Recommendations for Cross Channel Phase
When conducting a cross channel phase analysis, we recommend you:
1. Determine the exact frequency of interest. To do this, you can use
spectra to identify high amplitude peaks at specific frequencies.
2. Position the channel 1 sensor in a location which has high vibration
at this frequency. Do NOT move this sensor once testing has started.
3. Try out different locations with the channel 2 sensor, noting the
phase and amplitude relationships compared to the fixed channel 1
position.
4. Repeat steps 2 and 3 at any other locations of interest.
