Abstract :
A centralized method of testing Mobile, Test and Base Station Transmitters “Off the Air” has always been considered desirable. With the inauguration of 450 Mc. narrow band common carrier telephone service with its more stringent requirements, a centralized method of testing has become almost a necessity. The Centralized Mobile Telephone Test Panel described herein can be used to evaluate the overall performance of a Mobile telephone system and can also be used as a tool to insure proper routine operation of a system. Provisions are made in the CMTTP for automatic sampling of each radio channel with statistical evaluation of ON-OFF frequency operation of mobile transmitters. The present unit is arranged to monitor on the 450 Mc. and Personal Signaling (Bellboy) services only. However, the test panel can be readily adapted for the 40 and 150 Mc. channels as well.
