Option R&S CMU-B17 provides
separate access to IF / IQ
signals on R&S CMU200
receiver (RX) and transmitter
(TX) paths (pls. see also annex
1). The functionality is applicable
for Signalling and Non Signalling
measurement modes. The
insertion of option R&S CMU-
B17 in bypass mode does not
cause any influence to signals;
i.e. the additional insertion loss of
R&S CMU-B17 will be
considered during mandatory
calibration procedure after
installation.
