Advantest Q8347 optical spectrum analyzer 350NM-1750NM

Advantest Q8347 Datasheet and general information link: http:// /DataSheet/ADVANTEST/ADVAN_Q834785259.pdf
The Advantest Q8347 is an optical spectrum analyzer employing a Michelson interferometer
High resolution wavelength measurement of 0.01nm at 1.5 m band and 0.001nm at 0.5 m 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.
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.
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.
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.
Measurement data can be easily output using a high-speed thermal printer having a printing speed of less than 8 seconds.
