Collect Advanced Cross Channel data

 

Overview

The Advanced Cross Channel measurement is similar to a spectral measurement. Advanced Cross Channel uses two or more channels to determine the phase difference between the channels. You can see how one signal reacts to a known force applied through the other channel, similar to an impact test. Use Advanced Cross Channel to determine resonance, misalignment, phase imbalance, or looseness.

Procedure

  1. Create a job.
  2. From the Analyze main menu, press F1 Manual Analyze > F1 Set Analyze Mode.
  3. Use the up and down arrow keys to select Advanced Cross Channel.
  4. Press Enter.
    The Analyze Setup screen appears.
  5. Set the following options as necessary.
    Option Description
    F2 Set Spectra Params Set the Fmax, Fmin, and lines of resolution. See Fmax and Fmin and Lines of resolution.
    F3 Set Averaging Set the type of average to calculate. Enter a value between 0 and 10,000 to set the number of averages. See Averaging. The default is 1.
    F4 Set Window Set the type of window to use. See Windows.
    F6 Plot Setup Set the types of plots to display during and after data collection.
    F7 Tach Setup Set up the tachometer parameters. See Set up a tachometer in Analyze.
    F8 PeakVue Demod Enable or disable PeakVue or Demodulation. See PeakVue and demodulation.
    F9 Set Trigger Select the type of trigger to use to start the measurement. See Triggers.
    F11 Ref Input Select the input to use as your reference. If you disable the reference input from the Input Setup screen, "???" appears until you press F11 Ref Input.
    F12 Input Setup Set up the input channels, the sensor type, and the units for the acquisition type.
  6. Press Enter to collect the data.
    One or more plots display the data.
  7. Press F2 Next Response Input to display data for the next response, if you set up more than two inputs.
  8. Press F9 Store Data to save the data to a route or a job, or press F8 Start to redo the measurement.
