● The Advantest Q8347 is an optical spectrum analyzer employing aMichelsoninterferometer● High resolution wavelength measurement of0.01nmat1.5μmband and0.001nmat0.5μmband● Coherent length can be measuredThe 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 measurementAs the analyzer employs Fourier spectroscopy using Michelson interferometer, high speed measurement is realized.● +/-0.01nm wavelength measurement accuracyAs 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 operationVarious 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 functionThe 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 functionsThey 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 printerMeasurement data can be easily output using a high-speed thermal printer having a printing speed of less than 8 seconds.Specification Wavelength 350nm - 1750 nm Resolution 0.001nm / 500nm (high resolution mode) 0.003nm / 850nm (high resolution mode) 0.01nm / 1550nm (high resolution mode)0.05 nm / 850nm (normal resolution mode)0.1 nm / 1550nm (normal resolution mode)Wavelength Accuracy ±0.01 nm or less(high resolution mode) ±0.1 nm or less (normal resolution mode) Span 0.01nm /DIV to 140nm/DIVInput Sensitivity -72 dBm to +10 dBm (1.2μm to 1.6 μm)-65 dBm to +10 dBm (0.7μm to 1.6 μm)-52 dBm to +10 dBm (0.45μm to 1.7 μm)-42 dBm to +10 dBm (0.35μm to 1.7 μm) Level accuracy ±1.0dB (780nm), ± 0.7dB (1310,1550 nm)Dynamic range 35dB or moreRepeatability including polarization dependence±0.1dB or less at 1550nmLevel scale 0.2, 0.5, 1.0, 2.0, 5.0, 10.0 dB/DIV and linearMeasurement time 1 second or lessMemory function 16screens ( measurement data) with battery backup10 screens (measurement condition) with battery backupFloppy disk (MS-DOS format: 720KB / 1.2 MB) Display Frequency, superimpose, 3-dimensional trend monitor (power,Wavelength), dual screen (up/down) display, cursor function,Color display customization, ListingCalculation Analysis ●Spectrum analysis ●Coherence analysis ●Spectral half-widthCalculation ●Averaging ●Automatic optimum measurement●Smoothing ●Automatic peak search ●Normalizing ● CurveFit ● MAX/MIN holdOptical Input connector FC connectorData Output ●GPIB Standard equipment ● direct plotter ● Built-in printerExternal Dimensions Main unit: 424(W) X 221(H) X 500(D) mmOptical unit: 424 (W) X 132(H) X 500(D) mm Mass Main unit: about 16 KgOptical unit about 20 Kg
