Wavelength
The wavelength button 1 toggles through the available calibration wavelengths and
source selection depending on the mode of the instrument.
OPM Mode: The measurement wavelengths for the OP850 are 850nm, 1300nm,
1310nm, 1480nm, and 1550nm for InGaAs detectors and 489nm, 650nm, 850nm,
980nm, and 1080nm for silicon detectors, unless otherwise noted.
IL Mode: The wavelength button toggles the source wavelength concurrently with the
power meter calibration wavelength. For OP850 with a single wavelength source there
is no wavelength to be selected, for dual wavelength implementations the wavelength
selection switches between the two sources.
Source Mode: The wavelength button toggles the source wavelength.
dB/dBm
For OPM Mode: The dB/dBm button 2 switches the power meter into relative
measurement mode. At the same time it stores the current absolute power reading at
the current wavelength as the reference. The reference power is displayed above the
relative power reading (see illustration of Display). If the instrument is already in relative
measurement mode pressing the dB/dBm button stores the current power level as the
new reference. For each wavelength a reference reading can be stored.
