4-20 Phase Mod - Min Phase Deviation Tests
The Phase Mod - min phase deviation tests are as follows:
Ext Low Noise ΦM Min Deviation
This test verifies that, at 5 GHz carrier frequency, Ext Low Noise Phase Mod with sensitivity set to minimum,
will produce 1 mrad (nominal) deviation for a full-scale (1vpk sine) Ext mod input. At other carrier frequencies
min phase deviation setting scales by factors of 10 in rough proportion to Nmod. (See
).
Test Setup
.
FSWP
Tab “Spectrum”. This will close the previous measurement window and activate the RF Spectrum display.
Span = 5 kHz, RBW = 100 Hz, VBW = 10 Hz, Trigger = Continuous.
External Function Generator: 1 kHz, 2.0Vpp, Channel ON.
MG362x1A:
Phase mod OFF, Ext Low Noise Phase mod mode, DC Coupled, Ext Phase Mod Sensitivity =
1 mrad/V. Set Ext Low Noise Phase Mod ON.
Test Procedure
1.
Set SPA marker 1 = normal. Set marker 1 freq = 5 GHz.
