Apparatus and method for verifying performance of digital processing board of an RF receiver
摘要
A testing apparatus for the digital processing portion of a satellite receiver. A software program generates an (I) and (Q) file of root cosine filtered (I) and (Q) DQPSK modulated sampled waveform. The waveform is coupled to a test board that stores the files in a PROM and generates the waveform at a rate determined by the receiver being tested. The output of the test board replaced the A/D converter of the receiver for testing. The waveform impairments are added to the stored software waveform.
