2 Using the 86122C
Introduction
The Keysight 86120D and 86122C Multi-Wavelength Meters measure the
wavelength and optical power of laser light in the 1270–1650 nm
wavelength range (700-1700 nm for 86120D). Because the instruments
simultaneously measure multiple laser lines, you can characterize
dense-wavelength-division-multiplexed (DWDM) systems and the multiple
lines of Fabry-Perot lasers.
With the multi-wavelength meter you can quickly and easily measure the
following parameters:
• Up to 1000 laser lines simultaneously
• Wavelengths and powers
• Average wavelength
•Total optical power
• Laser line separation
• Laser drift (wavelength and power)
• Optical signal-to-noise ratios
• Fabry-Perot lasers
This chapter gives you an overview of the front and rear panel, and the
graphical user interface. In addition, it explains the steps required to make
a measurement.
