Q8344A - Advantest Optical Spectrum Analyzers





Q8344A - Advantest Optical Spectrum Analyzers

The Advantest Q8344A makes use of a Fourier spectrum analysis approach based on a Michelson interferometer. Because of this, the Q8344A can measure optical coherence that cannot be obtained directly using diffraction-type optical spectrum analyzers which use monochromators to make their measurements.
