PXI-9527
Trigger Export
The PCI/PXI-9527 can export trigger signals to the SMB TRG
IO on the front panel, and PXI Trigger Bus Numbers 0 through
7. The TRG IO on the front panel can also be programmed to
output the trigger signal when the trigger source is generated
by software, PXI STAR, or PXI Trigger Bus Numbers 0 through
7. The PXI-9527 utilizes PXI Trigger Bus Numbers 0 through 7
to act as the System Synchronization Interface. When config-
ured as the output, the PXI-9527 serves as a master module
and can output trigger signals to synchronize the slave mod-
ules. The trigger signal can be routed to any of the seven PXI
Trigger Bus Numbers via software.
3.4.2 Trigger Mode
Two trigger modes applied to trigger sources initiate different data
acquisition timings when a trigger event occurs. The following trig-
ger mode descriptions are applied to analog input and analog out-
put functions.
Post Trigger Mode
If post trigger mode is configured, activity commences once the
following trigger conditions are met:
Z The analog input channel acquires a programmed num-
ber of samples at a specified sampling rate
Z
The analog output channel outputs pre-defined voltage
at a specified output rate
