The Q8384 is an optical spectrum analyzer of the spread spectral method using the di ffraction grating mono­ chromator. The features of the optical spectrum analyzer are as follows: ( 1 ) (2) Performance compii ant with optical communication devices such as EDF A, AW G and the fiber grat­ ing. • Wavelength resolution: 10 pm or higher • Wide dynamic range: 60 dB or more • High wavelength accuracy: ±20 pm • Polarization dependency: ±0.05 dB WDM analysis function Using the EDFA analysis function (with WDM) and the relationships between wavelengths and lev­ els are easily observed by displaying a list of wavelengths. (3) Optical connectors that can be replaced by the user Users can easily replace optical connector types FC, SC and ST. (4) Operability and a large-size color LCD Measurements are taken easier than earlier models by use of operability-minded panel key arrange­ ment and soft menus. In addition, the display is now of an 8.4-inch high-intensity TFT color LCD to offer you more visibility. (5) Printer output A high-speed thermo-sensitive printer is equipped as standard to output the screen data. Further­ more, the optical spectrum analyzer is equipped with a port which is used for a printer format ESC/ P, ESC/P-R or PCL. (6) 3.5-inch floppy disk drive This drive is used to save measurement data and set conditions. The measurement data is saved in text format. This data, however, can be saved in bitmap format as screen image so that you can ana­ lyze it or make reports on an external computer.
