User Manual PXA125
Specifications A-98
Description Provides dual functionality. All functions and modes, this output generates
sync pulse, which is synchronous with the output waveform. In FM and sweep modes only, this out-
put generates a marker having properties similar to the sync pulse output. The SYNC pulse can be
routed to the PXI backplane to one or more of the TTL Trigger lines, thus providing trigger outputs to
other modules. Front and backplane outputs are available simultaneously.
Outputs
Front panel SYNC Output BNC connector
PXI Backplane TTLTrig 0 through 7, programmable
STAR 0 through 7, drive slots 3 through 10 when module is plugged
into slot 2 only. No individual control for each star line, all are either on, or off.
Validation
BIT Generates a sync signal each time a point within a specific wave
segment is accessed.
LCOM (Loop Complete) Generates a single SYNC signal. Starts at a begin-
ning of a sequence and ends at the end of the sequence.

Sine Output
Description An output that is directly derived from the sample clock generator and has an
output frequency equal to the programmed sample clock frequency. This output generates sine
waveform that corresponds to sample clock setting, including modulated waveform, such as FM,
sweep and FSK
