The Advantest Q8344A is an Optical Spectrum Analyzer designed with a Michelson interferometer-based Fourier spectrum analysis approach. This unique design enables the direct measurement of optical coherence length, a capability not typically found in conventional diffraction-type monochromator spectrum analyzers. It covers a broad wavelength range of 350 nm to 1750 nm, making it highly suitable for evaluating semiconductor lasers and optical fiber components.
