Quasi-static C-V Measurements
Defining Measurement Conditions
Defining Measurement Conditions
This section describes the QSCV measurement tasks.
The overall procedure for testing your DUT is as follows:
1 Connecting your DUT to the 4155C/
4156C.
See Chapter 10 for procedures.
2 Defining measurement mode and
measurement units that you use to do
measurement.
See “To Define Measurement Units” on
pages 4-10. Also, see Chapter 8 for the
user function and standby function.
Ignore the SERIES RESISTANCE and
DISCHARGE fields; they are not
available for the QSCV measurements.
3 Setting the source conditions. See the
following in this section:
• “To Set up QSCV Sweep Source”
• “To Set up Stop Condition”
• “To Set up Constant Output”
• “To Set up PGU Output”
For setting the measurement conditions,
see following in this section:
• “To Define Measurement Conditions”
