Configuring M9018A PXIe Backplane Triggers
When using the Keysight M9018A PXIe 18-slot Chassis, you should install the
M9381A modules entirely within one of the slot groups: 1 through 6, 7 through 12,
or 13 through 18. If you install the M9381A modules straddling any of these groups
of slots, you will have to reconfigure the chassis's PXIe trigger bus routing for
trigger 6 and trigger 7.
In both 2x2 configurations described in the
2x2 M9391A and M9381A Instrument
section, backplane triggers will have to be applied to the VSA #2 and
the VSG #1. This is because VSA #2 straddles slot groups 1 and 2. VSG #1
straddles slot groups 2 and 3.
Backplane Triggers Used
PXIe backplane trigger 6 is used to route the External Trigger signal from the
Keysight M9301A PXIe Synthesizer front panel to the Keysight M9311A PXIe
Digital Vector Modulator. Trigger 6 can be reassigned using API hints. You
can use backplane triggering directly to the M9311A (no M9301A involved)
by selecting the External Trigger source to be PXIe trigger 0 to 7.
PXIe backplane trigger 7 is used for routing the ALC Trigger signal from the
Keysight M9311A PXIe Digital Vector Modulator to the Keysight M9310A
PXIe Source Output. Although the default is PXIe trigger 7, it can be
reassigned using API hints.
