IF Phase Ripple Performance Test

(Normal Variant Only)

This test is to be performed on PSA analyzers with Option B7J.

This test is a functional test. The IF Phase Ripple is measured in order to meet the EVM specification listed for various Digital Comms personalities. In this test the source is set to output 64 tones in groups of 8 tones which are generated synchronously. The tones are measured in groups to reduce error due to noise. An algorithm is applied to the measurement data to determine the relative phase between the tones.
