Changing OPM/PPM Settings
The pass/fail thresholds that you set for PON Power Meter (PPM) or Optical
Power Meter (OPM) projects and the predefined thresholds are applied on
the corresponding table tabs in the Results window. If you need to change
the threshold for analysis purposes, it can be done in the Thresholds tab.
To select which thresholds to use for the measurements:
1. From the main window, select the Settings menu, then OPM/PPM.
2. In the Pass/Fail Thresholds tab, select whether the thresholds to use
are those from the measurement file, or those from the application.
Note: In the case of FTTx measurements, you can only use the thresholds from
the measurement files.
3. Click OK to confirm your choice and close the window.
