General information

This chapter describes how to use the OLT-85/OLT-85P as a
power meter. In Powermeter mode up to two wavelengths can
measured simultaneously. Results can be displayed as absolute
level in dBm/Watt, relatively to a reference value in dB or as Pass/
Fail indication based on predefined limits.
More information about measuring loss with two instruments
set to source and powermeter mode can be found in the chapter
"Powermeter Operation" on page 44.

Setting and selecting wavelengths

The OLT-85/OLT-85P provides several ways to select a
wavelength:
• Auto  mode: When using an Auto  capable laser source (like
the OLS-85), wavelengths can automatically be detect.
• By tapping the wavelength displayed in the measurement
display until the desired wavelength is shown. The wavelengths
offered in the table can be defined in the [Edit
• By selecting a wavelength from the  table in the menu. The
wavelengths listed in this table are not affected by the Show
settings in the [Edit
