2. Measure the R, L, C values of the C2x or C3x path by using the Agilent 4284A.
3. Open the template file selected at step 1 by using a text editor. Exchange the R,

coefficients
C2H For the Agilent B2220A probe card interface, do not modify
the lines.
C2L
For 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 C2x
path (triaxial cable with connector plate) shown in Figure 4-6.
C3H Change the R, L, C values in the lines. The value must be
changed to the R, L, C values of the C3x path.
C3L
For the Agilent B2220A probe card interface, probe card will
be used for the C3x path.
For the connector plate, coaxial cable with positioner will be
used for the C3x path.
See "To obtain compensation coefficients" on page 4-26.
After the measurements, calculate the per meter value of the R, L, C, and record
them into the following table.

your compensation data file (e.g. C:\temp\my_env_1.txt).
Do not change any other lines. Also do not change the value for the coefficients
that should not be modified.
