Form Set & Query
Description This command programs the trigger output source mode.
•PERiodic
This corresponds to Pulse mode on the front panel.
The trigger source is the internal clock, and a trigger pulse is
generated every clock period, unless the divider parameter has
been set to a value other than 1. The trigger signal always has
50% nominal duty cycle.
•BITStream
This corresponds to the Data mode on the front panel.
If the clock source is external, the trigger is always synchronized
to the clock with a fixed delay (± a few picoseconds over the
frequency range). PERiodic means that a trigger pulse is
generated for every X clocks, BITStream means that X is set to
the data length.
The trigger divider does not take the frequency divider of the
channels into account. For a frequency divider of n, n trigger
pulses are generated for each data packet, starting with the first
edge of bit 0 of the data packet.
To get one trigger pulse per data packet when the channel
divider factor is not equal to 1, the trigger mode must set to
Trigger on pulse and the divider to n x X, where n is the
frequency divider and X is the data length. For example, if the
data length = 32 bits and the frequency divider of channel 1 = 2,
the frequency divider of the trigger output has to be 64.
