Triggering Commands - Keithley 2750 User Manual

8-16 Triggering
The trigger model can be configured to output a trigger after the completion of a series of
measurements, or after every measurement. For example, with the sample counter set to
10 and the trigger counter set to one, a trigger will be sent after the 10 measurements are
performed. If instead, the trigger counter is set to 10 and the sample counter is set to 1, a
trigger will be sent after each measurement.
