Capacitance Compensation

Capacitance Compensation

When the capacitance/conductance measurement is performed through the Agilent B2200, LCR meter measures the capacitance/conductance of the path including a device under test (DUT), matrix switches, extension cables and so on. So, the data measured by the LCR meter is far from the DUT’s capacitance/conductance.

The Agilent B2200 VXIplug&play driver provides the functions used to compensate the capacitance/conductance measured by the Agilent 4284A LCR meter in the measurement environments described in “Required Conditions” on page 4-21.

This section explains how to use the capacitance compensation function.

Capacitance Compensation Function

Driver functions used for the capacitance compensation are listed below.

•agb220xa_selectCompenFile function

•agb220xa_compenC function

Corrected data by the function is not guaranteed. But typical data (supplemental data) is as follows.

Capacitance measurement accuracy (typical): ±1 % ±0.5 pF

This typical data is for the following measurement conditions:

Measurement frequency: 1 kHz to 1 MHz

Measurement range: Maximum 1000 pF

Measurement terminal: At the end of the Agilent 16494A/B/C cable connected to the switch module output terminals.

The typical data does not apply to anything extended from the 16494A/B/C cable. The conditions described in “Required Conditions” on page 4-21 must be satisfied.
