Abstract
Test apparatus for a wireless system is provided in which an audible annunciation is produced which is an accurate indication of the measured received signal strength. A signal is derived from the receiver which is representative of the signal strength and which is employed to activate a speech synthesizer which provides annuciation of each of a range of digits, each digit annunication representing a predetermined increment of received signal strength.
