MEASure subsystem
MEASure subsystem
The MEAS subsystem has a set of unique commands. These are the
measurement command <meas cmnd> set. They control features of the
Test Set such as setting measurement limits, units and the meters. See
“Number Measurement Syntax” on page 283 for more details about
these commands.
Most commands have both a <meas cmnd> parameter and a query
command.
• The command using <meas cmnd> allows you to set certain
parameters of the measurement such as limits, averages, and units.
• The query command is the command that reads the measurement
and returns a value.
:RESet
This command resets all measurements in progress.
