Information

The Q8347 is an optical spectrum analyzer employing a Michelson interferometer. Its main features are given below. Features • High-resolution wavelength measurement The analyzer measures wavelength with high resolution of 0.01 nm at 1.5/^m band and 0.001 nm at 0.5/дп band. Therefore, the analyzer can analyze the devices used for multi-mode light or wavelength division multiplexing that cannot be dissolve heretofore. • Coherent length can be measured. The coherent length which cannot be measured by dispersion spectroscopy using a grating can be measured by the Q8347 using the 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 an interferometer, high-speed measurement is realized. Even when the GP!B is used in system, the entire procedure from the measurement start trigger to data output can be carried out in 2.5 seconds (in the high-resolution mode) or in 1.0 second (in the normakesoiution mode). (In this case, the wavelength range is the long wavelength.) • ±0.01nm wavelength measurement accuracy As a He-Ne laser is used as the internal reference light source, a high wavelength accuracy of 0.01 nm is realized. Wavelength calibration is not required. • Easy operation Various aspects have been taken into consideration to make measurement easier. The panel key arrangement, Softkey menus and basic key functions 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 Various processing functions are available. They include four types of FWHM (full width half maximum) measurement function, an automatic peak search function, four types of cursor indication modes, a peak value listing 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.
