Specify the hold time of the sweep start voltage. At the sweep start point, the
start voltage is forced for more than the specified time.
Setting range: 0 to 655.35 s
•
Delay Time
Specify the delay time of the measurement at each sweep step. The measurement
is executed after waiting for more than the specified time at each sweep step.
Setting range: 0 to 65.535 s
•
Zero Bias Time
Keeps 0 V at every terminal for more than the specified time after one sweep
measurement.
Setting range: 0 to 99.9 s
In the measurement of the same capacitance parameter as shown in the
following table, the characteristics results by the single measurement and the
continuous measurement may have the difference depending on the bias voltage
condition between the measurements. This parameter is used to cancel the
dependence on the bias voltage condition in the continuous measurement.
