Capacitance Compensation When Using Switching Matrix
• For E5250A:
The lines DATA05 to DATA08 should be modified fo
r each measurement
environment. See Table 3-9. Do not modify the other lines.

Modifications of data file
C2H
(DATA05)
C2L
(D
ATA06)
Fo
r the connector plate, change the R, L, C values in the lines.
The value must
be changed to the R, L, C values of the
C2H (DATA05) path and the C2L (DATA06) path (triaxial
cable with connector plate) s
hown in Figure 3-18.
For Agilent B2220A probe card interface, do not modify the
lines.
C3H
(DA
TA07)
C3L
(D
ATA08)
Ch
ange the R, L, C values in the lines. The value must be
changed to the R
, L, C values of the C3H (DATA07) path and
the C3L (DAT
A08) path shown in Figure 3-18.
For the connector plate, the coaxial cable with positioner will
be the appropriate path.
F
or Agilent B2220A probe card interface, the probe card will
be the appropriate path.
