Phase Noise Performance Test

This test verifies the analyzer noise sideband specification. The source can be either a Wenzel Ultra Low Noise source or a PSG. The Wenzel is the preferred solution.

The test requires that DANL at 1 GHz be characterized for the near noise corrections. If the DANL test has been run, the DANL test data will be used. If DANL has not been run, then the DANL will be characterized at 1 GHz.
