5. TRACE NOISE TEST
Description
This test checks the trace noise level for each test port of E5071C. The trace noise level is
quantified by performing a “through” measurement 32 times from 9 kHz to 8.5 GHz range
(for up to 8.5 GHz options) or from 300 kHz to 20 GHz range (for over 8.5 GHz options),
with a cable connected between two ports. The trace noise level for S11, S22, S33 and S44
are quantified by performing a “short” measurement 32 times from 9 kHz to 20 GHz range,
with a cable (terminated with “Short” device) connected to each ports(1,2,3, and 4).
Standard deviation of the measured values at each frequency is calculated and, then
translated into a noise level expressed in dB rms / deg rms.
