9.
Enter :OUTPut:SERial:AMPLitude UP
to change the amplitude of the
output signal to 20 percent.
10.
Enter :OUTPut:SERial:AMPLitude? MAXimum
to querie the maximum
amplitude of the output signal (not the current amplitude). The query returns
the value of 130 percent, which is the maximum amplitude 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 program-
ming 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 HDST1 module
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.

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.
For more information on SCPI commands, programming structure, and TG2000
Signal Generation Platform status and events, refer to the TG2000 Signal
Generation Platform User Manual.
