Spectrum Analysis with the AN/USM-410(V)

The automated spectrum analysis provided by the AN/USM-410 test equipment is accomplished with a programmably tuned receiver with VDT and hardcopy numerical output data instead of the usual visual scope presentation. The present implementation is for 20 MHz to 18 GHz. Software calibration connection routines have been developed to enhance measurement time accuracy. The local oscillator signal synthesis is controlled by the run time system to insure avoidance of otherwise residual spurious responses. A wide range of input power levels and IF signal conditioning are user programmable.
