Capacitance Compensation When Using Switching Matrix
To obtain compensation coefficients
Obtain the compensation coefficients as shown below.
1. Select the measurement frequency (Fmeas) used for the capacitance
measurement of a device under test (DUT), and set it to the MFCMU. The
coefficients must be measured at the same frequency.
2. Perform the MFCMU open calibration at the measurement terminal. Optionally,
perform short calibration if you want.
3. See Table 3-10 and Figure 3-23, and set the MFCMU.
4. Connect the path/cable corresponding to C3H (DATA07) shown in Figure 3-22
to the MFCMU. Then measure and record the R, L, and C values.
5. Connect the path/cable corresponding to C3L (DATA08) to the MFCMU. Then
measure and record the R, L, and C values.
6. If you use the connector plate, perform the following procedure.
a. Connect the path/cable corresponding to C2H (DATA05) to the MFCMU.
Then measure and record the R, L, and C values.
b. Connect the path/cable corresponding to C2L (DATA06) to the MFCMU.
Then measure and record the R, L, and C values.

For coaxial cable, ignore E and F, and connect B to D directly, and measure
L between A and C.
