Abstract
This report describes a portable S-band demodulator. The demodulator is a first-order phase-locked loop designed to work directly with the nominal levels out of the Deep Space Instrumentation Facility exciter and or transmitter. This demodulator provides an independent means for verification of the exciter/ transmitter performance. Its primary utilization is the measurement of exciter/ transmitter, amplitude stability, short-term phase stability, modulation index, bandpass, and modulation fidelity.
