Keysight 8157xA Variable Optical Attenuator modules / 214
How to Use a Variable Optical Attenuator module / 216
This chapter explains how to use the 8163A/B Lightwave Multimeter,
8164A/B Lightwave Measurement System, or 8166A/B Lightwave
Multichannel System together with the 8157xA family of Variable Optical
Attenuator modules to attenuate and control optical power in single-mode
optical fibers.
Here you will find:
• A brief description of the modular Keysight 8157xA Variable Optical
Attenuator family,
• A description of how to use these modules, including applying an
attenuation factor, setting an output power, applying offset factors,
constructing a
λ offset table, and (for the 81576A and 81577A) using
the power control feature.
