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.

Standard pulse waveforms

Standard pulse waveforms are configured and controlled from the pulse card tabs in the KPulse
window. The following figure explains how to use KPulse for a standard pulse output.
Standard pulse waveform previewers: KPulse provides a preview of configured standard pulse
waveforms for each enabled channel. Each waveform previewer shows the high and low levels, and
timing for the waveform.
