Model 2601B-PULSE System SourceMeter Instrument Reference Manual Section 4: Sourcing and measuring
2601B-PULSE-901-01A April 2020 4-43
The following figure shows the general sequence for SMU measurement triggering. The basic
sequence is as follows:
• When the output is turned on, the programmed source value is immediately applied to the device
under test (DUT).
• Through front panel only: If the immediate trigger source is selected, a measurement is triggered
immediately. However, if the manual trigger source is selected, the front-panel TRIG key must be
pressed.
• The instrument waits for the programmed delay period (if any).
• The instrument takes one measurement.
• If the number of measurements is less than the programmed trigger count, it cycles back to take
another measurement (the measurement cycle will be repeated indefinitely if the infinite trigger
count is selected).
• For multiple measurements, the instrument waits for the programmed trigger interval (if any)
before taking the next measurement.
