Capacitance Compensation

To Perform Measurement and Compensation

Perform the capacitance measurement and compensation as shown below.

1. Set the Agilent 4284A measurement condition. Then the frequency must be the

value (Fmeas) used when the compensation coefficients are measured.

2. Before contacting the device under test (DUT), perform the Cp-G measurement

in the open condition at the end of the measurement path including positioner or

probe card, and record the measurement data (C1 and G1). See Table 4-12.

3. Perform the compensation by using the capacitance compensation function, and

record the result data (C1r and G1r).

See Table 4-13 for the example to use the capacitance compensation function.

This example uses Microsoft Visual C++.

4. Contact the DUT, perform the Cp-G measurement, and record the measurement

data (C2 and G2).

5. Perform the compensation and record the result data (C2r and G2r).

6. Perform the following calculation and record it as the capacitance value.

C = C2r - C1r
