Performing a Power Meter Acquisition
The power meter level is refreshed in real time and can help you to decide
if an iOLM acquisition is required to identify the cause and location of a
problem. You can select the power meter wavelength from the list of
available wavelengths.
Note: The OPM tab will not be available if no power meter is available in the
module.
Note: The wavelengths depends on the iOLM module.
If no wavelength is selected, you cannot perform a power meter
acquisition.
To perform a power meter acquisition:
1. Select the OPM tab.
2. Select the wavelength(s) at which you want to measure the power
levels.
The power levels are displayed for the selected wavelength in the OPM
tab.
