5.6.4.2 R&S RT-ZD differential probes
Figure 5-9: Probe setup for active differential probe R&S RT-ZD40
The offset is the differential offset. See "Offset" on page 139.
Specific settings for R&S RT-ZD probes are the following:
CM offset
Sets the common-mode offset to compensate for a common DC voltage applied to
both input sockets (referenced to the ground socket). Offset compensation is particu-
larly helpful for measurements on differential signals with high common mode levels,
for example, current measurements using a shunt resistor. You can measure the com-
mon mode input voltage using the R&S ProbeMeter.
The setting is available for Rohde & Schwarz differential probes, and for modular
probes in DM or CM mode (see "DM Offset, CM Offset, P Offset, N Offset"
on page 159).

Probe attenuator RT-ZA15
If you use the external attenuator R&S RT-ZA15 together with one of the differential
active probes R&S RT-ZD10/20/30, enable RT-ZA15 to include the external attenuation
in the measurements.
