Display Operation – OP815/OP850
Depending on the selected mode the display shows different measurement parameters
and results.
Wavelength
This label displays the currently selected calibration wavelength of the source wavelength
used to measure optical power. Typically the wavelengths are as follows:
OPM Mode: 850nm, 980nm, 1300nm, 1310nm, 1480nm, 1550nm
IL Mode: Multimode 850nm, 1300nm; Single Mode 1310nm, 1550nm
Absolute Power
The absolute power is displayed in dBm.
Relative Power
The relative power is displayed in dB. It is the difference between the reference power
at the corresponding wavelength and the measured absolute power.
Internal Temperature
The internal ambient temperature is displayed in either ºF (Fahrenheit) or ºC (Celsius).
The user can alternate between Fahrenheit or Celsius temperature scales by the
implementation of a USB command.
