3 Programming the Analyzer
STATus Subsystem
X-Series Status Register System (2)

Detailed Description

The STATus subsystem remote commands set and query the status hardware registers. This system of
registers monitors various events and conditions in the instrument. Software written to control the
instrument may need to monitor some of these events and conditions.
All status register commands are sequential. Most commands can be started immediately and will overlap
with any existing commands that are already running. This is not true of status commands. All the
commands in the spectrum analyzer are assumed to be overlapped unless a command description
specifically says that it is sequential.
