Service & Repair of HP 70950A Optical Spectrum Analyzer OSA

The HP 70950A Optical Spectrum Analyzer (OSA) module integrates with the HP 70004A mainframe to deliver precision spectral analysis across the 600 nm to 1700 nm range. This diffraction-grating-based instrument measures optical power versus wavelength with high amplitude and wavelength accuracy while remaining polarization insensitive. The double-pass monochromator design achieves high dynamic range performance comparable to double-monochromator systems, combined with single-monochromator sensitivity. Ideal for characterizing optical components, amplifiers, LEDs, DFB lasers, and Fabry-Perot lasers, the HP 70950A operates as the HP 71450A when paired with its mainframe in the Hewlett-Packard Modular Measurement System (MMS) platform.
