Keysight 86120D and 86122C Multi-Wavelength Meters User’s Guide

Getting Started

Fabry-Perot Lasers

Fabry-Perot lasers can be easily measured by using the Fabry-Perot Laser

application.

Press and

click

Power Greater than 10 dBm

The maximum total input power that can be measured is 10 dBm.

However, with the addition of an external attenuator, more power can be

applied.This may be necessary at the transmit end of a

wavelength-division multiplexed system where large signal levels are

present. By entering a power offset equal to the amount of attenuation at

the instrument’s input, accurate amplitude measurements are shown on

the display.
1 Connect an optical attenuator between the front-panel OPTICAL

INPUT connector and the fiber-optic cable from your device. The

attenuator must reduce the total input power to the Keysight

multi-wavelength meter so that it is below +10 dBm.

2 Press and

click

3 Click the Power Offset tab.
4 Click the Power Offset box, and enter a power offset value.
5 Click Close.

Power offset values are added to the display power readings. For example,

if you placed a 10-dB attenuator on the front-panel connector, you should

enter a power offset value of +10 dB. Negative values can also be entered

if you connect an amplifier instead of an attenuator.
