Configuring M9018B/M9019A PXIe Backplane Triggers
When using the Keysight M9018B/M9019A 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.
The Keysight M9018B/M9019A PXIe Chassis does not remember the trigger
bus configuration upon cycling power. After a power cycle, you must
reconfigure the bus triggers by using the M9018B/M9019A SFP or by creating a
persistent configuration by using the KtMPxiChassis API. Refer to the Keysight
M9391A PXIe VSA and M9381A PXIe VSG Programming Guide (M9300-90080)
for details and programming examples. This document is available on your

Procedure for Configuring PXIe Backplane Bus Triggers
Make sure you have followed Steps 1 through 4 in this Startup Guide to
setup and configure the Keysight M9381A PXIe Vector Signal Generator.
Conduct a Self Test (
). If your
Utilities > Self Test... > Run Self Test
configuration straddles two slot groups, you will receive error messages.
In the following graphic a Self Test has been run on an M9381A that is
installed in slots 5 through 9; therefore, it straddles two slot groups. The
Self Test detects errors with backplane triggers 6 and 7.
