Measuring Power or Loss
84 AXS-100 Series
Referencing Your Power Meter to a Source
Referencing Your Power Meter to a Source
In reference mode, your unit displays the loss
created by the fiber under test only, since it
subtracts a reference value from the measured
power.
In the figure, the reference value (-43.98 dBm) is
subtracted from the actual power measured
(-37.64 dBm).
Note: The reference value you set for each wavelength remains in memory until a
new one is set for the same wavelength, even when you turn the unit off.
To reference the power meter to a source:
1. Press Menu, select Power Meter, and then press Enter.
2. Clean the connectors properly (see Cleaning and Connecting Optical
Fibers on page 22).
3. Using one of the following methods, connect a light source to the
power meter port of your unit.
³ A single reference patchcord
³ Two reference patchcords and a bulkhead adapter
