Description

The Keysight 81560A and 81561A are small and cost effective attenuator modules with high resolution. The Keysight 81566A and 81567A feature power control functionality that allows setting the output power level directly. When the power control mode is enabled, the module automatically corrects power changes at the input to maintain the output level set by the user.
