TG8000 syntax
This section contains information on the Standard Commands for Programmable
Instruments (SCPI) and IEEE 488.2 Common Commands you can use to program
your TG8000. The information is organized in the following subsections:
Programming Model - This subsection provides information on programming
prerequisites
SCPI Commands and Queries - This subsection describes the SCPI command
organization and syntax
IEEE 488.2 Common Commands - This subsection lists the commands and
argument structures that are common to all SCPI commands
Constructed Mnemonics - This subsection describes the usage of constructed
mnemonics by the TG8000.
Block Arguments - This subsection describes the usage of block arguments
by the TG8000.
Special Characters - This subsection lists the special character sets that are
used by the remote control interface.
Programming model
Specific conditions must exist before programming commands will affect the test
signal generated by a module.
Selecting the module Select the module to be addressed before executing any commands. Many of
the commands used by the TG8000 are shared by several modules and will be
accepted without a reported error.
Command arguments Many commands accept either string or numeric arguments. For example: a
boolean argument can either be "1" or "ON".
Signal parameter commands that have a :STEP node can accept either a numeric
value or a string argument that refers to the :STEP increment.
Select signal parameter commands accept either a numeric value or one of the
following strings:
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.
Draft
TG8000 Multiformat Test Signal Generator Programmer Manual 5

TG8000 syntax
MINimum. Use this argument to query the minimum value or set the parameter
value to the minimum acceptable value.
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.
NOTE. If the TG8000 does not return a value in response to a MIN or MAX query,
then the values are undefined and an error message is generated.
Query arguments If you send a query with no argument, the response is the current value. You can
also use MINimum, MAXimum, and DEFault as arguments for queries whose
command form can use these arguments (refer to the command syntax for the
specific command). Instead of returning the current value, queries using these
arguments return the following information:
MINimum. Returns the minimum acceptable value.
MAXimum. Returns the maximum acceptable value.
DEFault. Returns the default value.
Argument example The following example demonstrates the effect of each of the arguments when
used with a step value:
1. :INSTrument:SELect "HDVG7:#" selects the HDTV digital video generator
module located in the slot number indicated by the "#" symbol.
2. :OUTPut:CIRCle:STATe ON displays a circle on the video display.
NOTE. :OUTPut:CIRCle:DIAMeter uses an argument that is the percent of
picture height.
3. :OUTPut:CIRCle:DIAMeter DEFault sets the circle diameter to 90 percent
of the screen height.
4. :OUTPut:CIRCle:DIAMeter:STEP 10 sets the step increment to 10 percent.
5. :OUTPut:CIRCle:DIAMeter DOWN changes the circle diameter to 80
percent of the screen height.
6. :OUTPut:CIRCle:DIAMeter 50 changes the circle diameter to 50 percent
of the screen height.
Draft
6 TG8000 Multiformat Test Signal Generator Programmer Manual

TG8000 syntax
7. :OUTPut:CIRCle:DIAMeter MAXimum changes the circle diameter to 100
percent of the screen height.
8. :OUTPut:CIRCle:DIAMeter MINimum changes the circle diameter to 0
percent of the screen height.
9. :OUTPut:CIRCle:DIAMeter UP changes the circle diameter to 10 percent
of the screen height.
10. :OUTPut:CIRCle:DIAMeter MAXimum queries the maximum circle
diameter (not the current diameter). The query returns the value of 100
percent, which is the maximum circle diameter allowable.
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 TG8000 uses a command
language based on the SCPI standard.
The SCPI language is based on a hierarchical or tree structure (see Figure 2-1) that
represents a subsystem. The top level of the tree is the root node; it is followed by
one or more lower-level nodes.
Figure 3: Example of SCPI subsystem hierarchy tree
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 2-1, 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.
Draft
TG8000 Multiformat Test Signal Generator Programmer Manual 7

TG8000 syntax
For example, OUTPut:CIRCle:STATe ON is a valid SCPI command created from
the hierarchy tree in Figure 2-1.
Creating queries 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 2-1.
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 TG8000 command set and
some are definedbyANSI/IEEE488.2-1987(seeTable2-1).
