OLP-85/OLP-85P
Enabling Auto- mode
Auto is a special feature developed by Viavi that allows you to
identify wavelengths automatically (from OLS-XX, MTS-2k/4k/6k
OTDR CW-source). To do this, the signal is modulated at a
certain frequency (by a light source equipped with Auto , such
as a Viavi OLS-85), which can be detected by a Viavi OLP-85.
In Auto mode the detected wavelength will be included in the
table. As long as the detected wavelength is active, it cannot be
deleted from the table.
Wavelengths cannot be reliably detected if:
• the receive level is too low,
• wavelength encoding cannot be detected due to interference
• you are measuring the absolute level of a system that does not
have wavelength encoding matching Viavi power sources.
To switch Auto mode on/off :
The instrument is in Powermeter mode.

Displaying modulated signals
The OLP-85/OLP-85P automatically detects the modulation
frequency of light signals modulated at the fixed frequencies of
270 Hz, 1 kHz, and 2 kHz. The detected frequency is shown in
the lower right measurement display pane.
