3.5.6.10 Cable Length Correction
The cable length correction corrects an additional error due to the connection cable between
ZM2371 / ZM2372
and DUT.
The
ZM2371 / ZM2372
use coaxial cables of impedance 50  (cable capacitance = about
100pF/m) and the length of four cables must be same. Using the cables having different
characteristics may increase a correction error. Particularly for the L
CUR
and L
POT
cables, the
cables having same specified characteristics and length should be used.
The cable length correction is operated with the cable length correction menu.
