Advantest Q8344A optical spectrum analyzer 350NM-1750NM
The Advantest Q8344A 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
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 Q8344A 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 10mm.
+/-0.1nm wavelength measurement accuracy
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 Q8344A has a built-in level meter which greatly facilitates adjustment of the measurement light coupling.
