Abstract
A multi-channel Frequency Standards Stability Analyzer (FSSA) has been developed and installed in each of the three Deep Space Network (DSN) sites and at JPL’s Frequency Standards Test Laboratory. The FSSA can simultaneously measure and monitor the relative stability of six independent 100-MHz frequency sources and one source at an arbitrary frequency when downconverted with a low-noise synthesizer. Pairwise comparisons of any two sources connected to the system can be made at any time with no hardware reconfiguration. The measured Allan-deviation noise floor is approximately 2×10−15 at 1 second and 1×10−18 at 4000 seconds, currently sufficient to measure all operational DSN frequency standards and distribution links.
