Quasi-static C-V Measurements
Defining Measurement Conditions
To Set up Constant Output
Constant source is the source unit defined as CONST in the CHANNELS:
CHANNEL DEFINITION screen. To set up the constant output source, press the
Meas front-panel key. The MEASURE: QSCV SETUP screen is displayed.
1. CONSTANT: SOURCE
Enter the desired output value of the constant source.
2. CONSTANT: COMPLIANCE
Only for SMU. Enter the compliance value for the constant source.
You cannot change UNIT, NAME, and MODE in this screen. To change the values,
go to the CHANNELS: CHANNEL DEFINITION screen.
To Set up PGU Output
In the QSCV measurements, you can use the PGU as the DC voltage source, not the
pulsed voltage source. To set up the constant voltage source, press the
Meas
front-panel key, and select the PGU SETUP softkey. The MEASURE: PGU SETUP
screen appears. The PGU SETUP softkey is available when you set PGU in the
CHANNELS: CHANNEL DEFINITION screen.
1. IMPEDANCE
Select a secondary softkey to set the output impedance value:
• LOW for approximately zero ohm output impedance
• 50 ohm for 50 ohm output impedance
2. CONSTANT: SOURCE
Enter the desired output value of the constant voltage source.
You cannot change UNIT and NAME in this screen. To change the values, go to the
CHANNELS: CHANNEL DEFINITION screen.
