Common Mode Offset

Common mode offset compensation is available for R&S RT‑ZD probes with
serial number ≥ 200 000. It can compensate a common DC voltage applied to
both input sockets (referenced to the ground socket). This is particularly helpful
for measurements on differential signals with high common mode levels, for
example, current measurements using a shunt resistor.

If the input signals fit into the operating voltage window of the R&S RT-ZD40, it is
not necessary to set a common mode offset compensation.
