Setup and Measurements
l
Wavelength : Matches the calibrated wavelength to the signal being measured.
l
Wave ID : Detects the incoming wavelength automatically from a supported VeEX OLS. Use when
operating the OLS in continuous wave (CW) mode with or without Loop enabled.
l
dB/dBm: Switches between dB and dBm measurement units. A Green dB button shows absolute
power level in dBm. A Blue dB button measures relative power loss in dB. Set (Ref) and Enter (edit
Ref) settings allow the user to set Reference, Edit Reference and view measurements in three units:
dBm, dB, and Watts.
l
Set : Sets the reference value for the current wavelength.
l
Enter : Edit current wavelength reference value.
l
Hold : Freeze measurement to the last power or loss reading on the screen. “HOLD” appears next to
“Optical Power” when tapped. Tap Hold again to unfreeze it.
l
Acquire : Loads current measured value into the Table tab. The Table tab indicates how many new
records have been temporarily saved into memory. In manual IL test mode, the Acquire button must
be used to capture each individual reading (e.g. same fiber at different wavelengths) unless Loop is
turned on. Select the Table tab to view all results in the table. This is useful when measuring mul-
tiple fibers or testing one fiber with multiple wavelengths.
l
Zero : Recalibrates the OPM to treat current conditions as zero. Used when measurement conditions
change significantly or to re-calibrate the OPM. Make sure the cover is shut on the OPM test port
before tapping Zero . When in doubt, recalibrate prior to making any measurements, e.g, when test-
ing in cold outdoor temperatures and then moving testing into a heated building.
l
OPM Server On: Remote control feature not currently supported.
If your device is equipped with a built-in clock, the saved measurement result will have a
time stamp.
To permanently save the table of results, you must save into a test file.
