Measurement Functions
Trigger Function
Step delay time for staircase sweep measurements.
When performing sweep measurements without a pulsed SMU, the 4155B/4156B
outputs an edge trigger at the time when the 4155B/4156B starts performing
measurement in each sweep step as shown in the following figure.
The step delay time you specify for trigger is the time from when the trigger is
output to when the next step occurs. This is to make sure the external instrument has
enough time to make the measurement. Available setting range for the step delay
time is:
Range: 0 to 1 s
Resolution: 100 ms
Trigger output delay time is shown as T2 in the following figure.
If the specified T2 is shorter than the measurement time of the 4155B/4156B, the
4155B/4156B waits until the measurement completes, then outputs the next step.
