The ILS Monitor Precision Calibrator is VHF-UHF signal generator, with internal modulation capability to generate Localizer (VHF) and Glide Slope (UHF) signals. The purpose of the work was to develop a single equipment to provide suitably accurate ILS RF and demodulated RF for Categories II/III ILS ground equipment monitors. It is used to verify correct response and proper alarm limit settings for ILS monitor and ILS receivers. In addition, the equipment contains a digital frequency readout indicating the output RF frequency and a digital readout that indicates DDM on dual tone and percent modulation on single tone.
