Operation model for triggering example
A) Turning the SourceMeter OUTPUT ON places it at point A in the flowchart, where it
waits for an external trigger.
B) Pressing STEP takes the Model 7001/2 out of the idle state and places operation at
point B in the flowchart.
C) For the first pass through the model, the scanner does not wait at point B. Instead, it
closes the first channel (point C).
D) After the relay settles, the Model 7001/2 outputs a trigger pulse. Since the instrument is
programmed to scan 10 channels, operation loops back to point B, where it waits for an
input trigger.
E) and F) With the SourceMeter operation at point A, the output trigger pulse from the
Model 7001/2 triggers a measurement of DUT #1 (point E). After the measurement is
complete, the SourceMeter outputs a trigger pulse and then loops back to point A, where it
waits for another input trigger.
