SCPI Command Reference
Subsystems
The SCPI commands are divided into
subsystems
, which reflect the various
functionality of the instrument. The following figure shows where the
port-related subsystems are located.

Subsystems
Subsystem
Description
STATus
The STATus subsystem reports the current system condition,
when an event changes and sets transition filter states to
report when a passing event occurs.
TRIGger
The TRIGger subsystem selects the following trigger modes:
•
INTernal selects the 100 MHz reference clock of the AXIe
chassis.
•
REFerence selects a 10 MHz/100 MHz external reference
clock.
•
DIRect selects the clock in the M8041A and can be set
manually from 8.1 GHz to 16.2 GHz as the system
frequency.
•
CMULtiplier selects a multiplied or divided clock to
specify the system frequency.
SOURce
The SOURce subsystem controls output signals (for
example, for setting frequency and levels).
OUTPut
The OUTPut subsystem controls the output ports of the
pattern generator.
INPut
The INPut subsystem controls the input ports of the error
detector.
CLOCk
The CLOCk subsystem is used to detect clock source or to
set the clock frequency applied to input or output channel.
FETCh
The FETCh subsystem is used to query the error detector’s
results.
MMEMory
The MMEMory subsystem is used to store and recall
predefined or custom created settings and patterns.
