DPO3000 Series Programmer Manual
Getting Started
This manual explains the use of commands for remotely controlling your
oscilloscope. With this information, you can write computer programs to
perform functions, such as setting the front-panel controls, taking measurements,
performing statistical calculations, and exporting data for use in other programs.
Setting Up Remote Communications
You can remotely communicate between your oscilloscope and PC via the
Ethernet, USB, and, GPIB using the TEK-USB-488 Adapter.
Ethernet
If you are using Ethernet, start by connecting an appropriate Ethernet cable to the
Ethernet port (RJ-45 connector) on the rear panel of your oscilloscope. This
connects the oscilloscope to a 10/100 Base-T local area network.
To change the Ethernet settings on your oscilloscope, do the following:
1. On the front panel, push Utility.
2. Push Utility Page.
3. Select I/O with the Multipurpose knob.
4. Push Ethernet Network Settings.
5. On the side-bezel menu, if you are on a DHCP Ethernet network and using a
through cable, set DHCP/BOOTP to On.
6. If you are using a cross-over cable, set DHCP/BOOTP to Off, and set a hard
coded TCPIP address.
USB
If you are using USB, start by connecting an appropriate USB cable to the USB
2.0 high-speed device port on the rear panel of your oscilloscope.
DPO3000 Series Programmer Manual

Getting Started
With USB, the system automatically configures itself. To verify that the USB is
enabled:
1. On the front panel, push Utility.
2. Push Utility Page.
3. Select I/O with the Multipurpose knob.
4. Push USB, and verify that USB is enabled.
5. If USB is not enabled, push Enabled on the side-bezel menu.
After connection, the host will list the oscilloscope as a USB device with the
following parameters. (See Table 1-1.)

“USBTMC-USB488”
To use GPIB, start by connecting an appropriate USB cable to the USB 2.0
high-speed device port on the rear panel of your oscilloscope. Connect the other
end to the TEK-USB-488 Adapter host port. Then connect a GPIB cable from the
TEK-USB-488 Adapter to your PC.
DPO3000 Series Programmer Manual
Getting Started
Supply power to the Adapter in either of these two ways:
1. Use the optional 5 VDC power adapter connected to the 5 VDC power input
on the Adapter.
2. Use an appropriate USB cable connected to a powered USB host port on your
PC and the Device port on the TEK-USB-488 Adapter.
The oscilloscope has a USB 2.0 high-speed device port to control the oscilloscope
through USBTMC or GPIB with a TEK-USB-488 Adapter. The USBTMC
protocol allows USB devices to communicate using IEEE488 style messages.
This lets you run your GPIB software applications on USB hardware.
Before setting up the oscilloscope for remote communication using the electronic
(physical) GPIB interface, you should familiarize yourself with the following
GPIB requirements:
A unique device address must be assigned to each device on the bus. No two
devices can share the same device address.
No than 15 devices can be connected to any one line.
One device should be connected for every 6 feet (2 meters) of cable used.
No than 65 feet (20 meters) of cable should be used to connect devices to a bus.
At least two-thirds of the devices on the network should be powered on while
using the network.
Connect the devices on the network in a star or linear configuration. Do not
use loop or parallel configurations.
To function correctly, your oscilloscope must have a unique device address. The
default setting for the GPIB configuration is GPIB Address 1.
To change the GPIB address settings, do the following:
1. On the front panel, push Utility.
2. Push Utility Page.
3. Select I/O with the Multipurpose knob.
4. Push GPIB.
5. Enter the GPIB address on the side-bezel menu, using the multipurpose knob.
This will set the GPIB address on an attached TEK-USB-488 Adapter
The oscilloscope is now set up for bidirectional communication with your
controller.

DPO3000 Series Programmer Manual
Command Syntax
You can control the operations and functions of the oscilloscope through the
Ethernet port or the USB 2.0 device port using commands and queries. The
related topics listed below describe the syntax of these commands and queries.
The topics also describe the conventions that the oscilloscope uses to process
them. See the Command Groups topic in the table of contents for a listing of the
commands by command group, or use the index to locate a specific command.
Backus-Naur Form
Notation
This documentation describes the commands and queries using Backus-Naur
Form (BNF) notation. Refer to the following table for the symbols that are used.
Table 2-1: Symbols for Backus-Naur Form
Symbol

Meaning
=

Comment
Previous element(s) may be repeated
Command and Query Structure
Commands consist of set commands and query commands (usually called
commands and queries). Commands modify oscilloscope settings or tell the
oscilloscope to perform a specific action. Queries cause the oscilloscope to return
data and status information.
Most commands have both a set form and a query form. The query form of the
command differs from the set form by its question mark at the end. For example,
the set command ACQuire:MODe has a query form ACQuire:MODe?. Not all
commands have both a set and a query form. Some commands have set only and
some have query only.
Messages
A command message is a command or query name followed by any information
the oscilloscope needs to execute the command or query. Command messages
may contain five element types, defined in the following table.
DPO3000 Series Programmer Manual
2-1
Command Syntax
Table 2-2: Command Message Elements
Commands
Symbol
Meaning
<Header>
This is the basic command name. If the header ends with a question
mark, the command is a query. The header may begin with a colon
(:) character. If the command is concatenated with other commands,
the beginning colon is required. Never use the beginning colon with
command headers beginning with a star (*).
<Mnemonic>
This is a header subfunction. Some command headers have only one
mnemonic. If a command header has multiple mnemonics, a colon (:)
character always separates them from each other.
<Argument>
This is a quantity, quality, restriction, or limit associated with the header.
Some commands have no arguments while others have multiple
arguments. A <space> separates arguments from the header. A
<comma> separates arguments from each other.
<Comma>
A single comma is used between arguments of multiple-argument
commands. Optionally, there may be white space characters before
and after the comma.
<Space>
A white space character is used between a command header and the
related argument. Optionally, a white space may consist of multiple
white space characters.
Commands cause the oscilloscope to perform a specific function or change one of
the settings. Commands have the structure:
[:]<Header>[<Space><Argument>[<Comma> <Argument>]...]
A command header consists of one or more mnemonics arranged in a hierarchical
or tree structure. The first mnemonic is the base or root of the tree and each
subsequent mnemonic is a level or branch off the previous one. Commands at a
higher level in the tree may affect those at a lower level. The leading colon (:)
always returns you to the base of the command tree.
2-2
DPO3000 Series Programmer Manual
Command Syntax
Queries
Queries cause the oscilloscope to return status or setting information. Queries
have the structure:
[:]<Header>
[:]<Header>[<Space><Argument> [<Coma><Argument>]...]
You can specify a query command at any level within the command tree unless
otherwise noted. These branch queries return information about all the mnemonics
below the specified branch or level.
Headers
Use the HEADer command to control whether the oscilloscope returns headers as
part of the query response. If header is on, the query response returns command
headers, then formats itself as a valid set command. When header is off, the
response includes only the values. This may make it easier to parse and extract the
information from the response. The table below shows the difference in responses.
Table 2-3: Comparison of Header Off and Header On Responses
Query
Header Off
Header On
TIME?
14:30:00
:TIME “14:30:00”
ACQuire:NUMAVg?
100
:ACQUIRE:NUMAVG 100
Clearing the oscilloscope
You can clear the Output Queue and reset the oscilloscope to accept a new
command or query by using the selected Device Clear (DCL) function.
Command Entry
The following rules apply when entering commands:
You can enter commands in upper or lower case.
You can precede any command with white space characters. White space
characters include any combination of the ASCII control characters 00 through
09 and 0B through 20 hexadecimal (0 through 9 and 11 through 32 decimal).
The oscilloscope ignores commands consisting of any combination of white
space characters and line feeds.
DPO3000 Series Programmer Manual
2-3
Command Syntax
Abbreviating
You can abbreviate many oscilloscope commands. Each command in this
documentation shows the minimum acceptable abbreviations in capitals. For
example, you can enter the command ACQuire:NUMAvg simply as ACQ:NUMA
or acq:numa.
Abbreviation rules may change over time as new oscilloscope models are
introduced. Thus, for the most robust code, use the full spelling.
If you use the HEADer command to have command headers included as part
of query responses, you can further control whether the returned headers are
abbreviated or are full-length with the VERBose command.
Concatenating
You can concatenate any combination of set commands and queries using a
semicolon (;). The oscilloscope executes concatenated commands in the order
received.
When concatenating commands and queries, you must follow these rules:
1. Separate completely different headers by a semicolon and by the beginning
colon on all commands except the first one. For example, the commands
TRIGger:MODe NORMal and ACQuire:NUMAVg 8, can be concatenated
into the following single command:
TRIGger:MODe NORMal;:ACQuire:NUMAVg 8
2. If concatenated commands have headers that differ by only the last mnemonic,
you can abbreviate the second command and eliminate the beginning colon.
For example, you can concatenate the commands ACQuire:MODe ENVelope
and ACQuire:NUMAVg 8 into a single command:
ACQuire:MODe ENVelope; NUMAVg 8
The longer version works equally well:
ACQuire:MODe ENVelope;:ACQuire:NUMAVg 8
3. Never precede a star (*) command with a colon:
ACQuire:STATE 1;*OPC
Any commands that follow will be processed as if the star command was
not there so the commands, ACQuire:MODe ENVelope;*OPC;NUMAVg 8
will set the acquisition mode to envelope and set the number of acquisitions
for averaging to 8.
4. When you concatenate queries, the responses to all the queries are
concatenated into a single response message. For example, if the display
graticule is set to Full and the display style is set to dotsonly, the concatenated
query DISplay:GRAticule?;STYle:DOTsonly? will return the following.
If the header is on:
DISPLAY:GRATICULE FULL;:DISPLAY:STYLE:DOTSONLY 1
2-4
DPO3000 Series Programmer Manual
Command Syntax
If the header is off:
FULL;1
5. Set commands and queries may be concatenated in the same message. For
example,
ACQuire:MODe SAMple;NUMAVg?;STATE?
is a valid message that sets the acquisition mode to sample. The message then
queries the number of acquisitions for averaging and the acquisition state.
Concatenated commands and queries are executed in the order received.
Here are some invalid concatenations:
DISPlay:STYle:NORMal;ACQuire:NUMAVg 8 (no colon before ACQuire)
DISPlay:GRAticule FULL;:DOTSONLY OFF (extra colon before
DOTSonly. You could use DISPlay:DOTsonly OFF instead)
DISPlay:GRAticule FULL;:*TRG (colon before a star (*) command)
MATH:HORizontal:SCAle 1.0e-1;HORizontal:POSition 5.0el
(levels of the mnemonics are different; either remove the second use of
HORizontal: or place :MATH in front of HORizontal:POSition)
Terminating
This documentation uses <EOM> (End of Message) to represent a message
terminator.
Table 2-4: End of Message Terminator
Symbol
Meaning
<EOM>
Message terminator
The end-of-message terminator must be the END message (EOI asserted
concurrently with the last data byte). The last data byte may be an ASCII line
feed (LF) character.
This oscilloscope does not support ASCII LF only message termination. The
oscilloscope always terminates outgoing messages with LF and EOI.
Constructed Mnemonics
Some header mnemonics specify one of a range of mnemonics. For example, a
channel mnemonic can be CH1, CH2, CH3, or CH4. You use these mnemonics
in the command just as you do any other mnemonic. For example, there is a
CH1:POSition command, and there is also a CH2:POSition command. In the
command descriptions, this list of choices is abbreviated as CH<x>.

DPO3000 Series Programmer Manual
Command Syntax
Argument Types
Numeric
Many oscilloscope commands require numeric arguments. The syntax shows
the format that the oscilloscope returns in response to a query. This is also the
preferred format when sending the command to the oscilloscope though any of
the formats will be accepted. This documentation represents these arguments as
described below.
Table 2-10: Numeric Arguments
Symbol
Meaning
<NR1>
Signed integer value
<NR2>
Floating point value without an exponent
<NR3>
Floating point value with an exponent
<bin>
Digital data in binary format
Most numeric arguments will be automatically forced to a valid setting, by either
rounding or truncating,, when an invalid number is input, unless otherwise noted
in the command description.
Quoted String
Some commands accept or return data in the form of a quoted string, which is
simply a group of ASCII characters enclosed by a single quote (’) or double quote
("). The following is an example of a quoted string: "This is a quoted
string". This documentation represents these arguments as follows:
Table 2-11: Quoted String Argument
Symbol
Meaning
<QString>
Quoted string of ASCII text
DPO3000 Series Programmer Manual
2-7
Command Syntax
A quoted string can include any character defined in the 7-bit ASCII character
set. Follow these rules when you use quoted strings:
1. Use the same type of quote character to open and close the string. For
example: "this is a valid string".
2. You can mix quotation marks within a string as long as you follow the
previous rule. For example: "this is an ’acceptable’ string".
3. You can include a quote character within a string by repeating the quote. For
example: "here is a "" mark".
4. Strings can have upper or lower case characters.
5. If you use a GPIB network, you cannot terminate a quoted string with the
END message before the closing delimiter.
6. A carriage return or line feed embedded in a quoted string does not terminate
the string. The return is treated as another character in the string.
7. The maximum length of a quoted string returned from a query is 1000
characters.
Here are some invalid strings:
"Invalid string argument’ (quotes are not of the same type)
"test<EOI>" (termination character is embedded in the string)
Block
Several oscilloscope commands use a block argument form, as defined in the
table below.
Table 2-12: Block Argument
Symbol
Meaning
<NZDig>
A nonzero digit character in the range of 1–9
<Dig>
A digit character, in the range of 0–9
<DChar>
A character with the hexadecimal equivalent of 00 through FF (0
through 255 decimal)
<Block>
A block of data bytes defined as: <Block> ::=
{#<NZDig><Dig>[<Dig>...][<DChar>...] |#0[<DChar>...]<terminator>}
<NZDig> specifies the number of <Dig> elements that follow. Taken together,
the <NZDig> and <Dig> elements form a decimal integer that specifies how
many <DChar> elements follow.

Command Groups
This manual lists the Tektronix 3000 Series IEEE488.2 commands in two ways.
First, it presents them by functional groups. Then, it lists them alphabetically. The
functional group list starts below. The alphabetical list provides detail on each
command. (See page 2-53, Commands Listed in Alphabetical Order.)
Acquisition Command Group
Use the commands in the Acquisition Command Group to set up the modes and
functions that control how the oscilloscope acquires signals input to the channels,
and processes them into waveforms.
Using the commands in this group, you can do the following:
Start and stop acquisitions.
Control whether each waveform is simply acquired, averaged, or enveloped
over successive acquisitions of that waveform.
Set the controls or conditions that start and stop acquisitions.
Control acquisition of channel waveforms.
Set acquisition parameters.
Table 2-13: Acquisition Commands
Command
Description
ACQuire?

ACQuire:NUMACq?
Returns number of acquisitions that have
occurred
ACQuire:NUMAVg
Sets or returns the number of acquisitions for
an averaged waveform
ACQuire:STATE
Starts or stops the acquisition system
ACQuire:STOPAfter
Sets or returns whether the acquisition is
continuous or single sequence

Command Groups
Alias Command Group
Use the Alias commands to define new commands as a sequence of standard
commands. You may find this useful when repeatedly using the same commands
to perform certain tasks like setting up measurements.
Aliases are similar to macros but do not include the capability to substitute
parameters into alias bodies. The alias mechanism obeys the following rules:
The alias name must consist of a valid IEEE488.2 message unit, which may
not appear in a message preceded by a colon, comma, or a command or query
program header.
The alias name may not appear in a message followed by a colon, comma,
or question mark.
An alias name must be distinct from any keyword or keyword short form.
An alias name cannot be redefined without first being deleted using one of
the alias deletion functions.
Alias names do not appear in response messages.

File System Command Group
Use the commands in the File System Command Group to help you use USB
media. You can use the commands to do the following:
List the contents of a directory
Create and delete directories
Create, read, rename, or delete a file
Format media
When using these commands, keep the following points in mind:
File arguments are always enclosed within double quotes:
"E:/MYDIR/TEK00001.SET"
File names follow the non-case sensitive, MSDOS format:
[DRIVE:][\PATH\]filename
Path separators may be either forward slashes (/) or back slashes (\)
NOTE. Using back slash as a path separator may produce some unexpected
results, depending on how your application treats escaped characters. Many
applications recognize the sequence of back slash followed by an alphabetic
character as an escaped character, and, as such, interpret that alphabetic
character as a control character. For example, the sequence "\n" may be
interpreted as a newline character; "\t" may be interpreted as a tab character. To
ensure that this interpretation does not occur, you can use double back slashes.
For example, "E:\\testfile.txt".

Command Groups
Math Command Group
Use the commands in the Math Command Group to create and define a math
waveform. Use the available math functions to define your math waveform.
The math waveform you create depends on sources listed in the math expression.
If you change these sources, the math waveform you previously defined will be
affected.
Math expressions can be simple, containing no mathematical computation, such
as CH1, which specifies that a waveform shows the signal source of Channel 1.
Math expressions can also be complex, consisting of up to 128 characters and
comprising many sources, functions, and operands.
The acquisition of a live waveform can stop for several reasons: You can turn
off the channel, stop the waveform, or stop the trigger. When you turn off the
channel, math continues and data is acquired but is not displayed. When you
stop either the waveform or the trigger, the math calculation stops, and the last
math calculation performed is displayed.
When a live waveform update or reference waveform is altered, math waveforms
containing those waveforms as sources are also updated to reflect the changes.
Remember that sources must exist, but do not need to be displayed, to be used in
and to update math waveforms.

Measurement Command Group
Use the commands in the Measurement Command Group to control the automated
measurement system.
Up to four automated measurements can be displayed on the screen. In the
commands, these measurement readouts are named MEAS<x>, where <x> is the
measurement number.
In addition to the four displayed measurements, the measurement commands let
you specify an additional measurement, IMMed. The immediate measurement
has no front-panel equivalent. Immediate measurements are never displayed.
Because they are computed only when needed, immediate measurements slow the
waveform update rate less than displayed measurements.
Whether you use displayed or immediate measurements, use the VALue query to
obtain measurement results.
Measurement commands can set and query measurement parameters. You
can assign some parameters, such as waveform sources, differently for each
measurement. Other parameters, such as reference levels, have only one value,
which applies to all measurements.

Status and Error Command Group
Use the commands in the Status and Error Command Group to determine the
status of the oscilloscope and control events.
Several commands and queries used with the oscilloscope are common to all
IEEE488.2 compliant devices. The IEEE Std 488.2-1987 defines these commands
and queries. The common commands begin with an asterisk (*) character.

Trigger Command Group
Use the commands in the Trigger Command Group to control all aspects of
triggering for the oscilloscope.
There are two triggers: A and B. Where appropriate, this command set has parallel
construction between triggers.
You can set the A or B triggers to edge mode. Edge triggering lets you display
a waveform at or near the point where the signal passes through a voltage level
of your choosing.
You can also set A triggers to pulse, logic, or video modes. With pulse triggering,
the oscilloscope triggers whenever it detects a pulse of a certain width or height.
Logic triggering lets you logically combine the signals on one or channels. The
oscilloscope then triggers when it detects a certain combination of signal levels.
Video triggering enables you to trigger on the most common Standard Definition
video standards.

Command Groups
Waveform Transfer Command Group
Use the commands in the Waveform Transfer Command Group to transfer
waveform data points to and from the oscilloscope. Waveform data points are a
collection of values that define a waveform. One data value usually represents
one data point in the waveform record. When working with envelope waveforms,
each data value is either the minimum or maximum of a min/max pair.
Before you transfer waveform data, you must specify the data format, record
length, and waveform source or destination.
Data Formats
All data points for DPO models are signed integer format only. Valid data widths
for CH1-CH4, MATH, and REF1-REF4 are 1 and 2-byte widths. The valid data
widths for the digital collection is either 4 or 8-byte widths.
The oscilloscope can transfer waveform data in either ASCII or binary format.
You specify the format with the DATa:ENCdg command.
ASCII Data. ASCII data is represented by signed integer values. The range of the
values depends on the byte width specified. One byte wide data ranges from -128
to 127. Two byte wide data ranges from -32768 to 32767.
Each data value requires two to seven characters. This includes one to five
characters to represent the value, another character, if the value is negative, to
represent a minus sign, and a comma to separate the data points.
An example ASCII waveform data string may look like this:
CURVE<space>-110,-109,-110,-110,-109,-107,-109,-107,-106,
-105,-103,-100,-97,-90,-84,-80
NOTE. You can use ASCII to obtain a readable and easier to format output than
binary. However, the oscilloscope may require bytes to send the same values with
ASCII than with binary, reducing transmission speed.
The use of ASCII for waveform data transfer is inefficient. ASCII-formatted
Waveform (WAVFRM?) and Curve (CURVE?) queries, exceeding 1 M points,
are not supported.
Binary Data. Binary data is represented by signed integer or positive integer
values. The range of the values depends on the byte width specified. When the
byte width is one, signed integer data ranges from -128 to 127, and positive
integer values range from 0 to 255. When the byte width is two, the values range
from -32768 to 32767. and positive integer values range from 0 to 65,535.

Positive integer range
1
-128 to 127
0 to 255
2
32,768 to 32,767
0 to 65,535
The defined binary formats also specify the order in which the bytes are
transferred. The four binary formats are RIBinary, RPBinary, SRIbinary, and
SRPbinary.
RIBinary is signed integer where the most significant byte is transferred first, and
RPBinary is positive integer where the most significant byte is transferred first.
SRIbinary and SRPbinary correspond to RIBinary and RPBinary respectively but
use a swapped byte order where the least significant byte is transferred first. The
byte order is ignored when DATa:WIDth is set to 1.
Waveform Data and Record
Lengths
You can transfer multiple points for each waveform record. You can transfer a
portion of the waveform or you can transfer the entire record. You can use the
DATa:STARt and DATa:STOP commands to specify the first and last data points
of the waveform record.
When transferring data into the oscilloscope, you must first specify the record
length of the destination waveform record. You do this with the WFMInpre:NR_Pt
command. Next, specify the first data point within the waveform record. For
example, when you set DATa:STARt to 1, data points will be stored starting
with the first point in the record. The oscilloscope will ignore the value set by
DATa:STOP when reading in data. It will stop reading data when there is no data
to read or when it has reached the specified record length.
When transferring data from the oscilloscope, you must specify the first and last
data points in the waveform record. Setting DATa:STARt to 1 and DATa:STOP to
the record length will always return the entire waveform.
Waveform Data Locations
and Memory Allocation
Waveform Preamble
2-48
The DATa:SOUrce command specifies the waveform source when transferring a
waveform from the oscilloscope. You can only transfer one waveform at a time.
Waveforms sent to the oscilloscope are always stored in one of the reference
memory locations. Use the DATa:DESTination command to specify a reference
memory location.
Each waveform you transfer has an associated waveform preamble, which
contains information such as horizontal scale, vertical scale, and the other settings
in effect when the waveform was created. Refer to the individual WFMInpre and
WFMOutpre commands for information.

Arguments
ACQuire:NUMAVg, CURVe
SAMple specifies that the displayed data point value is the first sampled value
that is taken during the acquisition interval. In sample mode, all waveform data
has 8 bits of precision. You can request 16 bit data with a CURVe query but the
lower-order 8 bits of data will be zero. SAMple is the default mode.
PEAKdetect specifies the display of high-low range of the samples taken from a
single waveform acquisition. The high-low range is displayed as a vertical column
that extends from the highest to the lowest value sampled during the acquisition
interval. PEAKdetect mode can reveal the presence of aliasing or narrow spikes.
HIRes specifies Hi Res mode where the displayed data point value is the
average of all the samples taken during the acquisition interval. This is a form
of averaging, where the average comes from a single waveform acquisition. The
number of samples taken during the acquisition interval determines the number of
data values that compose the average.
AVErage specifies averaging mode, in which the resulting waveform shows an
average of SAMple data points from several separate waveform acquisitions. The
oscilloscope processes the number of waveforms you specify into the acquired
waveform, creating a running exponential average of the input signal. The number
of waveform acquisitions that go into making up the average waveform is set or
queried using the ACQuire:NUMAVg command.
ENVelope specifies envelope mode, where the resulting waveform shows the
PEAKdetect range of data points from every waveform acquisition.
Examples
ACQUIRE:MODE ENVELOPE sets the acquisition mode to display a waveform that
is an envelope of many individual waveform acquisitions.
ACQUIRE:MODE? might return:ACQuire:MODe AVERAGE indicating that

Each waveform has a vertical scale parameter. For a signal with constant
amplitude, increasing the Scale causes the waveform to be displayed smaller.
Decreasing the scale causes the waveform to be displayed larger.
Scale affects all waveforms, but affects channel waveforms differently from
other waveforms:
For channel waveforms, this setting controls the vertical size of the acquisition
window as well as the display scale. The range and resolution of scale
values depends on the probe attached and any other external factors you have

CURVe
Transfers waveform data to and from the oscilloscope in binary or ASCII format.
Each waveform transferred includes a waveform preamble which contains the
data format, scale, and associated information.
For analog waveforms, the CURVe? query transfers data from the oscilloscope.
The data source is specified by the DATa:SOUrce command. The first and last
data points are specified by the DATa:STARt and DATa:STOP commands.
The oscilloscope returns data from the last acquisition if the source is a channel
waveform that is being previewed. The data does not reflect the acquisition
preview parameters. The user should always follow acquisition parameter changes
with a single sequence OPC command prior to CURVe? to ensure the return data
reflects the new acquisition parameters.
The CURVe command transfers waveform data to the oscilloscope. The data
is stored in the reference memory location specified by DATa:DESTination,
starting with the data point specified by DATa:STARt. Only one waveform can
be transferred at a time. The waveform will only be displayed if the reference
is displayed.
NOTE. Transferring large volumes of data to or from the oscilloscope takes time.
ASCII waveform transfer is very inefficient.

set to 1 might return :CURVE 61,62,61,60,60,-59,-59,-58,-58,-59
NOTE. Curve data is transferred from the oscilloscope asynchronously, depending
on the length of the curve record. Such transfers may require several seconds
to complete. During this period, the oscilloscope will not respond to the user
controls. You can interrupt these asynchronous data transfers by sending a device
clear message to the oscilloscope or by interrupting the query with another
command or query. In order to verify that curve data has been completely
transferred, it is recommended that you follow such queries with an *ESR?
query to verify there are no error bits set. You can also check the event queue to
determine the cause of the error. If the error was caused by an interrupted query,
then the asynchronous data transfer was not complete when the *ESR? query was
sent. In such cases, it may be necessary to increase the program’s time-out value
to ensure that all data is transferred and read.

Commands Listed in Alphabetical Order
NOTE. When Persistence is set to Infinite, it does not mean that the brightness
of any pixel should never decrease. The brightness of a pixel is proportionally
dependent on the ratio between its intensity (which does NOT decrease at Infinite
Persistence) and the maximum value of intensity of any pixel on the screen. If a
particular pixel get hit less often than others, its brightness will decrease over
time. It will become less bright relative to the pixels that get hit often.
Group
Display
Syntax
DISplay:PERSistence {<NR3>|CLEAR|AUTO|MINImum|INFInite}
DISplay:PERSistence?
Arguments
<NR3> specifies the time of the persistence.
CLEAR resets the persist time count down and clears the display of acquired points.
INFInite displays waveform points until a control change resets the acquisition
system. When persistence is set to infinite, it does not mean that the brightness
of any pixel should never decrease. The brightness of a pixel is proportionally
dependent on the ratio between its intensity, which does NOT decrease at infinite
persistence, and the maximum value of intensity of any pixel on the screen. Thus,
if a particular pixel gets hit less often than others, its brightness will decrease over
time. It will become less bright relative to the pixels that get hit often.
AUTO specifies that the oscilloscope automatically determines the
best waveform persistence based on the value of waveform intensity
(DISPLAY:INTEnsITY:WAVEFORM)
MINImum specifies that the waveform persistence is set to the minimum value

FPAnel:TURN (No Query Form)
Simulates the action of turning a specified front-panel control knob.
When the front panel is locked, the front-panel button and multipurpose knob
operations are suspended. The FPAnel:PRESS and FPAnel:TURN commands
will also not work, and, they will not generate an error. You can work around
this by using the appropriate programmatic interface commands, instead of the
front-panel commands. For example, to set the trigger level to 50%, you could
use TRIGger:A SETLevel. To force a trigger, you could use TRIGger FORCe.

characters; the instrument ignores longer strings.
The message box size is set to fit the message. You can also set the message area
height and width using the MESSage:BOX command. The length of the message
that fits in the message area depends on the contents of the message because
the width of characters varies.
If the message exceeds the limits of the message box, either horizontally or
vertically, the portion of the message that exceeds the limits will not be displayed.

The message string itself is not altered. The entire message can be returned as a
query response regardless of what is displayed in the message box.
The message is left-justified, and is displayed on a single line starting with the
top most line in the window. A new line character can be embedded in the string
to position the message on multiple lines. You can also use white space and tab
characters to position the message within a line. Text which does not fit within
the message box is truncated. Defining a message box text string erases any
previously displayed text within the message box.
You can send a tab by transmitting a tab character (\t or \x09) followed characters
representing the most significant eight bits followed by significant eight bits of a
16-bit number. The number specifies the position relative to the left margin of
the message area. For example, to tab send TAB (\t or \x09), NUL (decimal 0),
and CR (decimal 13).
For example, using hexadecimal escape sequences, MESSAGE:SHOW
’\x09\x01\x17Hello’ when sent as a command would cause the ’Hello’ to be
displayed starting at pixel position 279 relative to the left margin set by the
MESSAGE:BOX command. If you want to display characters starting at position
279, then 279 = 0x0117; split the hexadecimal number into two characters 0x01
and 0x17 and send \x09\x01\x17.
Special characters which control decoration are two character sequences where the
first character is an escape (0x1b) and the second character is as described below.

The ESC (escape) character followed by the @ character turns inverse video on or
off and can be embedded in the message string. Example: “[email protected]@
ghi” specifies the string “abcdefghi” where the “def” portion is displayed in
inverse video.
Example: “abcESC#defESC)[email protected]” specifies the string “abcdefghi” where
the “def” portion appears in the channel 3 color (magenta) and the “ghi” portion
appears in the normal text color except it’s in inverse video.
An alternate way to enter characters is octal escape sequences. This consists of a
backslash followed by numerals in the standard C language printf fashion.
Another way to enter characters is \xnn where the nn is the hexadecimal value of
the character to display.
An advantage of these methods is that any controller program can be used.
Another advantage is it’s easy to access characters with the high bit set, that is,
those characters with a decimal value greater than 127.
An alternate way to enter certain characters is with a backslash followed by a
single character (following “standard” Unix) as described in the table below.
n
Newline (carriage return and line feed)
\
Backslash (\\ is required to get a backslash character)
t
Horizontal tab; the next 2 characters specify the pixel column to tab to
as explained earlier
If a backslash is followed by an undefined special character, the backslash is
ignored and the character following it is accepted as is.
NOTE. The use of any escape codes other than those described above may
produce unpredictable results.

(_) and the waveform ID (such as CH1, REF1, MATH) appended to the file
name(s).
Examples
SAVE:WAVEFORM CH1,REF1 saves the CH1 waveform in reference memory
location 1.
:SAVE:WAVEFORM:FILEFORMAT SPREADSHEET; :SAVE:WAVEFORM ALL,
"E:/test_folder/test1_all.csv" saves all displayed waveforms
(excluding serial bus waveforms) to E:/test_folder/test1_all.csv.
:SAVe:WAVEform:FILEFormat INTERNal; :SAVe:WAVEform ALL,
"E:/test_folder/test1" saves all displayed waveforms (excluding serial bus
waveforms) to individual files named E:/test_folder/test1_<wfm>.isf
(for example test1_CH1.isf).
SAVe:WAVEform:FILEFormat
Specifies or returns the file format for saved waveforms. Waveform header and
timing information is included in the resulting file of non-internal formats.
The oscilloscope saves DPO waveforms as a 500 x 200 matrix, with the first
row corresponding to the most recently acquired data. The values specified by
DATa:STARt and DATa:STOP determine the range of waveform data to output.
In the event that DATa:STOP value is greater than the current record length, the
current record length determines the last output value.

WFMInpre:NR_Pt, WFMOutpre:NR_Pt?
INTERNal specifies that waveforms are saved in an internal format, using a .isf
filename extension. These files can be recalled as reference waveforms. When this
argument is specified, the settings specified via the DATa:STARt and DATa:STOP
commands have no meaning as the entire waveform is saved.
SPREADSheet specifies that waveform data is saved in a format that contains
comma delimited values. These waveform data files are named using the .csv
filename extension. Saving waveforms in CSV format enables spreadsheet
programs to import the data.
Examples
SAVE:WAVEFORM:FILEFORMAT INTERNAL specifies that the internal file format
is the format used for saving waveforms.
SAVE:WAVEFORM:FILEFORMAT? might return :SAVE:WAVEFORM:FILEFORMAT
INTERNAL indicating that waveforms are saved using the internal format.
SAVe:WAVEform:GATIng
Specifies whether save waveform operations should save the entire waveform
(NONe) or a specified portion of the waveform.

Arguments
CURSors turns on cursors and the gates are the waveform record points at the
cursor positions.
NONe saves the entire waveform.
SCREEN, if zoom is on, the gates are the start and end waveform record points of
the zoom (upper) graticule, otherwise the gates are the start and end waveform
record points of the main graticule.
Examples

SAVE:WAVEFORM:GATING CURSors specifies that, when the waveform gating
is set to cursors, save waveform operations should save the waveform points
between the cursors. If cursors are turned off, waveform gating automatically
reverts to NONE.

SET? (Query Only)
Returns the commands that list the oscilloscope settings except for configuration
information for the calibration values, the WFMInpre? query, and the

command headers, regardless of the setting of the HEADer command. This is
because the returned commands are intended to be sent back to the oscilloscope as
a command string. The VERBose command can still be used to specify whether
the returned headers should be abbreviated or full-length.

Status and Events
The oscilloscope provides a status and event reporting system for the Ethernet,
GPIB (with the TEK-USB-488 Adapter), and USB interfaces. This system
informs you of certain significant events that occur within the oscilloscope.
The oscilloscope status handling system consists of five 8-bit registers and two
queues for each interface. The remaining Status subtopics describe these registers
and components. They also explain how the event handling system operates.
Registers
Overview
The registers in the event handling system fall into two functional groups:
Status Registers contain information about the status of the oscilloscope.
They include the Standard Event Status Register (SESR).
Enable Registers determine whether selected types of events are reported to
the Status Registers and the Event Queue. They include the Device Event
Status Enable Register (DESER), the Event Status Enable Register (ESER),
and the Service Request Enable Register (SRER).
Status Registers
The Standard Event Status Register (SESR) and the Status Byte Register (SBR)
record certain types of events that may occur while the oscilloscope is in use.
IEEE Std 488.2-1987 defines these registers.
Each bit in a Status Register records a particular type of event, such as an execution
error or message available. When an event of a given type occurs, the oscilloscope
sets the bit that represents that type of event to a value of one. (You can disable
bits so that they ignore events and remain at zero. See Enable Registers). Reading
the status registers tells you what types of events have occurred.
The Standard Event Status Register (SESR). The SESR records eight types of
events that can occur within the oscilloscope. Use the *ESR? query to read the
SESR register. Reading the register clears the bits of the register so that the
register can accumulate information about new events.
NOTE. TekVISA applications use SESR bit 6 to respond to any of several events,
including some front panel actions.

is complete. This bit is set when all pending operations
complete following an *OPC command.
The Status Byte Register (SBR). Records whether output is available in the Output
Queue, whether the oscilloscope requests service, and whether the SESR has
recorded any events.
Use a Serial Poll or the *STB? query to read the contents of the SBR. The bits in
the SBR are set and cleared depending on the contents of the SESR, the Event
Status Enable Register (ESER), and the Output Queue. When you use a Serial
Poll to obtain the SBR, bit 6 is the RQS bit. When you use the *STB? query to
obtain the SBR, bit 6 is the MSS bit. Reading the SBR does not clear the bits.

Enable Registers
DESER, ESER, and SRER allow you to select which events are reported to the
Status Registers and the Event Queue. Each Enable Register acts as a filter to a
Status Register (the DESER also acts as a filter to the Event Queue) and can
prevent information from being recorded in the register or queue.
Each bit in an Enable Register corresponds to a bit in the Status Register it
controls. In order for an event to be reported to a bit in the Status Register, the
corresponding bit in the Enable Register must be set to one. If the bit in the Enable
Register is set to zero, the event is not recorded.
Various commands set the bits in the Enable Registers. The Enable Registers and
the commands used to set them are described below.
The Device Event Status Enable Register (DESER). This register controls which
types of events are reported to the SESR and the Event Queue. The bits in the
DESER correspond to those in the SESR.
Use the DESE command to enable and disable the bits in the DESER. Use the
DESE? query to read the DESER.
Figure 3-3: The Device Event Status Enable Register (DESER)
The Event Status Enable Register (ESER). This register controls which types of
events are summarized by the Event Status Bit (ESB) in the SBR. Use the *ESE
command to set the bits in the ESER. Use the *ESE? query to read it.
Figure 3-4: The Event Status Enable Register (ESER)
The Service Request Enable Register (SRER). This register controls which bits
in the SBR generate a Service Request and are summarized by the Master Status
Summary (MSS) bit.
DPO3000 Series Programmer Manual
3-3
Status and Events
Use the *SRE command to set the SRER. Use the *SRE? query to read the
register. The RQS bit remains set to one until either the Status Byte Register is
read with a Serial Poll or the MSS bit changes back to a zero.
Figure 3-5: The Service Request Enable Register (SRER)
*PSC Command
The *PSC command controls the Enable Registers contents at power-on. Sending
*PSC 1 sets the Enable Registers at power on as follows:
DESER 255 (equivalent to a DESe 255 command)
ESER 0 (equivalent to an *ESE 0 command)
SRER 0 (equivalent to an *SRE 0 command)
Sending *PSC 0 lets the Enable Registers maintain their values in nonvolatile
memory through a power cycle.
NOTE. To enable the PON (Power On) event to generate a Service Request, send
*PSC 0, use the DESe and *ESE commands to enable PON in the DESER and
ESER, and use the *SRE command to enable bit 5 in the SRER. Subsequent
power-on cycles will generate a Service Request.
Queues
The *PSC command controls the Enable Registers contents at power-on. Sending
*PSC 1 sets the Enable Registers at power on as follows:
Output Queue
The oscilloscope stores query responses in the Output Queue and empties this
queue each time it receives a new command or query message after an <EOM>.
The controller must read a query response before it sends the next command (or
query) or it will lose responses to earlier queries.
CAUTION. When a controller sends a query, an <EOM>, and a second query,
the oscilloscope normally clears the first response and outputs the second while
reporting a Query Error (QYE bit in the ESER) to indicate the lost response. A
fast controller, however, may receive a part or all of the first response as well. To
avoid this situation, the controller should always read the response immediately
after sending any terminated query message or send a DCL (Device Clear) before
sending the second query.
3-4
DPO3000 Series Programmer Manual
Status and Events
Event Queue
The Event Queue stores detailed information on up to 33 events. If than 32
events stack up in the Event Queue, the 32nd event is replaced by event code
350, "Queue Overflow."
Read the Event Queue with the EVENT? query (which returns only the event
number), with the EVMSG? query (which returns the event number and a text
description of the event), or with the ALLEV? query (which returns all the event
numbers along with a description of the event). Reading an event removes it
from the queue.
Before reading an event from the Event Queue, you must use the *ESR? query to
read the summary of the event from the SESR. This makes the events summarized
by the *ESR? read available to the EVENT? and EVMSG? queries, and empties
the SESR.
Reading the SESR erases any events that were summarized by previous *ESR?
reads but not read from the Event Queue. Events that follow an *ESR? read are
put in the Event Queue but are not available until *ESR? is used again.
Event Handling Sequence
The figure below shows how to use the status and event handling system. In the

Status and Events
Figure 3-6: Status and Event Handling Process
When an event occurs, a signal is sent to the DESER (1). If that type of event
is enabled in the DESER (that is, if the bit for that event type is set to 1), the
appropriate bit in the SESR is set to one, and the event is recorded in the Event
Queue (2). If the corresponding bit in the ESER is also enabled (3), then the
ESB bit in the SBR is set to one (4).
When output is sent to the Output Queue, the MAV bit in the SBR is set to one (5).
When a bit in the SBR is set to one and the corresponding bit in the SRER
is enabled (6), the MSS bit in the SBR is set to one and a service request is
generated (7).

Synchronization Methods
Overview
Although most commands are completed almost immediately after being received
by the oscilloscope, some commands start a process that requires time. For
example, once a single sequence acquisition command is executed, depending
upon the applied signals and trigger settings, it may take a few seconds before the
acquisition is complete. Rather than remain idle while the operation is in process,
the oscilloscope will continue processing other commands. This means that some
operations will not be completed in the order that they were sent.
Sometimes the result of an operation depends on the result of an earlier operation.
A first operation must complete before the next one is processed. The oscilloscope
status and event reporting system is designed to accommodate this process.
The Operation Complete (OPC) bit of the Standard Event Status Register (SESR)
can be programmed to indicate when certain oscilloscope operations have
completed and, by setting the Event Status Enable Register (ESER) to report
OPC in the Event Status Bit (ESB) of the Status Byte Register (SBR) and setting
the Service Request Enable Register (SRER) to generate service request upon a
positive transition of the ESB, a service request (SRQ) interrupt can be generated
when certain operations complete as described in this section.
The following oscilloscope operations can generate an OPC:

Status and Events
For example, a typical application might involve acquiring a single-sequence
waveform and then taking a measurement on the acquired waveform. You could
use the following command sequence to do this:
/** Set up conditional acquisition **/
ACQUIRE:STATE OFF
SELECT:CH1 ON
HORIZONTAL:RECORDLENGTH 1000
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/** Acquire waveform data **/
ACQUIRE:STATE ON
/** Set up the measurement parameters **/
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT: IMMED:SOURCE CH1
/** Take amplitude measurement **/
MEASUREMENT: MEAS1:VALUE
The acquisition of the waveform requires extended processing time. It may not
finish before the oscilloscope takes an amplitude measurement (see the following
figure). This can result in an incorrect amplitude value.
Figure 3-7: Command Processing Without Using Synchronization
To ensure the oscilloscope completes waveform acquisition before taking the
measurement on the acquired data, you can synchronize the program.
Figure 3-8: Processing Sequence With Synchronization
You can use four commands to synchronize the operation of the oscilloscope with
your application program: *WAI, BUSY, *OPC, and *OPC
Using the *WAI Command
3-8
The *WAI command forces completion of previous commands that generate
an OPC message. No commands after the *WAI are processed before the OPC
message(s) are generated
DPO3000 Series Programmer Manual
Status and Events
The same command sequence using the *WAI command for synchronization
looks like this:
/* Set up conditional acquisition */
ACQUIRE:STATE OFF
SELECT:CH1 ON
HORIZONTAL:RECORDLENGTH 1000
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Acquire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
/* Wait until the acquisition is complete before taking
the measurement*/
*/
*WAI
/* Take amplitude measurement */
MEASUREMENT:IMMED:VALUE
The controller can continue to write commands to the input buffer of the
oscilloscope, but the commands will not be processed by the oscilloscope until
all in-process OPC operations are complete. If the input buffer becomes full,
the controller will be unable to write commands to the buffer. This can cause a
time-out.
Using the BUSY Query
The BUSY? query allows you to find out whether the oscilloscope is
busy processing a command that has an extended processing time such as
single-sequence acquisition.
The same command sequence, using the BUSY? query for synchronization, looks
like this:
/* Set up conditional acquisition */
ACQUIRE:STATE OFF
SELECT:CH1 ON
HORIZONTAL:RECORDLENGTH 1000
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Acquire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
/* Wait until the acquisition is complete before taking
the measurement */
While BUSY keep looping
DPO3000 Series Programmer Manual
3-9
Status and Events
/* Take amplitude measurement */
MEASUREMENT:IMMED:VALUE
This sequence lets you create your own wait loop rather than using the *WAI
command. The BUSY? query helps you avoid time-outs caused by writing too
many commands to the input buffer. The controller is still tied up though, and
the repeated BUSY? query will result in bus traffic.
Using the *OPC Command
If the corresponding status registers are enabled, the *OPC command sets the
OPC bit in the Standard Event Status Register (SESR) when an operation is
complete. You achieve synchronization by using this command with either a
serial poll or service request handler.
Serial Poll Method: Enable the OPC bit in the Device Event Status Enable
Register (DESER) and the Event Status Enable Register (ESER) using the DESE
and *ESE commands.
When the operation is complete, the OPC bit in the Standard Event Status Register
(SESR) will be enabled and the Event Status Bit (ESB) in the Status Byte Register
will be enabled.
The same command sequence using the *OPC command for synchronization with
serial polling looks like this:
/* Set up conditional acquisition */
ACQUIRE:STATE OFF
SELECT:CH1 ON
HORIZONTAL:RECORDLENGTH 1000
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Enable the status registers */
DESE 1
*ESE 1
*SRE 0
/* Acquire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
/* Wait until the acquisition is complete before taking the
measurement.*/
*OPC
While serial poll = 0, keep looping
/* Take amplitude measurement */
MEASUREMENT:IMMED:VALUE
This technique requires less bus traffic than did looping on BUSY.

DPO3000 Series Programmer Manual
Status and Events
Service Request Method: Enable the OPC bit in the Device Event Status Enable
Register (DESER) and the Event Status Enable Register (ESER) using the DESE
and *ESE commands.
You can also enable service requests by setting the ESB bit in the Service Request
Enable Register (SRER) using the *SRE command. When the operation is
complete, the oscilloscope will generate a Service Request.
The same command sequence using the *OPC command for synchronization
looks like this
/* Set up conditional acquisition */
ACQUIRE:STATE OFF
SELECT:CH1 ON
HORIZONTAL:RECORDLENGTH 1000
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Enable the status registers */
DESE 1
*ESE 1
*SRE 32
/* Acquire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
/* Wait until the acquisition is complete before taking the
measurement*/
*OPC
The program can now do different tasks such as talk to other devices. The SRQ,
when it comes, interrupts those tasks and returns control to this task.
/* Take amplitude measurement */
MEASUREMENT:IMMED:VALUE
This technique is efficient but requires sophisticated programming.
Using the *OPC? Query
The *OPC? query places a 1 in the Output Queue once an operation that generates
an OPC message is complete. A time out could occur if you try to read the output
queue before there is any data in it.
The same command sequence using the *OPC? query for synchronization looks
like this:
/* Set up conditional acquisition */
ACQUIRE:STATE OFF
SELECT:CH1 ON
HORIZONTAL:RECORDLENGTH 1000
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
DPO3000 Series Programmer Manual
3-11
Status and Events
/* Acquire waveform data */

MEASUREMENT:IMMED:SOURCE CH1

*OPC
Wait for read from Output Queue.
/* Take amplitude measurement */
MEASUREMENT:IMMED:VALUE
This is the simplest approach. It requires no status handling or loops. However,
you must set the controller time-out for longer than the acquisition operation.
Messages
The information contained in the topic tabs above covers all the programming
interface messages the oscilloscope generates in response to commands and
queries.
For most messages, a secondary message from the oscilloscope gives detail about
the cause of the error or the meaning of the message. This message is part of the
message string and is separated from the main message by a semicolon.
Each message is the result of an event. Each type of event sets a specific bit in the
SESR and is controlled by the equivalent bit in the DESER. Thus, each message
is associated with a specific SESR bit. In the message tables, the associated SESR
bit is specified in the table title, with exceptions noted with the error message text.
No Event
The following table shows the messages when the system has no events or status
to report. These have no associated SESR bit.
