ABSTRACT:
A test and measurement system for space satellite antennas which includes frequency synthesizers which are capable of shifting from frequency to frequency at high speeds with precision accuracy to provide source and reference frequencies with which the antennas may be tested; a transmitter utilizing one of the frequency synthesizers to generate test signals; an optional power monitor receiving antenna; a non coherent receiver utilizing the other of the frequency synthesizers to generate local reference frequency signals; high speed electronic switching networks connecting the various antennas to be tested with the receiver at the receiving antenna; a network for converting received signals to digital signals and storing those signals; and a computer system for controlling the transmitter, the receiver, and the switching systems, and the data converting and storage network.
