Trig Out
Trig Out
This is an output trigger and is produced after each new hardware
frequency or power level setting has settled; the value of the dwell time
controls how long the trigger outputs (Sync Out trigger and Trig Out
trigger) are asserted. The Trig Out trigger can be directed to the Trig
Out connector on the hardware front panel or one of the eight-shared
VXI backplane TTL triggers (TTLTRG0-TTLTRG7) or both at the same
time. This output trigger can also be enabled when changing frequency
or power or both in set-spot mode.

Trig Out The trigger is present at Trig Out on the
hardware front panel of the synthesizer.
FRONT_OUT_POS = 16 Positive The Trig Out trigger is generated with a
positive polarity.
FRONT_OUT_NEG = 48 Negative The Trig Out trigger is generated with a
negative polarity.
FRONT_OUT_OFF = 0 Off No Trig Out trigger is output.

VXI Backplane TTL
Trigger
The Trig Out trigger is output to one of
the eight-shared VXI backplane TTL
triggers (TTLTRG0 - TTLTRG7). The
VXI backplane TTL triggers follow the
Synchronous Trigger Protocol as
outlined in the VXIbus Specification.
This means that the VXI backplane
trigger line is asserted low.
VXI_OUT_OFF = 15 Off No Trig Out trigger is output.
