The lines DATA05 to DATA08 should be modified for each measurement
environment. See Table
coefficients
C2H For the connector plate, change the R, L, C values in the lines.
(DATA05) The value must be changed to the R, L, C values of the
C2H (DATA05) path and the C2L (DATA06) path (triaxial
C2L
cable with connector plate) shown in
(DATA06)
For Keysight B2220A probe card interface, do not modify the
lines.
C3H Change the R, L, C values in the lines. The value must be
(DATA07) changed to the R, L, C values of the C3H (DATA07) path and
the C3L (DATA08) path shown in
C3L
(DATA08) For the connector plate, the coaxial cable with positioner will
be the appropriate path.
For Keysight B2220A probe card interface, the probe card will
be the appropriate path.
