Abstract
A receiver test apparatus that injects a plurality of attenuated test sigs into a receiver under test is improved by contemporaneously injecting a test message to identify the level of the attenuation test signals so that an operator may easily identify the level at which receiver anomalies occur. The test signals and messages are programmed so that testing may be easily reproduced.
