Defining Measurement Conditions
8. DELAY TIME
Enter the delay time. 0 to 65.535 seconds, 100 μs resolution.
You cannot change UNIT and NAME in this screen. To change the values, go to the
CHANNELS: CHANNEL DEFINITION screen.
NOTE In the QSCV measurement, the 4155C/4156C executes the capacitance
measurement at the sweep steps except for the sweep start voltage and stop voltage.
At each sweep step, the capacitance measurement is executed over the voltage
range: output voltage ± capacitance measurement voltage/2.
To Set up Stop Condition
1. Press the Meas key in the PAGE CONTROL key group.
2. Move the field pointer to the QSCV Status field.
3. Select one of the following softkeys:
CONT AT ANY Sweep will continue even if an abnormal status occurs.
STOP AT ANY
ABNORM Sweep will stop if any abnormal status occurs.
STOP AT
COMPLIANCE Sweep will stop if the abnormal status 1 or 2 listed below
occurs.
Abnormal status means the following:
1. Integration time too short for the capacitance measurement
2. Compliance on the leakage current measurement unit
3. Compliance on the non-measurement unit
4. Overflow on ADC
5. Oscillation on any unit
