This unit
The Keysight/Agilent 71452B is a diffraction-grating-based optical spectrum analyzer engineered for precise spectral characterization across the optical communications band. It measures optical power versus wavelength with high resolution, enabling detailed analysis of amplifiers, LEDs, DFB lasers, and Fabry-Perot lasers. This module integrates into the 70000 series Modular Measurement System (MMS) and pairs with a color display mainframe for integrated optical testing.
