Selecting the Cable Length

Functional Description
The E4980A/AL has four reference planes (points): the UNKNOWN terminal (0
m), the tip of the 16048A/B test lead (1 m), the tip of the 16048D test lead (2
m), and the tip of the 16048E test lead (4 m). These points serve as the basis
for the measurement accuracy.
When you select a cable length of 0 m, you have to use the UNKNOWN
terminal to interconnect the outer contacts of lead wires Hcur, Hpot, Lpot, and
Lcur.
When you select a cable length of 1 m, you have to use the tip of the 16048A/B
1m test lead to interconnect the outer contacts of lead wires Hcur, Hpot, Lpot,
and Lcur.
When you select a cable length of 2 m, you have to use the tip of the 16048D
2m test lead to interconnect the outer contacts of lead wires Hcur, Hpot, Lpot,
and Lcur.
When you select a cable length of 4 m, you have to use the tip of the 16048E
4m test lead to interconnect the outer contacts of lead wires Hcur, Hpot, Lpot,
and Lcur.
The four-terminal pair structure is terminated at the tip of your selected cable
length. When you use the 16048A/B/D/E test lead, connect the supplied
terminal plate to the tip of the cable to terminate the four-terminal pair
structure.
