Measuring Cross Channel Phase
The Cross Channel Phase measurement option has been enhanced. It's
easier to change the speed of interest during the recording. This could
be the actual speed of the machine or the frequency of interest.
Additionally you can choose the required filter bandwidth you wish to
monitor, and the number of averages you wish to take. While recording,
a graph displays on your screen, showing your data. You can adjust the
position of the cursor on this graph to access more details about a peak
of interest, including phase and coherence data.
