Capacitance Compensation When Using Switching Matrix
In Figure 3-18, C1 (DATA04), C2H (DATA05), C2L (DATA06), C3H (DATA07),
C3L (DATA08) are the compensation coefficients defined in the compensation data
file. where, CxH is for the path connected to the MFCMU Hc-Hp terminal, and CxL
is for the path connected to the MFCMU Lc-Lp terminal.
When Agilent B2220A probe card interface is used, obtain the coefficients for C3x,
and create your compensation data file. In this case, probe card will be used for the
C3x path.
When the connector plate is used, obtain the coefficients for C2x and C3x, and
create your compensation data file. In this case, triaxial cable with connector plate
will be used for the C2x path. And coaxial cable with positioner will be used for the
C3x path.
For obtaining the compensation coefficients and creating the compensation data file,
see "To Create Compensation Data File" on page 3-50.
