Ando Yokogawa Optical Spectrum Analyzers

Ando Yokogawa optical spectrum analyzers, including the AQ6370B, AQ6373, AQ6317B, and AQ6331, measure wavelength, power, and spectral density across benchtop and portable formats for telecom testing, R&D, and laser characterization. GS Test Equipment stocks used and refurbished units from Ando Yokogawa, Anritsu, Keysight/Agilent, and Advantest, each tested before shipping and available to buy or rent; we also repair and calibrate these analyzers, so request a quote.
