1. Measure R, L, C of your cable using the 4284A. Measurement setup is as
follows:
GUARD (C) GROUND (E)
FORCE or SENSE (A)
Measurement
Parameter
R
L
C
a. See figure above.
b. Select 1 point in the frequency range.
c. For triaxial cable, connect B to F directly, and measure L
between A and E.
For coaxial cable, connect B to D directly, and measure L
between A and C. Ignore E and F.
2. Overwrite the R, L, C data in the program lines listed below. The data must be in
per meter values.
Program Line No.
