Abstract
A test device (101) for use in a trunked radio system (102) employs a received signal strength indicator (RSSI) detector (120) to analyze transmission parameters. The test device (101 ) includes a transceiver (118) for transmitting and receiving radio signals, and a channel controller (116). The test device further includes memory (117) for storing (403) data, and test control means (116) for causing the transceiver to receive (303, 406) outbound signals on active communication channels. The test device (101) then processes (303-305, 402-404) the power levels for the outbound signals, and either re-transmits (305, 307) the results, or stores (407) them in memory.
