Most of the up-to-date CMC test sets (e.g., CMC 256 , CMC 256plus , CMC 353 ,
CMC 356 or CMC 850 ) provide power supply to the CMGPS via the connection
cable to the ext. Interf. . Therefore, in conjunction with one of these test sets, the
power supply unit is not needed.
In conjunction with the CMIRIG-B interface unit, use the above mentioned power
supply unit to power the CMGPS .
Note that using such a separate power supply unit keeps the CMGPS in "locked"
mode when the CMC test set is switched off.
