The Advantest Q8347 is a high-performance Optical Spectrum Analyzer (OSA) designed for the evaluation of Wavelength Division Multiplexing (WDM) transmission systems, ultra-high-speed optical transmission networks, and narrow-band optical filters. Utilizing a Fourier spectrum system based on a Michelson interferometer, the Q8347 overcomes the limitations of narrow measuring spans and low wavelength accuracy typical of Fabry-Perot interferometer systems, offering exceptional wavelength resolution and measurement accuracy across its operating range.
