Set the overlap in Analyze


Overlap controls how much each new average overlaps the previous average when taking a spectra measurement. The higher the overlap percentage, the less newly acquired data is needed to generate a spectrum. A higher percentage decreases the data collection time.

The default overlap, 67 percent, is acceptable for most situations.


  1. From the Analyze main menu, press ALT > F4 Set Overlap.
  2. Enter a percent between 0 and 99.
    The default is 67 percent.
  3. Press Enter.
