# END of Data
The lines DATA05 to DATA08 should be modified for each measurement
environment. See Table 3-9. Do not modify the other lines.
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 Figure 3-18.
(DATA06)
For Agilent 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 Figure 3-18.
C3L
(DATA08) For the connector plate, the coaxial cable with positioner will
be the appropriate path.
For Agilent B2220A probe card interface, the probe card will
be the appropriate path.
