Syntax
This section contains information on the Standard Commands for Programmable
Instruments (SCPI) and the programming structure you can use to program your
module.
Programming Model
Specific conditions must exist before programming commands will affect the test
signal generated by a module.
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 are shared by several modules and will be accepted without a
reported error.
2. Enable the module using the :OUTPut:STATe ON command. You must
enable the output state of the module before you change the test signal
parameters.
Many commands will 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 they can accept a string argument that refers to the :STEP increment.
Signal parameter commands with a :STEP node will accept the following strings
in addition to a numeric 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.
