Optical Spectrum Analyzer

The AQ6317B Optical Spectrum Analyzer (OSA) is an advanced optical spectrum analyzer for a wide range of applications, including light source evaluation, measurement of loss wavelength characteristics in optical devices, and waveform analysis of WDM (Wavelength Division Multiplexing) systems. It was originally manufactured by Ando, before Yokogawa purchased the product line.Features：Wavelength Range: 600 to 1750 nmDynamic Range: 60 dB (1523nm, peak 0.2nm, resolution: 0.01nm)Wavelength Accuracy: 0.5 nm (600 to 1750nm)Wavelength Linearity: 0.01nm (1520 to 1580nm)Wavelength Repeatability: 0.005 nm (1 min)Polarization Dependency: 0.05 dB (1550/1600nm), 0.05 dB typ.
