      ● The Advantest Q8347 is an optical spectrum analyzer employing a Michelson interferometer
      ● High resolution wavelength measurement of 0.01nm at 1.5μm band and 0.001nm at 0.5μm band
      ● Coherent length can be measured
       The coherent length, which cannot be measured by dispersion spectroscopy using a grading based spectrum analyzer, can be measured by Q8347 using the Michelson interference method.  Therefore, the Q8347 can easily determine the noise suppression performance of the CD/VD laser diode due to the reflected light. The analysis range is as wide as +/-165mm.
      ● High-speed measurement
      As the analyzer employs Fourier spectroscopy using Michelson interferometer, high speed measurement is realized.
      ● +/-0.01nm wavelength measurement accuracy
      As a He-Ne laser is used as internal reference light source, a high wavelength accuracy of 0.01nm is realized. Wavelength calibration is not required.
      ● Easy operation
      Various aspects have been taken into consideration to make measurement easier. The panel key arrangement, Soft-key menus and basic key function can be specified in the first hierarchy.  The Q8347 has a built-in level meter which greatly facilitates adjustment of the measurement light coupling.
      ● Zoom function
      The measurement data can be analyzed again and displayed with the zoom function.  Data can be displayed from wide to narrow span without repeating measurement.
      ● Various processing functions
      They include four types of FWHM measurement function, an automatic peak search function, four types of cursor indication modes, a peak value sting function and 16 data memory areas.
      ● Built-in high-speed printer
       Measurement data can be easily output using a high-speed thermal printer having a printing speed of less than 8 seconds.
