Selecting A Wavelength; Setting The Attenuation - Viavi OLA-54 Bedienungsanleitung

5 OLA-54/-55 O

Selecting a wavelength

The sensitivity of the photo diode depends on the
wavelength. The wavelength setting of the device must
match the wavelength of the incoming signal to ensure a
correct reading.
To select a wavelength:
 Press [] to select a new wavelength.
The value is shown in the lower left display pane:
selected wavelength
The wavelengths that can be selected by pressing this
key are an extract of those contained in the internal
wavelength table (-Table).
See „Editing the Lambda-Table", page 26
how to edit this table.

Setting the attenuation

The attenuation can be adjusted between 2.00 and
60.00 dB.
 Rotate the wheel to increase/decrease the attenuation
level.
The attenuation value is not stored for the selected
wavelength. You will have to set the attenuation again if
you change the wavelength.
