How to Set Up a Cross Channel Phase Measurements
Overview
A cross-channel phase measurement displays the spectra for input channels 1 & 2, and
the relative phase angle between the two input channels. Note that the phase
difference between the two inputs is measured. This is known as
relative phase
.
Spectra for both input channels are stored, and the relative phase between the two
channels is displayed as a table of magnitude/phase pairs of up to 8 orders of running
speed.
