4.4 COMMANDS
4.4.1 PROGRAMMING MESSAGES
Some commands accept an optional suffix. This suffix can be used to specify the explicit Q-RPT
to address. In most cases, each Q-RPT in the RPM4 operates as an independent measurement
device. If the suffix is not specified, then the “Active” Q-RPT is assumed.
The “RANGE” or “ARANGE” command can be used to select the “Active” Q-RPT. See the
program message descriptions for suffix use with a specific command.

‘n’ indicates an
optional suffix
