Changing The Port; Enabling Signal Modulation; Auto-Lambda Mode - Viavi OLS-34 Operating Manual

OLS-34/-35/-36/-37/-38

Changing the port

Note: Available for the OLS-36 only.
The OLS-36 provides two optical ports (A and B), of which only
one is selected. All device settings and displays refer to the
selected port.
To change the port:
► Press and hold down [] for more than 2 sec. to change the
port.
Notes:
• The settings of the deselected port are retained.
• Due to safety reasons all lasers or LEDs are deactivated when
changing the port.

Enabling signal modulation

Modulation frequencies provided by the OLS-34/-35/-36/-37/-
38:
• CW: continuous wave
• 270 Hz modulation
• 1 kHz modulation
• 2 kHz modulation
To select a modulation frequency:
√ Modulation cannot be changed manually when Auto-
is activated. You first must disable Auto- (see
► Press [MOD] to skip through the available modulation modes:
CW  270kHz  1kHz  2kHz  CW...

Auto-Lambda mode

Auto- is a special feature developed by Viavi that allows you to
identify wavelengths automatically. To do this, the signal is
modulated at a certain frequency, which can be detected by an
Auto- equipped power meter (such as the Viavi OLP-3x-series).
To activate Auto-:
► Press [Auto-] to skip through the modes and select the Auto-
 mode.
The display shows AUTO- .
