel.
Note: If a signal is valid for the trigger configuration, a green icon will be displayed next to it.
Any other icon, such as the blue circle above on the Frame Sync channel of the Address
signal, indicates a signal state that is invalid for triggering. This particular icon indicates that
the signal is 'Disabled'. Selecting Ignore in the signal definition editor for a particular
sub-signal will disable the sub-signal throughout the application.
Delete a Signal - Highlight a signal in the right portion of the window (or mouse-over its bit
selections) and click the "-" button to delete it from the Edges Match.
Changing Bit Pattern - Each bit of the signal can be toggled between the 4 states of '-' (don't
care), 'rising', 'falling' and 'either' by simply clicking on the bit position in the Edges edit area. To
set all bits for a signal to one of these 4 values, use the buttons to the upper-right of the Edges

For instance, if you have defined an I2C signal and you only want to add :Clock(SCL) to the Stable
match, then expand it and double-click on :Clock(SCL). It would then appear on the right portion
of the editor as "AND I2C:Clock(SCL)" like the ALE signal above.
Note: If a signal is valid for the trigger configuration, a green icon will be displayed next to it.
Any other icon, such as the blue circle above on the Frame Sync channel of the Address
signal, indicates a signal state that is invalid for triggering. This particular icon indicates that
the signal is 'Disabled'. Selecting Ignore in the signal definition editor for a particular
sub-signal will disable the sub-signal throughout the application.
Delete a Signal - Highlight a signal in the right portion of the window (or mouse-over its bit
selections) and click the "-" button to delete it from the Stable Match.
Selecting Stable bits - Each bit of the signal can be toggled between the 2 states of '-' (don't
care) and 'STABLE' by simply clicking on the bit position in the Stable edit area. To set all bits for
a signal to one of these 2 values, use the buttons to the upper-right of the Stable edit area.
Boolean signals, if added, do not offer a choice and should be removed when they are no longer
needed as part of the Stable match.
Duration - Enter the stability duration by selecting the units then typing the value. The Maximum
Duration period for Models DV3200, DV3209, DV3400, DV3409 and DV3500 is 5 ms; 10ms for

HEX: Start the value with an "x" or a "0x". If too many digits are entered, the most significant
nibble (leftmost) will be discarded. Any non-HEX digit will be ignored.
Binary: Enter "b" followed by "1's" and "0's". If too many digits are typed, the MSb (leftmost bit)
will be discarded. Any numerical value larger than a "1" or non-numerical character will be
considered a "1".
ASCII: Start the value with a single or double quote.
Duration - Enter the match duration by selecting the units then typing the value. The Maximum
Duration period for Models DV3200, DV3209, DV3400, DV3409 and DV3500 is 5 ms; 10ms for

3.2.2.2.1.5 Not Equal Match
The NOT Equal Match Editor:
ADD a Signal - Highlight a defined signal from the left portion of the window and click the "+"
button to add it as the NOT Equal Match. You can also just "Double-Click" the defined signal to
automatically add it. NOTE: High Level signal definitions (such as State, I2C, or etc) cannot be
added directly as a complete signal. However, the individual portions of the signal (such as the
Data Channel portion of a State Signal) can be added in the same manner. To see the
sub-portions of a signal, click the "expand" button in the left column next to the signal's name,
then add the sub portion in the same manner as any other signal.
For instance, if you have defined a Synchronous Serial signal (i.e. SPI) and you want to add the
:Enable portion of the signal to the NOT Equal match, then expand it and double-click on :Enable.
It would then appear on the right portion of the editor.
The NOT Equal Match type only accepts one signal at a time. If you attempt to add a second
signal, a dialog will appear asking if you want to replace the existing signal with the current one.
Note: If a signal is valid for the trigger configuration, a green icon will be displayed next to it.
Any other icon, such as the blue circle above on the Frame Sync channel of the Address
signal, indicates a signal state that is invalid for triggering. This particular icon indicates that
the signal is 'Disabled'. Selecting Ignore in the signal definition editor for a particular
sub-signal will disable the sub-signal throughout the application.
Delete a Signal - Highlight a signal in the right portion of the window (or mouse-over its bit
selections) and click the "-" button to delete it from the NOT Equal Match.

3.2.2.2.2 Sequencer
The trigger circuit of the advanced trigger mode includes 4 cascadable, 4 stage sequencers.
These can be chained in any combination to produce longer sequences ( [email protected] 16 stages, 2 @ 8
stages...). Stage inputs are OR gates so that more than 1 term of match conditions can be
connected to each stage. Each stage includes a 20 bit pass counter.
Setting a Sequencer Counter
Double-Click in the counter to edit its value. When finished editing, either use the "Tab" key or
click on another item to assign the new value to the configuration. Anytime the configuration
changes, use the "APPLY" button to activate the new settings in the analyzer.
NOTE: "0" is an invalid value, so the counter editor will enforce a minimum count of "1".
Editing of a sequencer counter can also be activated by a Double-Click on the counter item in the
Formula View. In the example below, a Double-Click on either of the darker lines will activate
editing for Sequencer 1, Counter 1. The counter's current value is shown as 243 (the second
darker line) and will update after editing is complete.

Buffer Settings
The settings below apply to all DV3xxx Models of DigiView (such as Models DV3200 or DV3500).
Buffer Size - Adjust to change the size of the Analyzer's internal capture buffer (1% - 100%).
Prefill - Adjust the amount of buffer to use for data captured before the trigger event. If no
trigger event occurs, the analyzer will continuously refresh this portion of the buffer with the
most recent data (circular queue). When the trigger condition is detected the remaining portion
of the buffer will be filled with post-trigger data. The behavior of the prefill (or pre-trigger)
portion of the buffer can be modified by the Enforce Prefill option.
Enforce Prefill - Select this option to force the analyzer to fill the buffer to the Prefill setting
before looking for a trigger condition. If you do not need the full prefill amount before the
trigger condition occurs, then uncheck this option to allow early detection of the trigger.
Capture Time Limit - Select a time-out in the event the capture takes too long to completely
fill the assigned buffer size. If the timeout occurs and no trigger condition has been detected
the trigger point is placed at the very end of the captured data (when the timeout occurs).
Select from 1-99 in seconds, minutes, hours or days.

The settings above also apply to all DV5xx Models of DigiView (such as Models DV509 or DV518)
with the exception of buffer sizing. Instead of a Buffer Size option the DV5xx series, which can
also stream data directly to the PC, has a Buffer Allocation setting that combines a streaming
buffer with the hardware buffer. This guarantees a large capture even with a slow PC or minimal
USB bandwidth.
Buffer Allocation - This new buffer configuration combines the Analyzer's hardware buffer
with a streaming buffer on the PC. Regardless of the data rate, the capture is guaranteed to
store at least enough data to fill the analyzer's internal buffer with compressed capture
records. Our DV5xx series of Analyzers currently have 128Mbits of hardware memory that
stores compressed data from the capture. Since the compression method is automatically
switched while capturing to optimize storage space, this can be an enormous amount of data
(a minimum of 6 to 10 million signal transitions).
Stream Buffer Goal - Adjust this option to select the total amount of signal transitions you
would like to capture. The range is from 1 Thousand to 100 Million.
This is not to be confused with samples. This is the number of actual changes being stored
with each storage location including all channels. Since the state of all channels are stored
whenever any signal has a transition, this setting considers it a single storage transition even
if multiple signals changed on that sample. So the result could be more transitions captured
than the requested goal.
Be aware that this is the Goal setting, which may not match the result. If the PC can not
© 2017 TechTools
99
DigiView User's Guide
allocate the memory or if you are using a USB 2.0 connection while capturing signals with a
very high data rate, the result will be smaller. You will still capture the minimum in the
analyzer's hardware buffer regardless of PC memory, performance, connection type or data
rate.
Current Buffer - This is an indicator of how many "transitions" or storage changes are in the
current capture being viewed.
This will update after a capture is completed or when loading a capture from the history
buffer. It normally will not reflect the exact number requested and can be much smaller than
the Goal if the capture was halted for any reason. If the Capture Limit timeout occurred, or
the capture was manually stopped or if the PC could not allocate enough memory it will be
smaller. In the graphic above the goal was set to 1 Million and the actual stored changes is 6
changes short of the goal. This would be normal due to estimating the required space for a
variety of compression records that could hold this number of signal changes.
If you are capturing multiple channels, then you are most likely to have more transitions than
indicated since all channels are stored when any channel changes and multiple channels
can change on the same sample.
Apply - When highlighted, a change has been made. Click to save the modified settings.
Cancel - When highlighted, a change has been made. Click to discard any changes and reset

3.3.2
Voltage Threshold
The voltage threshold is also known as the Trigger Threshold, Trigger Voltage or Transition
voltage. When capturing the activity (voltage changes) on the channels, this is the voltage level
that determines the difference between storing a 1 or storing a 0.
For a typical circuit where the lowest voltage indicates a '0' and the highest
voltage indicates a '1', you would set this value to the middle of those two
voltages (i.e. for 5 Volt CMOS set the threshold to 2.50 volts).
If too much noise activity is being captured, setting this level higher (away from ground bounce or
noise) or lower (away from peak bounce or noise) will improve the quality of the capture and even
extend the capture time by preventing the storage of phantom transitions or 'garbage'. When
decoding serial protocols, capturing noise can cause poor decoding or no decoding at all.
The number of thresholds, the number of channels and the voltage range varies between models.
These variations are shown below.
The cable(s) and channels affected by the threshold setting are displayed first. This area also
displays the channel numbers, colors and the detected channel activity (relative to each other).
Below the channel indicator area is the current threshold value.
The selection box provides quick selection of standard values to use for common logic families
and also indicates the current value in relation to these common settings. The slider bar beneath
the selection box can be used to manually set a custom voltage. The mouse can be used to move
the slider and once selected by the mouse, the cursor keys can be used for fine adjustment. If the
selected voltage does not match a common selection, an indicator will be placed in the selection

a list of the items that are affected by theme changes along with the current theme color for that
item. Due to the wide range of colors between themes, the Marker Options are saved for each
theme independently and will refresh when changing the theme selection.
Marker Options - When selecting a theme, Marker Options will be updated to the selections
previously used for the newly selected theme. When selecting a marker color set, the Marker
Color Level and Marker Text Level settings will update to the settings last used for the set when
the current theme was last selected.
Window Appearance - This setting will have a dramatic affect on the application's color
appearance and brightness. This setting is independent of the selected color theme and marker
options.
3D Satin Gradient - This
selection paints most
windows with a top to bottom
transitional background
color. The gradient begins
with the Signal Background
color and slowly transitions to
the Frame color by the time
the bottom of the window is
reached. This gives a soft 3D
look with a satin appearance
if there is sufficient contrast
between the two colors. This
also has the affect of slightly
darkening the application's
appearance compared to
using the Flat Tile selection.

Capturing Data

DigiView User's Guide
Capturing Data
Once signals 35 and triggers 69 are defined, you can capture a new buffer of data at any time by
pressing the 'Run' or 'Auto Run' buttons. If you tire of waiting on a trigger or the Analyzer triggers but
you tire of waiting for its buffer to fill, you can manually STOP the capture to transfer the buffer.
When transferred to the screen, the capture is also stored in the capture history for later analysis
(based on Acquisition settings 110 ).
If you have little or no activity after the trigger condition and find the need to manually halt the
capture frequently, you may want to set a timeout period for automatic stopping the capture or
reduce the Analyzer's buffer size (see Analyzer Buffer 97 ).
Preview - This mode will automatically transfer data to the PC repeatedly even if a
trigger condition has not been defined. This mode is very useful to Monitor signals while making
connections and only utilizes a small portion of the hardware buffer. In this mode, the buffer size
and duration of data collection is adjusted automatically to provide a "peek" of the logic activity
and is not intended for normal data analysis. The result is a virtual "LIVE" mode that does not try
to search the data (Auto Search windows) or store the data in the capture history. The data
displayed will be discarded when the results of a normal Run (single shot) or Auto Run are
displayed.
Auto Run - This will "ARM" the hardware, wait for the trigger condition, automatically
display the data and then re-arm to repeat the process until the Stop button is pressed. If you are
waiting on a Trigger condition that you expected to occur, you can select the "Stop" button to view
the data already collected (see Analyzer Options 96 ).
Run - This will "ARM" the hardware and automatically display the data when the buffer
is full or manually stopped. If you are waiting on a Trigger condition that you expected to occur,
you can select the "Stop" button to view the data already collected (see Analyzer Options 96 ).
When you click on 'Run' (or Auto Run), you are actually arming the trigger circuit. After detecting the
trigger condition, the hardware allows the buffer to continue past the pre-fill point and continues to
capture until all buffers are full. After the remaining data in the hardware the buffer has been
transferred to the PC, the hardware immediately resets and halts if you selected RUN. If you
selected Auto-Run, the next capture begins.
Capture Status Window
When capturing or previewing data, a window will open to display several statistics about the data,
the buffer and anything involved with processing that data. The type of information displayed will
depend on your project settings and the Capture mode. A few examples are displayed below.
Stopping the Capture
Press the Stop button to end the capture. If the button turns dark after selecting it without closing
the window, the software is simply busy with a critical task. The request to stop has been seen and
will be performed as soon as the time critical function is complete (such as Compressing the

right corner will display the state of the hardware as simple LED indicators with a letter
abbreviation for a reminder.
Message Example:
The 'Light Bulb" is lit, indicating that a trigger event occurred. The current status is
"Post-Filling", indicating that the remainder of the buffer is being filled with post-trigger data.
Indicator Example:
The Status LEDs above indicate that the unit is powered, a trigger event has occurred and
the remainder of the buffer is being filled with post-trigger data. Descriptions of each LED
are provided below.
P
H
Powered - The analyzer has been detected and is powered.
Halted - The analyzer is 'IDLE' or waiting for a RUN command.
P
Pre Filling - The analyzer is capturing data and filling the 'Pre-Fill' portion of the
buffer.
A
Armed - The analyzer is Armed and actively looking for a trigger condition.
T
Triggered - The analyzer detected a trigger event.
P
Post Filling - The remaining portion of the buffer is being filled with post trigger data.
F
Full Buffer - The buffer is full (normally only active for a split second).
X
Transferring - The analyzer is transferring the remaining compression records to the
PC (normally only active for a split second).
The typical progression of the status indicators is from left to right.
4.2
Capture History
If the "Save capture to History" option is selected (default is off), each capture is stored on the
Hard Drive as a history buffer and maintained according to the settings configured in Acquisition
Options. Each project maintains its own history buffer in a sub folder using the same name as the
project file. However, the project file does not require the history buffer to be present when
opened. This allows the project file to operate as a 'stand-alone' file for sharing or archival
purposes. When saving the project file, the currently loaded capture is embedded in the project
(see also: Acquisition Options 110 ).
History Browsing
The history buffer can be accessed utilizing the History Menu, the Browse button or the bar
graph. These items are located at the bottom of the main window. When browsing the history,
the data for that history item will be loaded and all Signals, Auto Searches, Lists, Tables, etc.
will refresh as if the data had just been captured.

Status Window
To open a new Status Window, use the "Open Feature Window" button (highlighted above) and
select "Status" from the menu. Status windows can be docked, tabbed with other dockable
windows or placed on any monitor (see Window Arrangement 9 ).
The Status Window displays key statistics of the current capture being viewed, the Capture History
and the last Analyzer Run. These statistics will be displayed for any capture in the history (when
loaded for viewing) and for any new captures (whether stored in the history or marked for
discarding).
The Status window displays the following:
Captured Samples - Total number of samples stored in the loaded capture. Samples are
always at the full configured resolution of the Analyzer. DigiView never down-samples or
discards samples in a capture.

Capturing Data
136
Total Timespan - The total time covered by the stored samples in the loaded capture, from the
first sample to the last sample.
Capture History ID - A unique identifier is assigned to each capture and used for storage and
bookmarking purposes. The ID of the loaded capture is displayed here. This ID is also used as
the filename extension in the capture history sub folder.
Data and Time of Capture - The date and time (in millisecond resolution) is always stored when
a capture is transferred to the PC from the Anlayzer. This is the actual capture time and may not
always match the file date and time. This data is stored in each capture and can not be modified.
Note: When opening older projects that did not store the capture date and time, this will display
the project's data instead.
Files in History - The Capture History is stored in a sub folder using the Project's name. This is
the total number of compatible captures located in this directory that have been indexed by the
project. The history is re-indexed whenever the project opens, captures are deleted or an
indexed capture file is missing (by manual deletion, drive corruption, etc). If a capture is
discovered to be missing while browsing or jumping to its index, the closest chronological
capture to the missing index will be loaded instead.
Saves/Captures this run - This statistic is updated whenever a capture is transferred to the PC
or the Analyzer is halted and tracks the number of captures saved in the Capture History
compared to the number of captures retrieved from the Analyzer since the Analyzer was last
armed. Acquisition settings, Auto Search Settings and Plug-ins can determine when to discard
or save a capture. Note: Preview data is not stored in the capture history.

Navigating and Analyzing the Data
This is where you spend most of your time; trying to make sense of what you captured. You will
find DigiView software very intuitive and easy to use but it is important to realize that ZOOM
operations occur about the CENTER of the screen (the "@" reference). The tools are all
designed to take advantage of this fact to make you more productive.
The general paradigm is to find points of interest, bring them to the center of the screen and then
ZOOM. We provide several methods of finding edges and bringing them to the center of the
screen so that you can zoom in and out without having to constantly scroll to 'zero-in' on the point
of interest.

Waveform Overview
The main application window has two Waveform Views permanently placed in the center.
Additional Waveform Windows can be added and docked or positioned independently on any
monitor (multiple monitors are supported). The Primary and Secondary waveform views are
shown below.
The Center Time Bookmark (center time reference) is considered "Center" because all
operations center around this point and the 'Center time' displayed at the top of the Time
Division area refers to its position. In the top Graphic above the Center Time is 21.36us and
the bookmark is seen directly beneath it. Although it designates the center of operations, the
bookmark can be moved left or right of center to suit your preference. The '@' reference point
can be repositioned by moving the mouse over it until the special cursor appears, then click
and drag it.

Toolbar Buttons
We make extensive use of the right mouse button. Most functions have naturally paired
operations. Most paired functions are natural opposites (like left/right, in/out, first/last,
previous/next). We take advantage of this symmetry to double up the functions of most buttons
and other clicks. This not only reduces desktop usage but also results in more natural, easier to
remember functions.
For example, rather than having both a SEARCH LEFT and SEARCH RIGHT button, we have a
SEARCH button. Left clicking the button will SEARCH LEFT; right clicking will SEARCH RIGHT.
After only a few minutes of use, this becomes much more natural than using separate buttons.
Switching directions involves pressing different mouse buttons rather than moving the mouse to a
new button in the application. All buttons in the tool bar above the Waveform View are
dual-function except the Menu button and Link Group indicator. Additionally, you will find that left
and right clicking in Waveform Views on the " < " and " > " symbols, Marker column and various
other areas will perform similarly paired functions.

Mouse Functions
The mouse is used heavily in Waveform Views. Using the mouse In these views you can perform
a wide variety of functions that are summarized below.
Place markers
Drag and place markers or auto-snap to the next Signal change (see Using Markers
151
).
Take Measurements
Select from a variety of measurement methods. View instant measurements while moving the
mouse. Perform quick measurements between two points by using the middle mouse button or
see the time between a marker's current and last position after snapping or dragging it (see
Measurements 161 ).
Navigate
Click anywhere in a waveform to bring that point of time to the center of the screen. If you are
within a few pixels of a change in the signal it will scroll to the center of the screen instead (Edge
Snapping). Hold the Control Key when clicking near an edge to override Edge Snapping.
Scroll the the next or previous change of a signal to the center of the screen by using the button
in the Snap Signal Column 146 to the left of the waveform.
Drag Scrolling
Right-Click and Drag the mouse on a waveform to perform a 1:1 scroll in the horizontal
direction. Right-Click and Drag the mouse vertically to scroll additional waveforms into view.
Hand scrolling will not scroll vertically and horizontally at the same time so it chooses the
direction based on the initial drag and displays arrows indicating the chosen direction. If you do
not drag after using the Right-Click, the Waveform Menu will appear.
Free Scrolling
Along the bottom of each Waveform View is the Bird's-Eye Scrollbar
position, jumping to another position or scrolling freely in the data.

Snap and Value Columns
At the end of each waveform are two additional columns: The Snap Signal column and the
Value/Marker Snap column.
Snap Signal Column
Scroll the next or previous change of a signal to the center of the screen by using the button in
the Snap Signal column at the end of the waveform. Use the Left mouse button (Left-Click) to
snap the previous transition into view. Use the right mouse button (Right-Click) to snap the next
transition into view. The transition will scroll to the Time Reference point in the center of the
screen (labeled '@' and visible to the right of the red marker below).
The Snap Signal column is the first column to the right of the waveform:

Signal Value and Marker Snap Column
The Value/Marker Snap column has multiple functions and a local menu for configuration
options. It is the last column in the Waveform view, just after the Signal Snap column.
Column features:
1. Displays the value of each signal at the selected Time Reference (Time Source).
2. Displays which waveform is currently assigned to the selected marker (Active Marker) by
using the marker's colors.
3. Is used to assign a different waveform to the Active Marker without changing the marker's
position.
4. Is used to snap the Active Marker to the Next or Previous edge of the assigned waveform.
5. Indicates the position of the currently selected marker (Active Marker) relative to the screen's
Center Time reference (marked by the movable '@' tag). This Delta measurement is
displayed at the very top of the column using the same colors as the selected marker.
6. Indicates the Time Source selection (for the column's waveform values) on the Time Source
button.
Example of assigning a marker to another signal without moving the marker's position:
Click once in the column to re-assign the marker to another waveform. Once assigned, any Left
or Right click will move the marker to the previous or next edge of the waveform. Holding either
mouse button down will repeat the function. If the marker's "scroll to @" function has been
enabled, the waveform's new marker position will scroll to the Center Time reference point ( also
see: Using Markers: Marker Quick Menu 153 ).

Time Reference Selections:
1. (@) - Center Time (the '@' indicator, live value update when jumping, snapping or scrolling).
2. (A) - Active Marker Position (live value update with marker movement).
3. (M) - Mouse Position (live value update with mouse movement).
4. (T) - Trigger Position (static, values of each waveform at time 0).
Click the Time Source button at the top of the value column (above the waveforms) to change
the Time Reference for the displayed values. This button also serves as an indicator to remind
you of the current setting.
In the images above, this button displays the letter "A", indicating the values displayed for each
waveform are from the time corresponding to the Active Marker's position. In the images below,
the button indicates a selection of "Center Time", which is the time corresponding to the screen's

Bird’s-Eye Scrollbar
The Bird's-Eye scrollbar gives you the really big picture. It shows the relative zoom and position of
the waveform window to the total data. As you navigate through the data, you can look at the
Bird's-Eye to see exactly where you are in the data and how fast you are progressing through it.
You can also use it to scroll through the data, jump to another area or jump directly to a marker.
The total data is shown as a transparent box with an outline. When zoomed out, the portion of the
data being viewed in the waveform window ("screen" area) is indicated by a rounded rectangle
with vertical dividing lines corresponding to the 10 time divisions of the window.

Navigating and Analyzing the Data
150
Dragging the screen area of the bird's-eye will scroll the window view.
When the window is zoomed in on a small percentage of the data (usually the case) the waveform
screen representation becomes a pointed tag with the point indicating the center of the screen in
the total data ("you are here" indicator).
Each of the markers (and its complement if split) are also shown with color-coordinated lines. If the
currently selected marker has been Split, the area between the marker and its complement is
indicated with slanted slash marks in the color of the marker (see Using Markers 151 ).
You can click on the Bird's-Eye scrollbar to jump to any position in the data. If you hold the Control
Key while clicking near one of the markers, the waveform will "snap" to that marker's position.
However, since the amount of time captured is so large compared to the available pixels on a
monitor, you may not notice when several markers are represented by the same pixel. When
several markers are represented by the same pixel the first represented marker will be chosen.
5.1.5
Marquee Zoom
You can use your mouse to marquee an area of data to zoom in on. Left-Click and drag to
marquee a section. When you release the mouse button, the enclosed area will pan to the center
of the screen and them zoom in as much as possible while keeping the entire area on the screen.
While holding the mouse button down to marquee, the area to zoom will darken. To cancel the
marquee simply drag back towards the starting point until the darkened area disappears and
release the mouse or drag completely away from the waveform area and release the mouse.

Zoom History
If you accidentally marquee, Left-Click on the "Previous/Next View" button to return to the
previous zoom level and position. Hold the mouse button down to repeat the action and go to
earlier zoom levels and positions. If you go too far, Right-Click on the button to go forward through
the view history (hold to repeat).
5.1.6
Using Markers
Six main markers (M1 - M6) are provided and each of these markers can be split to form a marker
pair (Main Marker + Complement), making a total of 12 markers available for measurement,
bookmarking and other purposes. Complement markers are always displayed in the reverse color
of their main marker and may also display a lower case 'c' after the marker number.
The benefits from using DigiView's markers start to become obvious when seeing the variety of
available uses:
§ Measure time from an edge of a signal.
§ Measure time from the Trigger Point (also see Marker Time/Delta 171 ).
§ Measure time from its complement marker or from any other marker (also see Marker
Time/Delta 171 ).
§ Bookmark specific spots in the capture and jump to those spots with a single click or keystroke
(see Quick Select Flags 152 , Key Functions 159 ), .
§ Bookmark a time span in the capture to quickly scroll and zoom that period into view with a
Double-Click or keystroke (see Marker Time/Delta 171 , Key Functions 159 ).
§ Snap to the Previous or Next change in a signal and scroll that point to the Center of the screen
(@).
§ View the value of multiple signals at the marker's time in the Marker Column.
§ Scroll a waveform vertically into view when activating its assigned marker.
§ Mark a time span for exporting (see Exporting 196 ).
§ Automatically scroll to and mark the result of a Pattern Search 187 function or a specific stage of
a Sequential Search 183 function (also see Auto Search Windows 190 ).
The most convenient access to markers and their options is the Quick Select
Flags 152 in Waveform Views. Perform single-click jumping, placement by
dragging, splitting, clearing and activate marker menus from these flags.
Markers are global to the application, so any changes will be reflected throughout the program.
The only exception to this rule is the marker that is currently active in a particular Waveform View.
Each Waveform View maintains its own status of which marker is the local "active marker". Each
signal's value that corresponds to the active marker's position in a Waveform View is displayed in
the marker column.
The Active Marker
The Active Marker is the marker currently being used or selected. Dragging a marker, jumping
to a marker, changing its options or performing a search will automatically set the marker
involved as the Active Marker.
Items affected in Waveform Views when a marker becomes the Active Marker:
§ Quick Select marker flag highlights.
§ Marker Flag highlights and is brought in front of other flags.

Navigating and Analyzing the Data
152
§ The Marker Column reflects each signal's value at the Active Marker's time.
§ The time displayed at the top of the Marker Column is the time from the Active Marker to the
Center Time of the Waveform View (@).
§ The time displayed at the top of the Marker Column is highlighted using the color of the Active
Marker.
§ The Snap Marker buttons at the top of the Snap Signal Column changes to the same color as
the Active Marker.
§ A right or left click on the Snap Marker buttons will snap the active marker to a signal edge if
the marker is assigned to a signal.
§ The static measurements will display for the active marker in full color and on top of any other
visible marker measurements.
§ When the Active Marker is moved or snapped to an edge it will display the time from its last
position to its new position. If split, it will display the time from the position of its complement
instead.
§ If "Scroll-n-View" is enabled and the Active Marker is assigned to a signal, the assigned
signal's waveform will scroll into view if not already visible.
The Quick Select Flags
The Quick Select flags are located in the upper left corner of all Waveform Views. From these
flags you can jump to a marker's position with a single click, place a marker, split a marker to
create a tethered pair (creates the "complement"), clear a marker and open the marker menus.
These flags use the same colors as those defined for markers in the Color Theme. The active
one is always highlighted as displayed for Marker number one above (referenced as 1 or M1).
Dragging from these flags will bring the marker to the current screen position and make it
visible if necessary.
Clicking on one of these flags will automatically scroll the waveform view to the markers
position and center it in the waveform window. This can also be referred to as "Jump to Marker
".
The last flag (after the flag for M6) is a Global Flag that affects all markers. A Left-Click on this
flag will clear all markers including marker complements. A Right-Click will open the Global
Marker menu 154 .
Quick Select Mouse and Key Functions
§ Left-Click - Scroll the position of the marker to the Center of the screen (@).
§ Click-n-Drag - Activates and brings the marker to the mouse when the drag begins. Position
the marker for placement before releasing the mouse.
§ Right-Click - Opens the Menu for this marker.
§ Control Key + Click - Scrolls to the position of the main marker's complement. If not already
split, the marker will be split and the complement placed at the Center of the screen.
§ Control Key + Click-n-Drag - Activates and brings the marker's complement to the mouse
when the drag begins. Position the complement marker then release the mouse when ready. If
the main marker was not already split into the main/complement pair, it will automatically split
so the complement can be brought to the mouse position when the drag begins.

DigiView User's Guide
§ Control Key + Right-Click - Opens the Menu for this marker's complement. If not already
split, the marker will be split and the complement placed at the Center of the screen before the
menu opens.
§ Mouse Move - When the mouse moves over a flag, the associated marker's flags will
highlight and display on top of other marker flags.
§ Control Key + Mouse Move - Activates the associated marker as the "Active" marker, but
does not scroll to its position. The marker's flags will highlight and display on top of other
marker flags.
Marker Quick Menu
Activate a marker's menu by a Right-Click on the Marker Flag. You can also use the Quick
Select flags to activate this menu, but to access the menu of a marker's complement from the
Quick Select flags, use Control-Key + Right-Click. The menu for M2 and the menu for it's
complement are displayed above.
§ Clear - Disables and removes the marker from view. If split, the complement is also
cleared.
§ Scroll to @ on Snap - Toggles the marker "tack" or "sticky" state. When enabled, the
marker will always bring the point of placement to the center of the screen (@). This will
occur whenever the marker is placed on a signal, dropped in the Division tick area or
snapped to a signal's edge.
§ Split - When enabled, the marker is split into a pair of tethered markers. We refer to the
original marker as the Main Marker and the newly created marker as its Complement.
When split, the static measurement for the marker will measure the time between the
marker and it's complement instead of tracking it's last position. Quick select flags will have
two "dots" above the marker number to indicate the split. The complement marker is
always displayed in the inverted colors of it's main marker and has a lower case 'c'
appended to its designator in many cases. Disable this option to clear the complement.
§ Lock with Complement / Main Marker - This option is available after splitting a marker.
Enable this option to lock the distance between a main marker and it's complement.
Dragging, snapping or placing either marker will also move the other but the distance and
order will remain the same. When locked, the Quick Select flags will connect the two dots
above the marker number to indicate the pair is locked. Disable this option to unlock the
pair and allow each to move independently.
§ Goto Complement / Main Marker - This option is available after splitting a marker. Click
this option to jump to the position of the other marker in the pair. If you opened the menu
for the complement, you will jump to the location of the main marker.

§ Zoom to Split Pair - This option is available after splitting a marker. Click on this option to
bring both markers into view. First, the Waveform View will Zoom to a resolution that fits
the time span of the marker pair, then it will scroll that time span to the center of the
window (@). If the Center indicator (@) is not centered, drag it to the center to see both
markers.
Global Marker Menu
The Global Marker Menu affects all markers. The first two items are global settings that
involve markers and the remaining items change the settings of the actual markers.
§ Enable Scroll-n-View - Enable this feature to have a waveform scroll into view whenever
you activate the marker last assigned to it. This can be beneficial if you are analyzing
multiple waveforms that can not be viewed in the screen area at the same time and do not
want to manually scroll each into view as you jump back and forth between them. If you are
using the markers to jump to multiple time points, when you click on the marker the position
will horizontally scroll to the marker and the waveform will vertically scroll to display the
signal's waveform.
§ Show Static Measurements - When enabled, marker measurements are always visible on
the screen based on Environment options. Disable this option to temporarily hide these
measurements (see Environment Settings 127 ).
§ Clear All - Click on this item to clear all markers including their complement. When cleared,
the markers are no longer visible and each marker's options are reset.
§ Set Scroll to @ on Snap - This will enable the "Sticky" function of all enabled markers. This
can also be set independently for each marker by using the Marker Quick Menu.
§ Clear Scroll to @ on Snap - Clears this setting for all enabled markers. This can also be
set independently for each marker by using the Marker Quick Menu.
The remaining items are visible depending on the current settings of all enabled markers.
§ Clear Compliments - If any enabled marker is split into the Main/Complement pair, the
complement will be removed. This can also be done for specific markers by using its Quick
Menu.
§ Lock All Split Pairs - This will lock the distance between the Main/Complement pair of any
split marker. This can also be done for specific markers by using its Quick Menu.
§ Unlock All Split Pairs - This will unlock the distance between the Main/Complement pair of
any split marker so that each half can move independently. This can also be done for
specific markers by using its Quick Menu.

Drag to Place
Simply click on a marker and drag it to the area of interest. You can grab the marker itself (the
vertical line in the waveform area) or its 'flag'. When your mouse is in the capture zone for a
marker, the cursor changes to indicate that it is over a marker. The cursor also indicates
which marker will be selected, making it easier to grab a specific marker when they are very
close together (or even on top of each other). If the marker is off-screen or not visible, use the
Quick Select flags to grab the marker and place it.
Auto Snap
'Snapping' the markers to signal edges makes it easy to measure the time between them or to
bring a specific edge to the center of the window. This operation is used so often that we
optimized it by making it an automatic function. When you are dragging a marker and your
mouse is over a waveform, the cursor changes to a 'snap-left' or 'snap-right' arrow. The
direction of the arrow shows you which edge (previous or next) of this waveform the marker
will 'snap' to if you were to drop it at that point. The arrow will point to the nearest edge or to
the nearest edge in the direction of mouse movement, even if that edge is off-screen.

The time from the marker's last position is measured to the proposed drop point even if one or
both points are off screen. In the graphic above, the marker's last position was off screen.
Using the Quick Select flags we performed a marker drag on M3 and are moving it to the left
over signal "CODE: Clock Channel". The snap indicator is drawn around the previous signal
edge since we are moving to the left.
The Marker column changes to the marker's color indicating the marker is now assigned to
that signal.
After releasing the mouse button, the marker snaps to the proposed edge and the time
between the marker's current position and the center Time Reference point (@) is displayed in
the upper left corner using the marker's color. Below, we see this measurement to be 900ns.
We also see the measurement from the marker's last position to its current position just above
the signal's waveform. Below, we see that measurement as 3.52 us.
If you DO NOT want to SNAP, but rather wish to drop the marker exactly at the mouse
position, you can either hold down the Control key or move your mouse above or below all
waveforms before releasing the mouse button.

Snap and Measure
'Snapping' markers to signal edges makes it easy to measure time between them or to bring a
specific edge to the center of the window (when "Scroll to @ on Snap" is enabled). When a
marker is assigned to a signal, the marker column uses the same color as the marker. To
snap to the previous or next edge, use the left or right mouse button respectively. In the
graphic below we Right-Clicked in the marker column, causing the marker to snap to the next
edge of the signal and measure the time from its last position (also see: Snap and Value
columns 146 ).
To assign the marker to another signal, Left-Click in the marker column of another signal. The
first click assigns the marker. Any additional clicks will perform snap operations. If you drag a
marker over a signal it automatically becomes the assigned signal.
Split Marker
All main markers (M1 - M6) can be split form a tethered marker pair (a Main Marker and its
Complement). To split a marker, Right-Click on the marker's flag and select "Split".
When splitting a marker, its complement is placed at the Center Time reference (@) and the Complement
marker is activated as the "Active Marker", meaning all indicators that reference the active marker will now
display in reverse colors since complements use the inverted color of their main marker. If we select the
main marker all indicates will return to the main marker's colors. The time measurement now reflects the
time between the pair.

If you look closely at the Quick Select flag for M3 you will see two small dots above it. This indicates the
marker is split and each half can move independently.
To lock the pair, move the markers to the desired position, Right-Click on the marker's flag
and select the "Lock" item. The selection text will be "Lock with Complement" if you clicked on
the main marker's flag, but will be "Lock with Main Marker" if you clicked on the Complement's
flag.
After selecting lock, the marker pair will always move together no matter which of the pair is
the active marker. This includes dragging, snapping and placement by other means such as a
search result (see Searches 181 ). The two dots above the Quick Select flag will be connected
to indicate the split pair is locked.
The graphic below shows how the distance between the two markers remains the same even
after we snap the main marker several edges to the right. You can use this technique to
readily compare a time span of multiple points in the captured data without having to mark or
remember the precise period of each.

Measurements
A wide range of measurement features are available from automatic instant measurements to user
selected dynamic measurements. Dynamic measurements update based on which waveform the
mouse moves over and changes its time span when a Quick measurement is being performed.
Each section below covers a unique method of calculating and displaying measurements to assist
your analysis of the captured data. The Marker Delta window has the added benefit of Zooming
and Scrolling a measured pair of markers into view when Double-Clicked.

Instant Measurements
While moving the mouse over any waveform a measurement is displayed directly above it (see
Environment Settings: Waveform Views 129 ). The type of measurement is dependent upon the
signal type and the mouse position in the waveform. Vertical lines and arrows are displayed to
indicate which edges are being measured. The measurements are calculated even if the
beginning and ending points of the measured item are off-screen.
Use this toolbar button to toggle Instant Measurements On/Off in a waveform view.
Boolean Example
Mouse is between two edges so instant measurements calculates the time period between
those edges. In the graphic below, the Period between the edges is 1.692 microseconds.
When the Mouse is on an edge, instant measurements uses the previous and next edge to
calculate the duty between the edge under the mouse and the previous one. If this is a low
period then Low Duty is represented, otherwise High Duty will be represented. In the graphic
below, the Low Duty is 51.30%.
It also calculates the Period and Frequency from the previous edge to the next one as depicted
by the arrows. In the graphic below, the Period is 3.3 microseconds and the Frequency is
303.030 KHz.

162
Example for Signals with Field and Frame data
When the mouse is within the edges of a Field, the time period of the Field is calculated. In the
graphic below, the Period for the Field under the mouse is 23.1 microseconds.
When the Mouse is on the edge of a field, instant measurements calculates the Period and Field
Count of the Frame the Field belongs to. In the graphic below, the Period for the entire Frame is
83.784 microseconds and the Frame contains 4 Fields. The period and count are calculated
even though the frame begins or ends off-screen.
Example for Signals with Plot Enabled
When a signal is in plotting mode, Instant Measurements will function on the Plot data and
display the value of the plot at the mouse point. If multiple plots are enabled for the signal,
Instant Measurements will function on the selected plot. Pressing the Space Bar will toggle the
plot selection without having to move the mouse.
In the first graphic below, the bottom plot is being measured. This is identified by its plot handle
being highlighted in the plot's color. The Signal Snap arrows in the next column are also the
same color as the plot and the marker column displays the selected plot's identifier. These items
will change to identify the active plot.
In this case we used "Left_Channel" and "Right_Channel" to identify the two enabled plots for
the Audio signal. After pressing the space bar once, the second plot becomes active and instant
measurements will track its values as displayed in the second graphic ("Right_Channel" plot is
active).

DigiView User's Guide
After pressing the space bar, the other plot value is displayed while moving the mouse.
A dotted Vertical line is always drawn at the mouse point and a small square surrounds the point where this
intersects with plotted data. The value at this intersection is displayed in the Instant Measurement.
5.2.2
Quick Measurements
With Quick Measurements you can instantly perform multiple measurements in a waveform by
using the Middle Mouse Button. Click the middle button and move the mouse to display
measurements from any position (including over markers) to another position. These
measurements are unique to the signal type and whether the Signal Definition has plotting
enabled. You can also measure the period between two edges across multiple signals.
A simple period measurement is always displayed above the waveform between the two points
while performing the Quick Measurement. However, additional measurements will appear in a
floating window that hovers near the mouse. To dismiss the Quick Measurement, simply click
again using any mouse button or use the ESC Key.
Note: While performing a Quick Measurement, any Dynamic Measurement 161 windows in the
same link group will use the period measured as the time span.
Note: Using the Control Key will override Signal Edge Snapping while measuring. (also see
Environment Settings: Waveform Views 129 )
Measure across multiple signals
Quick Measurements will snap to a transition edge (when near) and remember the Signal of the
starting and ending measurement point. The measurement is always displayed for the signal
currently under the mouse. However, if the starting signal is different than the ending signal, an
additional arrow is displayed in the starting signal at the starting point.

When a signal is in plotting mode, Quick Measurements will calculate using the Plot data
between the two mouse points. If multiple plots are enabled for the signal, Quick Measurements
will function on the selected plot. Pressing the Space Bar will toggle the plot selection and
refresh the measurements without having to move the mouse.

Dynamic Measurement Window
Dynamic Measurement Windows offer a variety of measurements that can be selected for each
type of Signal group. As the mouse moves over the waveform of a signal, the selected
measurements for that signal type will recalculate and display in the window.
To open a new Dynamic Measurement Window, use the Open Feature Window button
(highlighted above) and select "Measurements" from the menu. Dynamic Measurement windows
can be docked, tabbed with other dockable windows or placed on any monitor (see Window
Arrangement 9 ). The images below are examples of how the measurements change based on
the signal group (Boolean, Bus, Decoder/Parsed, Plot).

Signal:
The name of the signal being measured.
Group:
The measurement group compatible with the signal. The selected measurements of this group will
be calculated and displayed in the window. If the signal has plotting enabled, the Plot group of
measurements are displayed for the currently active plot. The Plot Series number (S1, S2, S3, S4)
will be prepended to the value as a reminder of which Plot Series is active for the signal.
Span:
This indicates which Time Span is being used for calculations; Waveform Window or Quick
Measurement. By default, the time span of the waveform window that is responding to mouse
movements is used. However, while performing a Quick Measurement 163 , this will automatically
change to use the Quick Measurement's time span (and recalculate the measurements
accordingly). When the Quick Measurement is no longer active (middle mouse button is released)
the time span reverts back to the Waveform Window's time span.

Locking the Span & Signal:
After moving the mouse over a signal you can Lock the Dynamic measurement and jump to
specific measurement items such as the Lowest Value, or Longest Duration. Any measurement
with this feature will have an outline indicating it is a clickable line item that will scroll any linked
windows to the location of the result. You may not see any clickable line items or you may see
several depending on the signal type and the selected measurements.
In order to use the mouse to Click on one of these items, you must first "Lock" the measurements
from the Waveform View your mouse is over. Simply use the Control+L Key or Right-Click and
select "Lock/Unlock Dynamic Measurements" from the menu.
As seen above, the lock indicator will change for any Dynamic Measurement windows in the same
link Group. You can also unlock the window by clicking on the indicator.
Jump to Measurement Result:
Click on any measurement item with an outline to go to the location of the result. The outline
indicates it is a clickable line item that will scroll any window in the same link group to the location
of the measurement. When you mouse over these items, the location is displayed in a popup hint
(as seen in the image below). Note: The window should be locked before clicking on any item to
prevent the contents from changing. If left unlocked, the measured items will update while scrolling
to the location clicked (see Locking the Span & Signal above).
In the image above, clicking on the item under the mouse will scroll any waveform or tabular view in Link Group
1 to the time indicated in the hint ( -8.89428 ms, also see Link Groups 180 )

While most manufacturers provide table views,
they generally are not too useful for anything
other than STATE mode signals. Most logic
analyzer demos will show data changing on
every sample, making the table view look
interesting in timing mode. However, in real
usage, most signals do not change at anywhere
near the sample rate, causing the table to show a
small sample of stable data. You might have to
scroll several screens before seeing the signal
transition. We have added several
enhancements to the basic table view to make
them truly beneficial in real-world usage.
Compressed View
This mode compresses out the 'dead-time' between transitions, packing a lot more
information into a screen of table data. Each line of data in the table contains the
timestamp and the data. The time between lines varies and corresponds to the length of
time the previous sample was stable. In this mode, a 40 line table contains 40 transitions.
In linear (non-compressed) mode, it would contain 40 SAMPLES with perhaps NO
transitions. If multiple signals are added to the table, the compression algorithm takes ALL
signals in to account. A new line is shown any time ANY of the signals change state.
Nothing is lost or thrown away. We simply compress out the redundant information,
making the table hold more significant data. You can switch between compressed and
linear views with a single click at any time.
© 2017 TechTools
175
DigiView User's Guide
Although compressed mode is the most efficient way to display a signal in tabular form,
some people have trouble visualizing the non-linear, compressed time. You can Link a
compressed table with other non-compressed tables or with waveform displays to
correlate the data to a linear view. This allows BOTH an efficient table view and a linear
'in-context' view.
The included '8051.dvdat' example demonstrates this well. The OE signal in that example
is spread across about 1.4 Million samples but can be displayed in less than 20 table lines
when compression is enabled. When this table is linked to a waveform view, scrolling
through this small table quickly scrolls the waveform to each significant event in the OE
signal. This is a real-world example captured from a real embedded system.
Delta vs. Linear time
Regardless of the display mode( normal, compressed or down-sampled), you can display
the time field in absolute or delta time. Absolute is the actual timestamp of the sample
(relative to trigger). DELTA mode shows the time between table lines. This is most useful
in compressed mode where it tells you the time between transitions. In normal and
down-sampled modes, it simply tells you the sample rate( since the time between each
line is constant).
Table Menu
The table's menu offers several useful functions such as navigating to a reference point,
adding additional signals, configuring the time and so forth. Example of this menu is
displayed below.

Table Signal Menu:
5.4
Tabular Views
Tabular views (also called List Views or Decoded List) present the decoded data of signals in a
column form. Tabular views can be created after defining any signal.
Tabular Views can be created by using the Feature Window button on the Top Toolbar 7 , by
using the local menu of a signal in Waveform Views 138 or by using the Main Menu (Menu->
Window-> New-> Tabular View). Selections in the Main Menu and Feature Window lists are only
available after creating a Signal Definition 35 .
All signals, from Boolean and Bus to Protocol decoding or any Plug-in signal can be displayed in
the List window. However, to see only the raw channel data of a Decoded signal in tabular format
without any decoding, use a Table view instead. (see: Table Views 173 )
To create a new Tabular View, select the Open Feature Window button (highlighted above)
from the main toolbar, then select the signal name from the Tabular View menu item. If you
select a Boolean or Bus signal, a Table View 173 will be created instead. Only the Signal

Using Link Groups
Link groups provide Synchronous Scrolling of a group of windows that display data. When
several windows are part of the same Link Group, each window will automatically update and
scroll when any member of the group changes its center time. The time reference and displayed
data of each member will "center" on the time the changing member centers on. This feature
keeps a group of windows synchronized to the same time in the captured data.
DigiView provides five link options that include Link Groups 1 through 4 and a "no-link" option for
windows that you want to keep independent.
Default link groups:
Link Group 1 this group.
Link Group 2 Link Group 3 Link Group 4 -
Waveform View 1 is always a member and all new windows initially belong to
Waveform View 2 is always a member of Link Group 2.
Empty Group, ready for members.
Empty Group, ready for members.
The link group of any window that displays data (such as Tables and Tabular Views), can be
changed at any time. To change the group in these windows Click on the Link Group Indicator on
the window's toolbar or select Link from its menu (Menu-> Window-> Link). Link options are
displayed in the following graphic.
© 2017 TechTools
181
DigiView User's Guide
All windows or views that are assigned to a link group will have a visible indicator with the group
number or an " * " (asterisk) displayed. The Primary and Secondary Waveform Views are
permanently assigned to groups 1 and 2 respectively. All other windows can be assigned to any of
the 4 link groups or set to be independent of link groups (*). A small arrow is displayed in the lower
right corner of the link group indicator if the group assignment can be modified.
Link Group indicator:
NOTE: When Waveform View 1 is "cross-linked" to Waveform View 2, all members of Link
Groups 1 and 2 will also be cross-linked. Waveform Views are cross-linked by using the Link
button on the Top Tool Bar. (see Top Tool Bar 7 )

Searches
When analyzing the captured data, the ability to search forward and backward for specific pattern
matches or packet values is indispensable. DigiView provides a general search type for pattern
matches, a Sequential Frame and Sequential Field search for decoded/parsed/plug-in signals and
a Search Manager to quickly perform multiple searches and change criteria.
DigiView also provides a Capture History Search feature that utilizes any defined search to iterate
through the entire history and load the capture that meets the match critera.

New searches are defined by opening the Search Manager 188 window and clicking on the "New"
button or using the main menu (Menu-> Search-> New Search) then selecting the signal to
search from the selection list. Depending on the type of signal selected, a Pattern Search or
Sequential Search will be created and its editor window will automatically open. For example, if
you have selected a signal of type "I2C", then the Sequential search type will be created. (For
details on each search types, see: Search Types 183 ).

After a search is created it will be available in the Search Manager 188 and all
search selection windows, including selection for Auto Search 190 windows and
searching the Capture History 133 files.
All search types (and therefore all search editors) have the following common properties.
Search Name - Description
Use the Name field to describe the search. This descriptor will be displayed in the Search
Manager Window and any search selection box.
From - Where to begin Searching
The 'search from' selection determines where the search starts from; the current center of
screen or the current marker location. Since the marker is placed at the center of the screen
after the first search match, these are often the same during consecutive searches. The main
difference occurs during the first search or between searches if you scroll the screen.
Set Marker - Mark the match point
The marker selection determines which marker is used to show the search match. You must
select one. Whenever the search matches, the selected marker is placed at the match point
and then centered in the searched window.
Delete Button - Deletes this search
Use the Delete button to dispose of the search and remove it from all search managers.
Close Button - Closes this search editor window
Use the Close button when you are finished making changes and want to close the editor for
this search.
Search Button - Performs this search
Use the Search button to test the settings you have just entered for this search. Right-Click to
search forward from the current time of the marker. Left-Click to search backward from the
current time of the marker. When you are satisfied with the search settings, you can close the
search and use any search button in the application to continue searching. (see: Searching 188 )

DigiView User's Guide
Search Types
Searches are defined in terms of Signals matching specific criteria. Depending on the search
type, one or more signals are selected and a match pattern, match value or other conditions are
defined for each. All Boolean and Bus signals use the Pattern Search type and all other signals
(including those derived from Plug-ins), use the Sequential Search type.
Sequential searches allow a sequence of match conditions consisting of fields within frames
among a sequence of frames. Each field match can have a specific value or a "don't care" (Any)
value, and a specific skip count or a skip count of "Any". With the sequential search a very long
sequence, consisting of multiple wildcards (any Field, any Frame, any Field Value) and specific
frame or field skip counts and specific Fields and Field values, can be defined to locate the
proverbial "needle" in a very long "hay stack". Sequential searches also have the option of placing
the match marker at a specific point in the match sequence.
Pattern searches match a pattern across multiple signals at a single point of time in the capture.
When ALL specified signals and conditions match the search criteria, the time of the match
condition (or Match Point) will be centered in the window that has "focus". Any other windows that
are a member of the same Link Group, will also center on the match point. (see: Searching 188 ,
Link Groups 180 )
Details of each search type are explained in the following sections.
§ Sequential Searches
§ Pattern Searches 187
183
5.6.1.1.1 Sequential Searches
The Sequential search type is used by all Plug-ins or Parsed (decoded) signal types. This includes
all signals except Boolean and Bus signals (see: Define Searches 181 ).
This search type has a group of search terms (or criteria) that is specific to the chosen signal type,
and can perform a search sequence by adding additional terms. Terms can be added by using the
Copy or More buttons.
By changing the Mode (Field or Frame) to Fields, you can target the search to sequentially match
while ignoring frame boundaries. To look for a sequence of multiple frames, each having their own
field sequence match, select the Frame mode. If frame information is not present in the data, the
Mode will be limited to Field sequences.

184
Field Mode
The number of Field terms is unlimited and each term is labeled using ASCII characters. In the
image above, three field terms are visible (a., b., c. ). Using term 'a.' as an example, each option
is explained below.
Push Pin button - This identifies which point in the sequence will be marked as the match
time in the search results. When selected, the 'Push Pin' will appear blue, indicating the
search marker will be placed at the beginning of this specific match term. When de-selected,
it will appear white, meaning another term in the sequence has been selected for the marker
position. The first term in the sequence will be selected automatically if none are selected.
Skip and Skip Count - Skip options are "Any number of fields" or "Specified number of
fields". When set to "Any number of Fields", the search will ignore the skip count and continue
searching for the next field that matches the criteria. The search will continue to the end of the
captured data if necessary before reporting a 'no match'. However, when set to "Specified
number of Fields", the search will only ignore (and skip) the number of fields specified in the
skip count editor before looking for the next match. If the next term after the skip count does
not match, then the search reports a 'no match'. Setting the skip count to a value of "0"
instructs the search to analyze the very next field in sequence (Do Not Skip).
© 2017 TechTools
185
DigiView User's Guide
Field - Some Signal types will have many field identifiers that can be used for targeted
searching. The Field selection can be used to choose the specific field type to search. If the
field to consider for the match is not the type specified, then the result is a 'no match', even if
the value for the field matches the specified value. The field selection options for the built-in
Async Signal type are shown below.
Value to Match - Depending on the specific field type, 1 or more values can be specified for
the match. Some fields do not have any additional values, so the search is a 'match' if the
specified field is found (i.e. Parity Error above). Other fields may have several values within
the field. Each value is referenced in the value editors with a preceding "%". As shown above,
the 'DATA' field has 1 value, identified by "%1". Below is an example of the editor for the
DATA field.
The value to search for can be specified in Decimal, HEX, Binary or ASCII format as
demonstrated below.
Decimal - 77
HEX
- 0x4D
Binary - b1001101
ASCII - 'M'
An example of a Field with more than 1 value (from the SPI signal type):
Buttons - The three buttons on the bottom left of a field term are for deleting the current term
(-), adding a new term below the current one (+) or creating and adding a duplicate of the
current term (Copy).

Navigating and Analyzing the Data
186
Frame Mode
Frame mode uses the same logic as field mode but adds an additional layer of grouping if frame
information is present in the data. The number of frame terms is not limited and each frame is
labeled numerically, starting with "1".
Skip and Skip Count - The Skip and Skip Count parameters apply to Frames (a group of
fields) instead of fields. The Field match sequence within each frame is limited to the fields
bounded by framing data of the signal type. We do not limit the number of Field terms or skips
within a frame. However, If you specify a sequence that involves a a greater number of fields
than the number of fields available in the framed data, the search will fail.
Buttons - In frames, the Delete, Add and copy buttons are located at the upper right corner of
the frame term and have the same functions as those described for fields, but apply to the
frame. If you copy a frame, the new frame will be identical to the one copied, including all field
terms and their individual settings.

5.6.1.1.2 Pattern Searches
The Pattern search type is used for Boolean or Bus signal types (see: Define Searches
Boolean Signals 40 , Bus Signals 42 ).
181
,
This search type can be used to find a value of one signal or a pattern of values in multiple
signals, that lasts for a specified time period.
You can see in the "Fetch from 094D" search displayed above, that it will search for a pattern
consisting of values from three signals (ALE, PSEN, AD14-0) that lasts for a duration of more than
50 nanoseconds. If this condition is found in the captured data, the specified marker will be set to
the time when the match occurs. In the above example, this would be 50ns after the matching
pattern begins.
Match Duration: Determines whether to skip all packets until a match is found, or to skip the
number of packets specified in "Skip Count" and then see if the next packet is a match.
Duration Units The duration qualifiers can be in ns,us,ms or sec and can use REAL numbers
(1.23 us).
Signals: Select a signal from this list to "add" them to the search. Signals added to the search
are displayed below the signal selection box where the pattern to match can be edited.
Match Pattern Format The match patterns can be specified in decimal, hex or binary. To
indicate a HEX specification, precede the number with '0x'. To indicate BINARY, precede the
number with 'b'. Binary specifications allow '0','1' and 'X' (don't care) characters. HEX
specifications allow HEX digits (0-1,A-F) or 'X' for a nibble of don't care bits. Decimal
specifications must use only 0-9.

Searching
Search Button
Left clicking on a search button searches back in time (previous match.) Right clicking on a
search button searches forward in time (next match.) See 'Define Searches' 181 for details on
creating searches.
Invoking Searches
There are several methods of invoking a search. Each presents a slightly different way of
selecting the search and the target window, but they all perform the search in the same
manner.
If the search is configured to search 'from center time', then the search starts from the center
time of the FOCUSED window (possibly the last match). Otherwise the search starts from the
search's marker position (possibly the last match). In either case, the marker is positioned at
the location of the search match and then the FOCUSED window is centered on the marker. If
the window is part of a link group, then the entire link group is centered as well (see: Link
Groups 180 ). The center time of the FOCUSED window does not change if the search fails.
Regardless of how the search is invoked, we actually always run the DEFAULT search on the
FOCUSED windowed. We simply CHANGE the DEFAULT search or the FOCUSED window
before running the search in some cases. This creates a very consistent environment where
you can jump from one search button to another without surprises. The last invoked search is
always the current DEFAULT search and the window under the mouse is always the currently
FOCUSED window.
Local Search
Each Data Table, List and Waveform window has a local search button. When you click on a
window's local search button, that window becomes the FOCUSED window and then the search
is applied to it as usual (using this newly FOCUSED window).
Search Manger Searches
When you click on a search button in the search manager, the DEFAULT search is changed to
that button's search and then the search is performed as usual (using this new DEFAULT
search). However, the search will be performed on the Waveform View of the currently focused
Link Group. (see: Search Manager 188 )
5.6.3
Search Manager Window
The search manager window shows a list of all defined searches (see: Define Searches 181 ). It
also provides an easy method of executing or editing any of the searches. This is particularly
useful if you need to do a series of searches involving different search types.
To open the search manager, select the Open Search Manager button (highlighted above) from
the main toolbar. Only one search manager can be created. If it is already open, it will focus and
appear in front of any other windows. The Search manager can be docked anywhere if desired.
However, since it always displays a list of already defined searches, it can be closed and opened
as needed without losing any data.

Auto Search Windows
Auto Searches expand the normal search to a linked list of positions in the captured data that
meet the search criteria. Click on any line of the resulting list to scroll the matching data into view.
Auto Searches also have the ability to halt the analyzer, determine which captures to preserve and
which captures to discard based on the search result.
To create a new Auto Search window, select the Open Feature Window button (highlighted
above) from the main toolbar, then select Auto Search.
Main Auto Search Features
1. Automatically runs selected searches after each capture or capture history 133 load.
2. User settings allow for halting, saving or skip-saving the capture based on match counts.
3. Presents a list of matches and the count.
4. Clicking on a search match will scroll any Waveform View or Tabular view of the same Link
Group to the time marked by the search match.

Capture History Searching
The entire Capture History 133 can be searched forward and backward to find a capture with a
search result that matches the halt qualifier specified.
Selected Search
Any search that you have defined for this project will be listed in the search selection drop-down
box. Choose the search you want to use from this selection (see Searches 181 ,Searching 188 ).
Halt Qualifier
Select the Logic (>, <, =, <>, <=, >=) and enter the count for the search to match. Most of the time
you may be looking for any file that results in a single match or more and would set the logic to
">=" and the count to "1". However, you may be looking for the "odd" capture that has far fewer or
greater matches than the other captures so we have allowed for values up to 32 bits to be
specified for the count.
Include Start Position
This option controls whether the search includes the file at the current position or not. Check this
option to include the current position when the search begins (forward or backward). This box will
be set automatically if the selected search is changed or on any changes to the halt qualifier. This
option is automatically cleared when the search of a capture file results in a match, which saves
you the trouble of manually clearing it if you re-start the search from the matched position to
continue searching for additional captures that match.
Backward
This button starts the search from the current position and proceeds towards the oldest capture
until a match is found or the oldest capture has been searched. The file at the current position is
only searched when the "include start position" option is selected.
Forward
This button starts the search from the current position and proceeds towards the newest capture
position until a match is found or the newest capture has been searched. The file at the current
position is only searched when the "include start position" option is selected.

Exporting
The captured data can be exported to a file in ASCII format for further analysis or documenting
purposes. DigiView provides three export methods to choose from with each method having a few
unique features. These features are documented in the next three sections:
§ Exporting All Signal Data (Raw) 198
§ Exporting From List Windows 200
§ Exporting From Table Windows 202
Properties common to all three export methods are discussed below.
Time Range
Select the Starting time and Ending time of the data to export. You can select from several
predefined time points (i.e. Data Start, Data End, Trigger, Marker 3, Center Time, etc) or select
Custom to manually enter the time.
File
Below the Time Range options, the file name and path for the export file will be displayed. To
change the name or location, chose the Destination button (to the right of the filename). You can
chose any valid storage device for your system including a Network Drive, Floppy Disk, FLASH
Memory, etc.
Estimated Free Disk Space
The available space of the export destination is calculated and displayed here. The available
space will be calculated whenever the destination changes. While the export is in progress, this
will be updated to keep you informed of remaining space. If the available space becomes too
small for the remaining portion of the export, then the export will automatically finish without
exporting the rest of the data.
Required Disk Space
The amount of disk space required to hold the exported data will be displayed here. Since all
storage devices require a minimum amount of space to hold a file, the minimum file size will be
shown if the exported data is smaller. If the export size is very large, the background color of this
display will turn to yellow. If the export size exceeds the available space on the storage device,
the background color will turn to red. Even though the estimated size is larger than available
space, you can still perform the export which will automatically halt when disk space becomes
critical. The export size will be calculated whenever any option or the destination changes.

DigiView User's Guide
Progress indicator
The lower left portion of the Export dialog will display the progress of the export. The progress
display will indicate the number of bytes already exported, the percentage of the data already
exported and the number of bytes per second being written to the storage device.
Stop Button
The export can be canceled at any time by selecting the Stop button. All data exported up to the
point of cancellation will be available in the exported file.
Export Button
After selecting the desired export options, choose this button to begin the export. This button will
be disabled while an export is in progress.
Export+ Button
After selecting the desired export options, choose this button to export all Capture History files
from the current capture to the most recent capture. When exporting is completed, the current
capture is reloaded. This button will be disabled while an export is in progress.
Export++ Button
After selecting the desired export options, choose this button to export the entire Capture
History. When exporting is completed, the current capture is reloaded. This button will be
disabled while an export is in progress.
Close Button
To exit the Export window, choose this button. If an export is in progress, the export will be
canceled automatically.

Exporting All Signal Data
This export method can be selected from the Main menu (Menu->Export->UnDecoded Capture) and
provides a means of exporting the raw data of all defined signals. The available options let you
chose which signals to export, time format, numerical format, field separator, inclusion of line
numbers, inclusion of a timestamp and whether to use compression. (see: Exporting 196 )
The Exported Data Example area will be updated automatically to reflect any changes in export
options.
Timestamp
If the "Include Time Stamp" option is selected, the time field will be formatted as the absolute
time or (if set to Delta) as the time since the previous sample (or the last known sample after
the starting time). If the "Data Compression" option is set to OFF and this option is set to Delta,
then the time field will show the sample rate.
Numerical Format
This option determines the formatting for each signal that uses more than one channel (Boolean
© 2017 TechTools
199
DigiView User's Guide
signals will always be formatted as a '1' or '0'). This option will display the format setting of a
signal when a signal is selected. To change the format for a signal, first select the signal in the
Signal Selection area. If changes are allowed for the selected signal, then the format options will
"enable". Select the desired option.
Field Separator
Chose the character for separating each item on a line of exported data.
Include Line Numbers
Select this option to include a consecutive line number at the beginning of each line.
Include Time Stamp
Select this option to include the time of each exported sample.
Signal Selection
Check each signal to include in the export. The order of export is determined by the order in
which each signal is checked. To have the export order match the listed order, use the Clear All
button to clear all selections, then use the Select All button to select all the signals in the order
shown. To move a signal to the end of the export line, uncheck and then recheck the signal.
When a signal is highlighted with the mouse, its export format setting will be shown in the
Numerical Format option. This option can be changed by selecting the desired format (excluding
Boolean signals).
Data Compression
Setting this option to ON will greatly reduce the size of the export file. With compression on, the
redundant or "dead" periods of data will be excluded and only changes in the data will be
exported. If this option is set to OFF, then no data will be eliminated and all samples at the
maximum resolution will be exported. This could lead to very long exports with sizes up in the
Terabyte range.
Clear All Button
Use this button to "uncheck" all signals in the Signal Selection Area. Unchecked signals will be
excluded from the export.
Select All Button
Use this button to "check" all signals in the Signal Selection Area. All checked signals will be
included in the export.

Exporting from List Windows
This export method can be selected from the Main menu (Menu->Export->Table/Decoded List) or
directly from a Tabular View's menu. List Exports export the decoded data of higher level signals
(such as I2C), and will have a slightly different set of options that are specific to each signal type.
(see: Exporting 196 , Signal Types 35 , Tabular Views 176 )
The Exported Data Example area will be updated automatically to reflect any changes in export
options.
Numerical Format (Radix)
This option determines the formatting for each signal that uses more than one channel (Boolean
signals will always be formatted as a '1' or '0'). This option will display the format setting of the
signal in the list view being exported. To change the format for exporting, select the desired
option.
Field Separator
Chose the character for separating each item on a line of exported data.
Field Mode
Select this option to force each field to a new line when framing data is present. Uncheck this
option to output a frame of fields per line.
Include Field Names

Exporting from Table Windows
This export method can be selected from the Main menu (Menu->Export->Table/List-> choose a
Table) or directly from a Table Window's menu. Table Exports provide all the same options as the
"Export All" function, but will automatically include all columns of the table. This means you will not
have to select which signals to export, plus all channels of any signals that are "expanded" will also
be included in the export. This is the only export method that will export expanded channels. (see:
Exporting 196 , Export All 198 , Table Windows 173 )
Tables display and export signals in their "raw" data format. If you need to export the decoded data
of higher level signals (such as I2C), then the List Export should be used instead. (see: List Export
200 , I2C Signals 50 )
The Exported Data Example area will be updated automatically to reflect any changes in export
options.
Timestamp
If the "Include Time Stamp" option is selected, the time field will be formatted as the absolute
time or (if set to Delta) as the time since the previous sample (or the last known sample after
the starting time). If the "Data Compression" option is set to OFF and this option is set to Delta,
then the time field will show the sample rate.

Field Separator
Chose the character for separating each item on a line of exported data.
Include Line Numbers
Select this option to include a consecutive line number at the beginning of each line.
Include Time Stamp
Select this option to include the time of each exported sample.
Signal Selection
All Signals in the Table are automatically displayed in this area and "checked" for export. To
exclude a signal from the export, cancel the export, remove the signal from the Table, then
select export again. Optionally you could use the Export All function if you do not need to export
the channels of "Expanded" signals. (see: Export All 198 )
When a signal is highlighted with the mouse, its export format setting will be shown in the
Numerical Format option. This option can be changed by selecting the desired format (excluding
Boolean signals).
Data Compression
Setting this option to ON will greatly reduce the size of the export file. With compression on, the
redundant or "dead" periods of data will be excluded and only changes in the data will be

Printing and Saving Images
While analyzing the data, you may want to save a specific view to a graphic file or send it to a
printer. Both of these functions can be done from DigiView's Print Preview window. To open the Print
Preview window, select the "Print" or "Save Image" option from the menu of any window you want to
print.
To Print using the main menu select Main Menu-> Print and then select the window from the list.
To Save an Image using the main menu select Main Menu-> Save Image and then select the
window from the list.
Both lists include a selection for the Main Window and any feature window you have added to the
project. To print or save an image of just a waveform view, use the Waveform View's local menu.
After selecting what you want to print and opening the Print Preview window, you can switch
between printing and saving an image by clicking on the tabs at the top of the window. Most of the
options are the same between the two methods of output with the differences being the output size,
resolution and orientation.

Project Comment Options and Editor
The comment editor and options will be visible if you selected to include comments in the include
section.
The default comment options (shown above) are set so you can type as many lines as you want
and not worry about line spacing or formatting where each line ends. These are "Word Wrap
Output" enabled and Reserve space set to "By Line Count". With these two options set, the
output adjusts to accommodate the entire text in the output. For images the height grows by the
needed (or selected) space. On print output (which has a fixed printable area) the content is
reduced by the amount of space for the comment.
If you only want to reserve a specific portion of the output for comments (even without typing a
comment) set the "Reserve Space" option to the desired percentage (10% to 50%).
Subject - Type anything here and it will appear above the comment section in the output. The
example above has "Glitch Details" entered instead of the default of "Comments".
