Triggering
With a Keithley pulse card selected as the trigger master, its Trigger Out can be used to start (trigger)
itself or other pulse cards in the system.
For the master pulse card, the polarity of the pulse trigger source (pulse_trig_source) and pulse
trigger polarity (pulse_trig_polarity) function must be the same. If you are using a rising-edge
trigger source, the pulse trigger polarity must be positive. If you are using a falling-edge trigger
source, the pulse trigger polarity must be negative. This requirement applies to all pulse modes,
including Standard Pulse, Segment Arb, and Full Arb.
When triggering multiple pulse cards in a master/subordinate configuration, changing the trigger
output polarity of the master card results in a transition in the trigger output levels that may be
interpreted as a trigger pulse by the other cards.
