Functional Overview
This discussion provides an overview of the main components of the platform.
For information about a specific module, refer to the user manual for that
module. Rear-panel remote connectors are described on page D–1 of this manual.
Important information on the power connector, line selector and fuse appears
under Configuration on page 1–3. Module rear-panel outputs are described in
the module user manuals.

Figure 2–1 shows a simplified block diagram of the TG 2000 Signal Generation
Platform.
System Control
As shown in Figure 2–1, the mainframe CPU coordinates front panel and remote
interface commands and uses that input to set up the modules, the clock, and the
optional AGL1 Genlock module. The CPU sends data and control messages over
the CPU bus to set up the generator modules to perform a function, such as load
a test signal into module memory or change the output configuration.
Disk Drive
The disk drive can be used to load or export signal sets, presets, sequences and
other data. The drive supports 1.44 Mbyte, MS-DOS format disks. Complete
signal sets for each module type are shipped with the module on 3.5 inch disks.
Refer to Appendix C for more information about the disk drive.
Remote Control
Most TG 2000 Signal Generation Platform front-panel control functions can be
remotely controlled using the RS-232, Parallel, or optional GPIB port. Ground
closure remote control can be accomplished using the Serial port. Refer to
Appendix D for more information about using the various remote interfaces.
A computer or other controller sends SCPI compatible commands to set up the
mainframe or a specific module. Each module must be individually set up using
its own set of commands. The mainframe and modules use some of the same
commands, but each also has unique commands. The SCPI command set for
each module is described in Section 3 of the module user manuals.

There are eleven module slots in the TG 2000 Signal Generation Platform. The
Clock and CPU modules are required for system operation and permanently
occupy two special slots (they must be installed in these slots). The black burst
module (BG1 Generator module) is also a standard component of the TG 2000
Signal Generation Platform, but you can remove it or replace it with another
module if desired. Without the black burst module, optional genlock or GPIB
modules, there is room for nine generator modules. You can use any combination
of different generator modules and/or multiples of the same generator module.
Generator modules, except the black burst module, contain NVRAM for storing
test signals. The test signals are initially loaded from the supplied disks or
through the parallel, GPIB, or RS-232 port into NVRAM. The signal that is
selected for output is loaded into fast memory on the module. The loaded signal
configures the module to immediately output the selected signal. The flexible
memory architecture allows one generator module to output signals stored on
another module of the same type. For example, installing four AVG1 Generator
modules provides four times the signal storage space, and all four modules have
equal access to this expanded memory space.
TG 2000 Signal Generation Platform User Manual
Functional Overview
Black Burst Module
The BG1 Black Burst Generator module is supplied as a standard accessory with
the platform. The module can generate one of these six black burst signals at a
time: NTSC with and without setup and color frame reference, and PAL with or
without color frame reference.
The module supplies the selected black burst signal on three rear-panel connectors. Additionally, the module can supply one of the system clocks on its
rear-panel Clock output. The module can be removed without affecting system
operation.
Battery Backup for
NVRAM
The platform uses a central rechargeable battery to maintain NVRAM data in the
mainframe and modules when AC power is not connected. The power supply
quick-charges the battery while the instrument power is on. When the instrument
is turned off using the front-panel On/Standby switch, the battery is tricklecharged. The battery is not recharged while the rear-panel power switch is off.
The battery power drain, with the rear-panel switch turned off, varies with the
type and number of modules installed. The power drain on the battery is low
enough to allow module memory to remain intact for many months. The length
of time that the memory remains intact is directly related to the type and number
of modules that are loaded. In the event of memory failure from power loss, the
test signals must be reloaded from the supplied disks or through a remote port
(and you should run self cal on all modules).
Clocks and Frame Reset
Signals
The CPU configures the Clock to generate the necessary clock frequencies and
frame reset pulses needed to support the video formats supplied by the active
modules. The TG 2000 Signal Generation Platform can supply different standard
formats (such as PAL and NTSC) at the same time, using the 27 MHz clock or
the two adjustable clocks and the two frame reset pulses. The internal reference
clock and frame synchronizes all modules driving compatible video formats.
Figure 2–2 shows how the clocks and frame reset pulses are generated.
The 27 MHz master clock synchronizes the clocks and frame reset pulses that
control module timing. The clock provides three high-speed clock signals; one at
27 MHz and two at rates from 10 MHz to 100 MHz. In addition, there are two
frame resets that allow different modules to operate in separate television
standards, such as PAL and NTSC. The clocks and frame reset pulses ensure that
all modules driving the same format remain synchronized.

External Reference
Genlock
An external reference may be used by the optional AGL1 Generator module to
lock on one of several video standards. All modules driving the format selected
for the AGL1 Generator module are locked to the external reference. Refer to the
AGL1 Analog Genlock Module User Manual for a list of the supported formats.
Timing References
The TG 2000 Signal Generation Platform supports internal or external references and signal delay relative to this reference. Video reference signals
synchronize the start of test signals of the same type, such as NTSC or PAL. For
using external references, the AGL1 module is required.
System delay and module timing delay are available to adjust for different signal
path delays in an operating environment. System delay uses the optional AGL1
module to lock the system to an external reference signal. Once the reference is
defined, you can add a common delay to all modules generating the same format
as the external reference.
Module timing delay, which is available with some modules, allows the delay of
one module from other modules generating a compatible format. Module timing
delay does not require an AGL1 module.

TG 2000 Signal Generation Platform User Manual
Functional Overview
Figure 2–3 shows the effects of the system delay and the individual module
delay. Note that the BG1 module is at time zero for intermodule timing because
it does not support module delay. In Figure 2–3, the BG1 and AVG1 output
signals are delayed 5 ms by the AGL1 module. The AVG1 is delayed an
additional 15 ms by the AVG1 system delay timer.
Refer to the AGL1 Analog Genlock Module User Manual for more information

Figure 2–4 shows how the module delay is implemented for the generator
modules that support it. They have the ability to delay the clock and frame reset
pulse for half a color frame. The delay is by a number of vertical lines plus a
horizontal delay up to the duration of one scan line. The delay is set in the
Module Timing window. Note that the variable system clocks also support
module delay.
TG 2000 Signal Generation Platform User Manual

Functional Overview
Most generator modules can be separately timed with respect to the system. This
is accomplished by applying a precise, variable delay to the system clocks and
frame resets as they enter the module. For conventional television, the adjustment range is effectively infinite, providing adjustment over a complete color
frame.
An adjustable trigger output is available on some modules to synchronize
external test equipment to any location in the test pattern. For a detailed
discussion of the system and module timing delay capabilities, refer to References on page 2–30.

Test Signals
The Module, Signal Sets and Test Signals buttons provide access to the output
signals. These buttons allow you to select a module, a signal set within the
module and a particular test signal. Figure 2–6 shows this test signal hierarchy.
The hierarchy provides for grouping signals of the same standard, such as NTSC,
under a descriptive name. Under the Signal Set name NTSC, for example, are
various test signals with descriptive names, such as “100% Color Bars.” When
you add or save signals, you should assign appropriate names for Signal Sets and
Test Signals to ensure that their format and function are clear.
Each module has a Module Parameters window to set parameters that apply to all
appropriate test signals from that module.
Each test signal has unique parameters controlled through the Active Signal
Parameters window. These include amplitude control for many parts of the video
signal. More information is supplied in the module user manuals.

Functional Overview
For instructions on loading signals into a module, refer to Disk Drive Procedures
on page C–1. For instructions on selecting test signals, refer to Selecting Test
Signals on page 2–38.
Shared Module Memory
A generator module can use the test signals stored in the memory of other
modules of the same type. For example, a newly installed AVG1 Generator
module can load and output signals stored in another AVG1 Generator module
already in the mainframe. The memory space in the two modules is combined to
provide twice the signal storage. The BG1 Generator module does not use this
shared memory structure; each BG1 Generator module contains the same set of
test signals.
When you remove a module, the signals stored in that module are no longer
available to the remaining modules. Before removing a module, copy all signals
for the module type to a disk (refer to Save Signals to Disk on page C–2). After
removing the module, you can load the desired signals from the disk into the
remaining modules, as space permits.

Brief Description of the
Front Panel Controls
The Navigation controls provide an alternative to touching display icons to select
them. Touching a display icon immediately activates the item, which often
means a delay while a signal loads. As an alternative, use the knob and cursor
buttons to move from item to item on the display without activating them. This
technique is known as browsing. Browsing lets you look through sets of test
signals, or other selections, without waiting for each to load. To activate a
browsed item, push the Select button.
The keypad provides a quick way to enter an exact quantity for a parameter.
Scale buttons, such as k (kilo) and M (mega), makes it easy to enter values.
The four function buttons at the right edge of the front panel provide a variety of
functions. The Front Panel Enable button enables and disables the front panel
controls and display. After the screen saver turns off the display and front panel,
use the Front Panel Enable button to enable them again. The Remote button lets
you set remote port parameters (refer to Appendix D). The Screen Contrast
button sets the knob to adjust the display contrast. The On/Standby button
powers up the TG 2000 Signal Generation Platform when the rear-panel power
switch is on.
You can use 3.5 inch disks to store signal sets, instrument settings or other files.
Refer to Using the Disk Drive on page C–1 for more information.
All of these controls are discussed in further detail in the following topics.

Programming Model
Specific conditions must exist before programming commands will affect the test
signal generated by a module.
Addressing Module Test
Signals
The following two steps must be performed before the test module will respond
to signal parameter commands.
1. Select the module to be addressed before executing any commands. Many of
the commands used by the TG 2000 Signal Generation Platform are shared
by several modules and will be accepted without a reported error.
2. Enable the module using the command. The output state
of the module must be enabled before test signal parameters can be changed.
Command Arguments
Many commands accept either string or numeric arguments. For example: a
boolean argument can either be “1” or “ON”.
Select signal parameter commands accept either a numeric value or one of the
following strings:
MINimum. Use this argument to query the minimum value or set the parameter
value to the minimum acceptable value.
TG 2000 Signal Generation Platform User Manual
3–1
Syntax
MAXimum. Use this argument to query the maximum value or set the parameter
value to the maximum acceptable value.
DEFault. Use this argument to query the default value or set the parameter value
to the default value.
UP. Use this argument to increase the parameter value one increment as defined
by the :STEP value.
DOWN. Use this argument to decrease the parameter value one increment as
defined by the :STEP value.
NOTE. If the TG 2000 Signal Generation Platform does not return a value in
response to a MIN or MAX query, then the values are undefined and an error
message is generated.
Argument Example
The following example demonstrates the effect of each of the arguments when
used with a step value.
1. :INSTrument:SELect AVG1:#" selects the analog video generator module
located in the slot number indicated by the “#” symbol.
2. :OUTPut:STATe ON enables the module and displays the loaded test signal.
NOTE. The :OUTPut must be “ON” before the following commands will have
any affect.
NOTE. :SOURce:MVIDeo:AMPLitude uses an argument that is the percent of
modulation.
3. :SOURce:MVIDeo:AMPLitude? DEF returns the default value of 100.0000.
4. :SOURce:MVIDeo:AMPLitude? MAX returns the maximum value of 127.0000
percent.
5. :SOURce:MVIDeo:AMPLitude DEFault sets the master video amplitude to
the default value.

SCPI Commands and Queries
SCPI is a standard created by a consortium that provides guidelines for remote
programming of instruments. These guidelines provide a consistent programming environment for instrument control and data transfer. This environment
uses defined programming messages, instrument responses, and data format
across all SCPI instruments, regardless of manufacturer. The TG 2000 Signal
Generation Platform uses a command language based on the SCPI standard.
The SCPI language is based on a hierarchical or tree structure (see Figure 3–1)
that represents a subsystem. The top level of the tree is the root node; it is
followed by one or more lower-level nodes.
STATe
OUTPut
Root node
CIRCle
Lower-level
nodes
DIAMeter POSition
Figure 3–1: Example of SCPI subsystem hierarchy
You can create commands and queries from these subsystem hierarchy trees.
Commands specify actions for the instrument to perform. Queries return
measurement data and information about parameter settings.
Creating Commands
SCPI commands are created by stringing together the nodes of a subsystem
hierarchy and separating each node by a colon.
In Figure 3–1, OUTPut is the root node and CIRCle, STATe, DIAMeter, and
POSition are lower-level nodes. To create a SCPI command, start with the root
node OUTPut and move down the tree structure adding nodes until you reach the
end of a branch. Most commands and some queries have parameters; you must
include a value for these parameters. If you specify a parameter value that is out
of range, the parameter will be set to a default value. The command descriptions,
which start on page 3–35, list the valid values for all parameters.
For example, OUTPut:CIRCle:STATe ON is a valid SCPI command created
from the hierarchy tree in Figure 3–1.
Creating Queries
3–4
To create a query, start at the root node of a tree structure, move down to the end
of a branch, and add a question mark. OUTPut:CIRCle:STATe? is an example of
a valid SCPI query using the hierarchy tree in Figure 3–1.

Parameter Types
Every parameter in the command and query descriptions is of a specified type.
The parameters are enclosed in brackets, such as <pattern>. The parameter type
is listed after the parameter and is enclosed in parentheses, for example,
(discrete). Some parameter types are defined specifically for the TG 2000 Signal
Generation Platform command set and some are defined by ANSI/IEEE

Abbreviating Commands,
Queries, and Parameters
You can abbreviate most SCPI commands, queries, and parameters to an
accepted short form. This manual shows these short forms as a combination of
upper and lower case letters. The upper case letters indicate the accepted short
form of a command. As shown in Figure 3–2, you can create a short form by
using only the upper case letters. The accepted short form and the long form are
equivalent and request the same action of the instrument.

NOTE. The numeric suffix of a command or query may be included in either the
long form or short form; the TG 2000 Signal Generation Platform will default to
“1” if no suffix is used. In Figure 3–2, the “3” of “VID3” indicates that the
command is directed to the third channel..
Chaining Commands and
Queries
You can chain several commands or queries together into a single message. To
create a chained message, first create a command or query, add a semicolon (;),
and then add more commands or queries and semicolons until you are done. If
the command following a semicolon is a root node, precede it with a colon (:).
Figure 3–3 illustrates a chained message consisting of several commands and
queries. The single chained message should end in a command or query, not a
semicolon. Responses to any queries in your message are separated by semicolons.
If a command fails, all following commands on the line are ignored. However, if
a valid command is followed by an invalid command, the valid command will be
executed.

The syntax for an IEEE 488.2 common command is an asterisk (*) followed by a
command and, optionally, a space and parameter value. The syntax for an
IEEE 488.2 common query is an asterisk (*) followed by a query and a question
mark. All of the common commands and queries are listed in the last part of the

Syntax
Constructed Mnemonics
Some header mnemonics specify one of a range of mnemonics. For example, a
channel mnemonic can be either CLOCk1, CLOCk2, or CLOCk3. You use these
mnemonics in the command just as you do any other mnemonic. For example,
there is a :SENS:ROSC:CLOC2:CAT? query, and there is also an
:SENS:ROSC:CLOC3:CAT? query. In the command descriptions, this list of
choices is abbreviated as CLOCk<n>. The value of <n> is the upper range of valid
suffixes. If the numeric suffix is omitted, the platform uses the default value of
“1”.
Block Arguments
Several of the platform’s commands use a block argument form:
Symbol
Meaning
<NZDig>
A non-zero digit character, in the range 1–9
<Dig>
A digit character, in the range 0–9
<DChar>
A character with the hex equivalent of 00 through FF
hexadecimal (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
<Dig> elements form a decimal integer that specifies how many <DChar>
elements follow.

TG 2000 Signal Generation Platform User Manual
Sequence Programming
Sequence programs enable the TG 2000 Signal Generation Platform to execute
routines using SCPI commands. The platform accepts sequences written using
the Tcl programming language.
Writing a Sequence Program
You can create sequence programs using Tcl programming language, and then
use the disk drive to load the sequences into the platform’s file system. Push the
Sequences button to access the downloading menus.You can also load sequences
through SCPI commands using the Program subsystem commands.
A sequence program can be very simple or it can contain many steps. When you
run a sequence, the program is interpreted by the platform’s Tcl parser; some Tcl
formatting information is required. A few points are mentioned here to show
how they are used in the samples. For more information on Tcl programming,
refer to Part 1 of Tcl and the Tk Toolkit: Addison-Wesley Publishing Company,
1994.
Comments in Tcl sequences are preceded by the # symbol as the first
nonblank character in the line. The # symbol appearing in the line at other
locations is treated as any other character.
SCPI commands that use double quote marks require an escape backslash
(\“string\”) in order to pass to SCPI using the Tcl scpi command.
SCPI commands should all be preceded with the string “scpi ”.
The Tcl parser checks the sequence statement to see if it is a supported Tcl
command. If the parser recognizes the command, it runs it as a Tcl command. If not, the parser looks for an *, a ?, or a : in the command lines to see
if it is a SCPI command. Putting the letters “scpi” in front of the SCPI
commands immediately tells the Tcl parser that it is a SCPI command.

Sequence Programming
Sample Program 1
This sample sequence program uses commands that change signals and displays.
Some control changes in the program are not required because the default setting
is correct for the sequence. Use the *RST command to set everything to its
default state or explicitly set them to avoid the possibility that the control is not
in the default setting.
The program loads and sequentially displays all of the signals available to an
AVG1 module installed in slot 8. The sequence consists of five sections:
chkCmd Subroutine
Set Parameters
Initialize the Instrument
Initialize the Module
Read the Signals
Display Each Signal
3–14
chkCmd subroutine
set parameters
initialize the instrument
read the signals
display each signal
The chkCmd subroutine loads each signal and checks for any system errors. The
subroutine tests for any failure errors and echoes them to the display.
The slot number and display time are set using the avgSlot and sleepTime
variables.
The SCPI command *CLS is used to initialize the instrument and clear any
pending errors.
Two module parameters not affected by the *CLS command are explicitly set to
ensure proper operation. The module is turned on first (so that it will accept
following commands) and then the circle overlay is turned off.
This routine uses the SCPI query :MMEMory:SIGNal:CATalog:ALL? to list all of
the signals that are available for the target module. The list of available signals is
loaded into siglist.
The signal display routine calls each of the signals identified in the previous
routine. The chkCmd subroutine is called to load and check each command. The
sleepTime parameter is used to control the period of time each signal is loaded.
The routine loops ten times and finishes by displaying “Test complete.”

Sample Program 2
This sample sequence program uses commands that change signals and displays.
Some control changes in the program are not required because the default setting
is correct for the sequence. Use the *RST command to set everything to its
default state or explicitly set them to avoid the possibility that the control is not
in the default setting.
The program loads and displays on command all of the signals available to an
AVG1 module installed in slot 8. The sequence consists of six sections:
Set Parameters
Select and Initialize
Read and List
set parameters
select and initialize the instrument
read and list the signals
user prompt
user feedback
display each signal
The slot number to be addressed is set.
The AVG1 is selected, enabled, and the circle overlay is disabled.
This routine uses the SCPI query :MMEMory:SIGNal:CATalog:ALL? to list all of
the signals that are available for the target module. The list of available signals is
loaded into siglist.
User Prompt
This routine reads the next signal name and formats it into an onscreen user
prompt.
User Feedback
When the user presses the QUIT button in the window the TG 2000 Signal
Generation Platform loads the signal.
Display the Signal
3–16
The signal display routine calls each of the signals identified in the previous
routine and checks for errors. The system then waits five seconds before
prompting the user to load the next signal. The routine finishes by displaying
“SequenceĂcompleted.”

Sequence Programming
Sample Program 3
You can use this sequence, together with the ground closure remote interface, to
remotely control the TG 2000 Signal Generation Platform.Information on using
the ground closure remote control is provided on page D–2.
This sample sequence file, named “gc.seq”, is provided on the TG2000 Utilities
disk that is included with this manual. The sequence can be modified to handle
any situation.
The diagram to create a ground closure control panel is shown in Figure D–4, on
page D–6 of this manual. Listed below are actions that are performed when each
of the eight functions is selected through the ground closure control panel.
Next Module
Sends the value 0 plus clock to the sequence, causing it to step to the next video
generator in the TG 2000 Signal Generation Platform. A four-tone audio
sequence tells you which module is active. The softer tone is low, and the louder
tone is high. For example, when the tones soft, soft, loud, loud are heard, it
corresponds to 0011 (a decimal value of three), indicating that the generator is in
slot three.
Next Signal Set
Sends the value 1 plus clock to the sequence, causing it to step to the next set of
video signals in the active generator module.
Next Signal
Sends the value 2 plus clock to the sequence, causing it to step to the next video
signal in the active generator module.
Previous Signal
Sends the value 0 plus clock to the sequence, causing it to step to the previous
video signal in the active generator module.
Internal Sync
Sets the AGL1 Generator module in slot 2 to use internal sync.
External Sync
Sets the AGL1 Generator module in slot 2 to use external sync.
Stop Sequence
Reset Sequence
Stops the sequence from monitoring the ground closure port. To restart the
sequence, use the Sequences window.
Sets the starting point for modules and signals to the following state:
Active module = first generator in the lowest slot.
Active signal set for each generator = first signal set in its list.
Active signal for each generator = first signal in the active signal set.

Sequence Programming
Running a Sequence
Sequences are stored in the N0:/sequence/" directory in the TG 2000 Signal
Generation Platform. The N0:" refers to slot number 0, which is the CPU
module.
NOTE. Although the CPU module is located in slot number 11 as labeled on the
rear panel, it is logically slot number 0.
Stored sequences can be called and started from the front panel, using the
Sequences button. To run a sequence from remote control using SCPI
commands, follow these steps:
1. Send PROG:CAT? to get a comma separated list of the available sequences.
2. Use the PROG:SEL:NAME <progname> command to select the sequence
program to run.
You can also use the PROG:EXPL:STAT <progname>,RUN command to start
the sequence that you specify. You can enter the sequence name without
quotes, unless a period is used in the name to separate the base from the
extension. If a file extension is used, then you must enter quotes to convey
the name to the platform, as shown in the following examples:
prog:expl:stat test1,run
prog:name "t_0044.tcl"
3. Use the PROG:SEL:STAT RUN command to start the named sequence.
4. Send PROG:SEL:STAT STOP to stop the running sequence if is is not self
terminating.
Autostart Files
The TG 2000 Signal Generation Platform automatically loads and runs a file
named autostrt" if it is in one of the following locations:
the N0:/sequence/" directory, or
the root directory of the A: drive
The platform checks for the autostrt" file, first on its disk drive, and then in
the N0:/sequence/" directory. The platform loads and runs the file when it is
found. If no autostrt" file is found, the platform waits for instructions from
the the front panel or remote control interface.
To stop the autostrt" sequence, touch Stop, and then choose Yes to All. You
can also stop the autostrt" sequence through remote control.

Common Commands
*RST
Use this command to restore factory settings (default values) to all modules. This
command also selects the output signal for each generator module, using the first
signal that is loaded in that module (or module type if you have more than one of
a given module). The CPU module is not affected by the *RST command. There
are no arguments.
If you use the *RST command, and then try to change the remote port, it may
lock up. To prevent this, either don’t use the *RST command or cycle power
before changing the remote port.

:MMEMory Commands
All signal movement or relocation within the generator modules or magnetic
drive is accomplished by copying all appropriate files (.dat and .sig) of the
named signal(s) to the new location. A *.dnl file is created when going outside
the normal environment; for example, when transferring a file from NVRAM to
3.5 inch disk. The signal tree is traversable and the use of wild cards permits
copying or storing individual signals or the entire module signal list.
Drive Nomenclature
The platform’s internal drives are named for the physical slot numbers of the
modules. For the CPU, use the physical slot number 11, and logical drive
number 0 (numeric zero). For slot number 10, use the letter A. Capitalize the
drive letter. For example, MMEM:CAT? “A:”.
The correct drive nomenclature is shown in the following table:

:SENSe Queries
Use these queries to query the clock for resource management and to determine
which generator modules are using which clock resources. The query responses
help you resolve resource conflicts by identifying which modules are using what
resources; you can then disable those modules that are not needed for the current
operation.
NOTE. The clock module must be selected with the INSTrument subsystem prior
to using these queries.

:STATus Commands
The STATus subsystem maintains the operating status of the instrument. There is
a bitmapped status tree that reflects the condition of the instrument. This allows
masking conditions and reading status nondestructively or destructively.
Each module is responsible for the contents of two registers:
OPERation:INSTrument:ISUMmary
QUEStionable:INSTrument:ISUMmary
These registers are fed into the appropriate OPERation:INSTrument and
QUEStionable:INSTrument summary bit.

OPERation
QUEStionable
Subnodes
The OPERation node covers areas of instrument operational events. This node
reports such items as signal settling, calibration, or running a sequence
The QUEStionable node covers areas of questionable conditions that exist within
the instrument. Questionable conditions might cause you to be unsure of the
quality of the generated signals.
Each node has a set of subnodes that query the contents, or control the involvement, of each bit.
ENABle selects which bits are active in reporting the status.
EVENt is a destructive query only of the status.
CONDition is a nondesctructive query only of the status.
PTRansition allows a status to become true on a positive transition of the
event.
NTRansition allows a status to become true on a negative transition of the
event.
MAP reassigns event reporting at the top level of the status hierarchy.
INSTrument. Both main nodes have this subnode that summarizes the
operational and questionable condition of the instrument. Each bit in these
two registers represents a slot in the platform. The summation of each
register will feed into bit 13 of its respective parent register.
GLCOsure determines the state of the lines of the ground closure port.
PRESet
All of the enable registers are set to TRUE so that they return to power-up
conditions.
QUEue
QUEue:ENABle enables certain events or error conditions to be reported. Values
that are not explicitly specified are not reported. STATus:QUEue[:NEXT?] is the
same as SYSTem:ERRor?.
Due to the repetitiveness of this subsystem, details are provided only for the
EVENt, CONDition, ENABle, PTRansition, NTRanstion, MAP, INSTrument,
and GCLOsure nodes. The syntax and examples do not include the full
command; refer to the Command Tree to derive that information. The following

Status and Events
The SCPI interface in the TG 2000 Signal Generation Platform includes a status
and event reporting system that enables the user to monitor crucial events that
occur in the platform. The platform is equipped with four registers and one
queue that conform to IEEE Std 488.2-1987. This section discusses these
registers and queues, along with status and event processing.
Registers
There are two main types of registers:
Status Registers, which store data relating to instrument status. This type of
register is set by the platform.
Enable Registers, which determine whether to set events that occur in the
platform to the appropriate bit in the status registers and event queues. You
can set this type of register.
Status Registers
There are five types of status registers:
Status Byte Register (SBR)
Standard Event Status Register (SESR)
Operational Register
Questionable Register
Instrument Summary Registers (ISR)
Read the contents of these registers to determine errors and conditions.
TG 2000 Signal Generation Platform User Manual
4–1
Status and Events
Status Byte Register
(SBR)
The SBR is made up of 8 bits. Bits 4, 5 and 6 are defined in accordance with
IEEE Std 488.2-1987 (see Figure 4–1 and Table 4–1). These bits are used to
monitor the output queue, SESR and service requests, respectively. The contents
of this register are returned when the *STB? query is used.

RQS (Request Service)/MSS (Master Status Summary). When the platform is
accessed using the GPIB serial poll command, this bit is called the Request
Service (RQS) bit and indicates to the controller that a service request has
occurred (the GPIB bus SRQ line is LOW). The RQS bit is cleared when the
serial poll ends.
When the platform is accessed using the *STB? query, this bit is called the
Master Status Summary (MSS) bit and indicates that the platform has issued a
service request for one or more reasons. The MSS bit is never cleared to 0 by
the *STB? query.

5
Event Status Bit (ESB). This bit indicates whether or not a new event has
occurred after the previous Standard Event Status Register (SESR) was
cleared or after an event readout was performed.

Execution Error (EXE). Indicates that an error occurred during the execution of
a command. Execution errors occur for one of the following reasons:
A value designated in the argument is outside the allowable range of the
platform, or is in conflict with the capabilities of the platform.
The command could not be executed properly because the conditions for
execution differed from those essentially required.
3
Device-Specific Error (DDE). An instrument error has been detected.
2
Query Error (QYE). Indicates that a query error has been detected by the
output queue controller. Query errors occur for one of the following reasons:
An attempt was made to retrieve messages from the output queue,
despite the fact that the output queue is empty or in pending status.
The output queue messages have been cleared despite the fact that they
have not been retrieved.

Status and Events
Operational Status
Register (OSB)
Questionable Status
Register (QSB)
Instrument Summary
Registers (OISR and
QISR)
Only bit 13 (OSB) of the Operational Status Register is used by the platform.
This bit indicates the status of the Operational Instrument Summary Register
(OISR). Use :STAT:OPER:COND? to perform a non-destructive query of this
register.
Only bit 13 (QSB) of the Questionable Status Register is used by the platform.
This bit indicates the status of the Questionable Instrument Summary Register
(QISR). Use :STAT:QUEST:COND? to perform a non-destructive query of this
register.
Both the Operational Register and Questionable Register receive status from
their Instrument Summary Registers (OISR and QISR). The OISR indicates
which slots are occupied in the platform. The QISR indicates which modules
have reported malfunctions during their power on diagnostics.
Use :STAT:QUES:INST:COND? or :STAT:OPER:INST:COND? to perform a
non-destructive query of these registers. The query will return an integer value
whose bits represent the status of each slot.
NOTE. The most significant bit (MSB) of each ISR is always set to “0”.
For example: given the following response to the :CAT:FULL? query:
"CPU:0","CLOCK:1","BG1:2","AGL1:3","AVG1:7","DVG1:8"
The response from the STAT:OPER:INST:COND? query will be 399. Converting
the decimal integer 399 to binary gives 110001111. Starting at the least
significant digit, this value indicates that slots 0, 1, 2, 3, 7, and 8 are occupied.
Enable Registers
There are two types of enable registers: the Event Status Enable Register
(ESER) and the Service Request Enable Register (SRER).
Each bit in these enable registers corresponds to a bit in the controlling status
register. By setting and resetting the bits in the enable register, the user can
determine whether or not events will be registered to the status register and
queue.
Event Status Enable
Register (ESER)
4–4
The ESER is made up of bits defined exactly the same as bits 0 through 7 in the
SESR (see Figure 4–3). Use this register to designate whether the SBR ESB bit
should be set when an event has occurred and whether the corresponding SESR
bit has been set.
TG 2000 Signal Generation Platform User Manual
Status and Events
To set the SBR ESB bit (when the SESR bit has been set), set the ESER bit
corresponding to that event. To prevent the ESB bit from being set, reset the
ESER bit corresponding to that event.
Use the *ESE command to set the bits of the ESER. Use the *ESE? query to
read the contents of the ESER.

Figure 4–3: The event status enable register (ESER)
Service Request Enable
Register (SRER)
The SRER is made up of bits defined exactly the same as bits 0 through 7 in the
SBR (see Figure 4–4). Use this register to determine which events will generate
service requests.
The SRER bit 6 cannot be set. Also, the RQS is not maskable.
The generation of a service request with the GPIB interface involves changing
the SRQ line to LOW and making a service request to the controller. The result
is that a status byte for which an RQS has been set is returned in response to
serial polling by the controller.
Use the *SRE command to set the bits of the SRER. Use the *SRE? query to
read the contents of the SRER. Bit 6 must normally be set to 0.

Status and Events
Queues
There are two types of queues in the status reporting system used in the
platform’s: output queues and event queues.
Output Queue
The output queue is a FIFO (first in, first out) queue and holds response
messages to queries, where they await retrieval. When there are messages in the
queue, the SBR MAV bit is set.
The output queue will be emptied each time a command or query is received, so
the controller must read the output queue before the next command or query is
issued. If this is not done, an error will occur and the output queue will be
emptied; however, the operation will proceed even if an error occurs.
Event Queue
4–6
The event queue is a FIFO queue and stores events as they occur in the platform.
If more than 32 events occur, event 32 will be replaced with event code –350
(“Queue Overflow”). You can retrieve the oldest error code and text using one of
the following queries:
:SYSTem:ERRor?
:STATus:QUEue[:NEXT]?
TG 2000 Signal Generation Platform User Manual
Status and Events
Status and Event Processing Sequence
The following outline lists the sequence for status and event processing, as
illustrated in Figure 4–5.
1. When an event occurs, the SESR bit corresponding to that event is set and
the event is placed in the event queue.
2. A bit corresponding to that event in the ESER is set.
3. The SBR ESB bit is set to reflect the status of the ESER.
4. When a message is sent to the output queue, the SBR MAV bit is set.
5. Setting either the ESB or MAV bits in the SBR sets the respective bit in the
SRER.
6. When the SRER bit is set, the SBR MSS bit is set and a service request is
generated when using the GPIB interface.

Status and Events
Messages
Tables 4–3 through 4–7 show the codes and messages used in the status and
event reporting system in the platform.
You can obtain event codes and messages using the queries :SYSTem:ERRor?
and :STATus:QUEue[:NEXT]?. These are returned in the following format:
<event code>,"<event message>"
Table 4–3 shows the messages generated when there is a syntax error in the
command.
Table 4–4 shows the messages generated when an error is detected while a
command is being executed.
Table 4–5 shows the messages generated when an internal instrument error is
detected. When this type of error occurs, it may be due to a hardware problem.
Table 4–7 shows the messages for system events. This type of message is
generated when the platform changes to a certain status.
Synchronizing Execution
Almost all SCPI commands are executed in the order in which they are sent from
the controller, and the execution of each command is completed in a short period
of time. However, some commands require a longer period of time to complete
execution. These commands are designed so that the next command to be sent is
executed without waiting for the previous command to be completed. In some
cases, a process executed by another command must first be completed before
these commands can be executed; in other cases, these commands must be
completed before the next command is executed.
All commands are executed in the sequence entered. The exception is...
:PROGram:WAIT.
Sequences are started with the :PROG:STATe command and the command
returns once the sequence has started. (The sequence runs in the background) If
you want to wait until the sequence is completed, use the :PROG:WAIT
command immediately after starting the sequence.
To synchronize execution, use the following commands:
*OPC
*OPC?
*WAI
4–8
TG 2000 Signal Generation Platform User Manual
Status and Events
Using the *WAI Command
The *WAI command is included to ensure compliance with the SCPI standard;
however, the operational model of this platform makes it an unnecessary
command.
Using the *OPC Command
The *OPC command sets the SESR OPC bit when all pending operations have
been completed. It is possible to synchronize execution by using this command
together with the serial poll or service request functions when using a GPIB
interface.
For example, the following command string will set the OPC bit to 1 on
completion of loading the test signal.
:MMEM:LOAD:SIGN 8,"AVG1/NTSC/COLORBAR/100% BARS";*OPC
Using the *OPC? Query
The *OPC? query writes an ASCII code “1” to the output queue when all
pending operations are completed. Synchronization can be performed using the
following procedure:
:MMEM:LOAD:SIGN 8,"AVG1/NTSC/COLORBAR/100% BARS";*OPC?
*OPC? waits for a “1” to be written to the output queue. In the event that the
system is waiting for data to be retrieved from the output queue, a time out may
occur before the data is written to the output queue.

Appendix C: Disk Drive
The TG 2000 Signal Generation Platform disk drive provides a way to load and
save signal sets and sequences for a module. It can also save all current settings,
called presets, for the mainframe and its modules to the disk. You use the disk
drive to load the signals into the module at installation time.
The disk drive uses 3.5 inch, 1.44 Mbyte, MS-DOS formatted disks. The disk
must be formatted before using it in the drive.
Supported File Types
The disk reads and writes the following file types:
Signal Sets. Files that serve as directories containing signal groups and, at the
lowest level, test signals. Signal set files have a .dnl suffix and may contain test
signals for more than one type of module. The SDP2000 Signal Development
Program creates and assigns signal sets. You can save signal sets from a module
to a disk.
Test Signals. Normally contained within the signal set files. Modified test
signals that you save, such as those with overlaid text or other adjusted parameters, are saved as *.sig files. These files contain only differences from the
original test signal (*.cmp). The *.sig files must accompany the original *.cmp
file.
Presets. Settings files stored in a special binary format that is unique to each
type of module. The settings can be saved to disk and restored later. They are
automatically saved to disk when you use the backup sequence (refer to
Instrument Backup on page E–8).
Sequences. Tcl files stored as ASCII text, and readable by any text editor. These
files contain a series of SCPI and Tcl commands that are entered using a text
editor. Sequence files have .seq suffix. Refer to page 3–13 for an example of a
Tcl sequence file.
You can specify a sequence file to run at power on. One way is to name it
AUTOSTRT and load it into the TG 2000 Signal Generation Platform. At power
on, the AUTOSTRT sequence is executed. Alternatively, place an AUTOSTRT
file on a disk and insert it in the TG 2000 Signal Generation Platform disk drive
before power on. It runs automatically at power on.

Appendix C: Disk Drive
Disk Drive Functions
When you push the Disk button, the Disk window opens, as shown below. The
four functions shown in the Disk window are described in the following pages.
Save Signals to Disk
Any signal that can be generated by a module can be saved on a disk. Save all
signals in a module to disk before removing the module, because modules lose
their signal memory 30 seconds after being removed from the mainframe.
To save test signal(s) to a disk, follow these steps:
1. Insert an MS-DOS formatted 3.5 inch disk into the TG 2000 Signal
Generation Platform disk drive. Ensure that the disk is not write protected.

Appendix D: Remote Interface
This section provides information on the remote communications, remote
connectors, and remote interface set up.
The TG 2000 Signal Generation Platform includes serial, parallel, and GPIB
ports. The serial port can be used for RS-232 or ground closure remote.
You can use the remote interfaces as follows:
Use SCPI commands for remote control of the instrument functions through
the RS-232, parallel, or GPIB port.
Control the instrument remotely using ground closure of the serial port in
combination with a Tcl sequence file.
Download test signals from the SDP2000 Signal Development Program
through the RS-232, parallel, or GPIB port.
Refer to Section 3, Syntax and Commands for SCPI programming information.
Refer to Sequence Programming on page 3–13 for information on modifying and
using sequences.
Remote Control using the RS-232, Parallel, or GPIB Interface
To use any of these interfaces for remote control, follow these steps:
1. Set up the appropriate interface parameters as described in Remote Interface
Setup on page D–7.
2. Connect the port to your computer or other controller. Refer to Remote
Connectors on page D–4.
3. Select the desired remote port through the Remote window.
4. Send SCPI commands and queries from your controller to the TG 2000
Signal Generation Platform. Refer to Section 3, Syntax and Commands for
SCPI programming information.
TG 2000 Signal Generation Platform User Manual
D–1
Remote Interface
Remote Control using the Ground Closure Interface
You can remotely control instrument functions through ground closure of the
9-pin serial connector. A set of 8 bits serve as input to the TG 2000 Signal
Generation Platform. The RS-232 interface is disabled while the ground closure
interface is enabled.
The best way to use the ground closure remote control is with a Tcl sequence that
continuously queries the ground closure port and branches according to its value.
Sample Program 3 on page 3–18 is a sample ground closure sequence. This
sequence, called gc.seq, is provided on the TG2000 Utilities disk that is included
with this manual. You modify this sequence to develop any desired response to a
ground closure. For information on modifying and using sequences, refer to
Sequence Programming on page 3–13.
You can use the SCPI query “:STATus:OPERation:GCLOsure?” on page 3–117
to obtain the status of the ground closure port (using the GPIB port, parallel port,
or sequence).
To use the ground closure remote, follow these steps:
1. Create a ground closure control panel and connect it to the rear-panel
connector as described on pages D–5 and D–6.
2. Through the Remote window, select Gnd Closure Enabled (this disables
the RS-232 interface).
3. Use the Sequences window to load the sequence named “gc.seq” from the
supplied TG2000 Utilities disk into the TG 2000 Signal Generation Platform
and run the sequence.
4. Use the ground closure control panel to ground each desired pin in turn.
5. If desired, you can lock out front-panel operation by touching Remote Only
in the Remote window.
6. Use a text editor to modify the sequence to suit your application, load the
modified sequence, and continue remote operation using the ground closure
control panel.
7. To stop the sequence, use the control panel to select Stop Sequence.
8. To enable the front panel controls again, push the Front-Panel Enable
button.
9. To enable the RS-232 interface again, select Gnd Closure Disabled in the
Remote window.

Remote Downloading of Signal Files
You can use the parallel, GPIB, or RS-232 interface to communicate with the
SDP2000 Signal Development Program. You can download signals from the
SDP2000 program to the generator modules. You can also display, on the
computer screen, the hierarchy of signals that are loaded in the generator
modules.
If your TG 2000 Signal Generation Platform is connected to a computer with the
SDP2000 Signals Development Program running, the program will display the
hierarchy of signal names that are already stored in the platform. This is useful
when remotely downloading new signals. More information is available in the
online help for the SDP2000 program.
To download *.dnl files from the SDP2000 program, follow these steps:
1. Connect the desired TG 2000 Platform port to a corresponding port on your
computer.
2. Select the appropriate port (RS-232, parallel, or GPIB) in the Remote
window.
3. Configure the port to match your computer.
4. In the SDP2000 program, set up the port to match the TG 2000 Platform port
configuration and select the appropriate port for communications. If the
communications are working properly, the program will display the
hierarchy of signal names that are already stored in the platform (you may
need to refresh the display).
The SDP2000 program will also tell you whether or not there is enough
space in the TG 2000 Signal Generation Platform for the selected download
file. If there is not enough room for the signals, you can copy some existing
signals to disk, and delete the copied signals to make room for the new
signals.
5. In the SDP2000 program, download the desired *.dnl file. The TGCOMM
(the communications portion of the SDP2000 program.) will open. The *.dnl
files will be downloaded to the TG 2000 Platform if there is enough memory
available.

To apply a ground closure, wire a switch and diode between each bit line and
ground. For example, connect a switch from pin 1 to pin 5. When this switch is
closed, it will apply a high in bit 0 of the :STATus:OPERation:GCLOsure?
response.
Figure D–4 shows how you can create binary values using individual switches
with the aid of diodes. Use small signal diodes, such as Tektronix part number
152-0141-02. Diodes are used to create AND gates. There are internal pull-up
resistors on each line.

Horizontal Blanking
Horizontal blanking is the entire time between the end of the active picture
time of one line and the beginning of active picture time of the next line. It
extends from the start of front porch to the end of back porch.
Horizontal Sync
Horizontal sync is the –300 mV (PAL) and –40 IRE (NTSC) pulse occurring
at the beginning of each line. This pulse tells the picture monitor to go back
to the left side of the screen and trace another horizontal line of picture
information.

(NTSC) or 5.5 MHz (PAL) IF that contains the sound information.
IRE
A unit equal to 1/140 of the peak-to-peak amplitude of the video signal,
which is typically one volt. The 0 IRE point is at the blanking level, with the
horizontal sync peak at –40 IRE and the 100% white peak at +100 IRE. IRE

domain in order to facilitate transmission or frequency-domain multiplexing.
See AM and FM for details.
Non-Linear Distortion
Refers to distortion that are amplitude-dependent.
NTSC
National Television System Committee. The organization that developed the
television standard currently in use in the United States, Canada and Japan.
Now generally used to refer to that standard.
PAL
Phase Alternate Line. Refers to one of the television systems used in Europe
and many other parts of the world. The phase of one of the color difference
signals alternates from line to line to help cancel out phase errors.
Quadrature AM
A process that allows two signals to modulate a single carrier frequency. The
two signals of interest Amplitude Modulate carrier signals which are the
same frequency but differ in phase by 90 degrees (hence the Quadrature
notation). The two resultant signals can be added together, and both signals
recovered at the other end, if they are also demodulated 90 degrees apart.
Quadrature Distortion
Distortion resulting from the asymmetry of sidebands used in vestigial
sideband television transmission. Quadrature distortion appears when
envelope detection is used, but can be eliminated by using a synchronous
demodulator.
RGB or GBR
Red, Green and Blue. The three primary colors sued in color television’s
additive color reproduction system. These are the three color components
generated by the camera and used by the picture monitor to produce a
picture.
R-Y
One of the color difference signals used in the NTSC and PAL systems,
obtained by subtracting luminance (Y) from the red camera signal (R). The
R-Y signals is also known as V.
Saturation
The property of color which relates to the proportion of white light in the
color. Highly saturated colors are vivid, while less saturated colors have
more white mixed in and therefore appear pastel. For example, red is highly
saturated, while pink is the same hue but much less saturated.
TG 2000 Signal Generation Platform User Manual
Glossary–5
Glossary
In signal terms, saturation is determined by the ratio between luminance
level and chrominance amplitude. “It should be noted that a vectorscope
does not display saturation: the length of the vectors represents chrominance
amplitude. In order to verify that the saturation of the colors in a color bar
signal is correct, you must check luminance amplitudes with a waveform
monitor in addition to observing the vectors.
Setup
In NTSC systems, video black is typically 7.5 IRE above the blanking level.
This 7.5 IRE level is referred to as the black setup level, or simply as setup.
Subcarrier
Refers to the high-frequency signal used for quadrature amplitude modulation of the color difference signals. The subcarrier frequency is 3,579,545 Hz
(NTSC) or 4,433,618.75 Hz (PAL).
Termination
In order to accurately send a signal through a transmission line, there must
be an impedance at the end which matches the impedance of the source and
of the line itself. Amplitude errors and reflections will otherwise result.
Video is a 75 W system, so a 75 W terminator must be put at the end of the
signal path.
Unmodulated
When referring to television test signals, this term refers to pulses and
pedestals which do not have high-frequency chrominance information added
to them.
Vectorscope
A specialized oscilloscope which demodulates the video signal and presents
a display of R–Y versus B–Y (V versus U). The angle and magnitude of the
displayed vectors are respectively related to hue and saturation.
Vertical Interval
The synchronizing information that appears between fields and tells the
picture monitor to go back to the top of the screen to begin another vertical
scan.
Y
Abbreviation for luminance.
Zero Carrier Reference
A pulse in the vertical interval which is produced by the demodulator to
provide a reference for evaluating depth of modulation.
