If the R&S ZNB is equipped with variant 02 of the extension board, a slightly different
user interface is shown. The "Measurement" columns are hidden and the remaining

●
The upper part gives access to the RFFE interface settings and allows manual
command execution and result display (see

●
The lower part allows you to define and apply test voltages and to execute voltage
and current measurements on the RFFE pins (see
