10. Press Number of Averages > Select the required number of
averages.
NOTE: Coherence calculations require spectral averaging to be
performed. This means if you set the number of averages to 1,
Coherence will not display.
Measure Cross Channel Phase
To measure cross channel phase:
1. Press or Measure.
2. Use the navigation keys provided to locate and select Cross
Channel Phase > Press .
3. Select the required parameter set you have set up > Press —
Recording will start automatically.
4. Press to display labels for the additional viewing options:
5. Press to zoom in to the Y axis.
6. Press to expand the Y axis.
7. Press to zoom in to the X axis.
8. Press to expand the X axis.
9. Press to move the cursor left.
10. Press to move the cursor right.
11. Press to change the display of the sensor orientation.
NOTE: The instrument will perform a spectral peak search on the
reference channel at the frequency entered. The frequency of the
actual peak displays in the top right of the screen. The instrument
then looks at exactly the same frequency on the other response
channels and displays the phase difference Delta <value> Ø2/Ø1
(CH2 - CH1). The instrument also displays the phase angles and
amplitudes of both channels at your chosen peak frequency.
