Triggering
Triggering is used for the following operations:
• Basic triggering (on page 4-23): Configure the Keithley pulse card for the trigger mode
(Continuous, Burst or Trig Burst) and use a software trigger to start pulse output.
• Pulse-measure synchronization (on page 4-24): Synchronize the pulse-measure operation of a
pulse generator card.
For each pulse in a test, a trigger pulse is sent to the trigger output. If you are using Segment Arb
waveforms, you can define if a trigger out is sent for each segment.
The 4220-PMU and 4225-PGU are trigger out only (no trigger in). These pulse cards use the internal
trigger bus for output synchronization when using any commands that require the pulse_exec
function to execute.
