A Multi-Channel Stability Analyzer for Frequency Standards in the Deep Space Network

C.A. Greenhall, A. Kirk, R.L. Tjoelker

Abstract:	We present a final report on the development of a multi-channel Frequency Standards Stability Analyzer (FSSA) for characterizing and monitoring several frequency sources at each of the three Deep Space Network (DSN) sites and at JPL’s Frequency Standards Test Laboratory (FSTL). The system can simultaneously measure the relative stability of six independent 100 MHz frequency sources and one source at an arbitrary frequency (typically X or Ka band) when down-converted with a low-noise synthesizer. The measured noise floor is approximately 2x10-15 at 1 second and 1x10-18 at 4000 seconds, currently sufficient to measure all operational DSN frequency standards and distribution links. Four instruments are operating well in the DSN and the FSTL.
