ADVANTEST/Q8347/光譜分析儀
詳細資料：
● 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.
