Option CMU-B17 provides separate access to the I/Q and IF signals in the CMU200 receiver (RX) and transmitter (TX) paths. The functionality is applicable in conjunction with the RF function group (see section I/Q-IF Interface (Connection Control – I/Q-IF)) and with a wide range of network options in Signalling as well as in Non Signalling test modes (see separate manuals for network options). The insertion of option CMU-B17 in bypass mode does not cause any influence on signals; i.e. the additional insertion loss caused by option CMU-B17 will be corrected during the mandatory calibration procedure after installation.
