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.

To manually enter the RPM:
There are three options for entering the RPM:
dBase - Take the RPM value from the database if previously assigned to the POINT.
 This option only appears if the currently selected POINT in ROUTE
mode has a speed entered.
Type In - Type in the value using the numeric keypad, or
