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 ITM timing
window for sweeping.

Figure 3-21 shows an example of a FFMO window with CVU Frequency Sweep
(bias) selected as the forcing function to measure Cp-Gp. The Sweeping test
mode must be selected for this test (see Figure 3-11).
