A Two Channel SCross-Channel Phase Display Screen.
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 phas
e
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 on the spectrum or as a table of magnitude/phase pairs of up to 8
orders of running speed. In a two channel

of input CH1 relative to input CH2
