Cvu Frequency Sweep (Bias) - Keithley 4200-SCS User Manual

Section 3: Common Device Characterization Tests
3. After the built-in system delay and programmed delay, the 4210-CVU makes a
measurement. The AC test signal is applied just before the start of the measurement. AC
drive is turned off after the measurement is completed.
4. Steps 2 and 3 are repeated for the -2 V, 3 V and -4 V DC bias voltages. The hold time delay
repeats at the beginning of each subsequent step.
The sweep delay, hold time and output disable are set from the
window for sweeping.
