OptoTest OP815 - Front Panel Operation OP815

OP815
9 of 16
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 OP815 are 850nm, 1300nm,
1310nm, 1480nm, and 1550nm for InGaAs detectors and 650nm, 850nm, and 980nm
for silicon detectors, unless otherwise noted.
IL Mode: The wavelength button toggles the source wavelength concurrently with the
power meter calibration wavelength. For OP815 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.
Reference
For OPM Mode: The Ref 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 Ref button stores the current power level as the new reference. For
each wavelength a reference reading can be stored.
