Anritsu MS9740B Optical Spectrum Analyzer
Featuring a wide dynamic range, high resolution, and fast sweep speeds over a wavelength range of 600 nm to 1750 nm
The benchtop Optical Spectrum Analyzer MS9740B features wide dynamic range, high resolution, and fast sweep speeds over a wavelength range of 600 nm to 1750 nm. It supports multimode fiber input and is ideal for manufacturing and evaluating 850-nm band VCSEL modules.
As well as keeping the same functions and performance as its predecessor, the MS9740B slashes measurement processing times by up to half*1 while overcoming problems of decreased measurement sensitivity caused by increased processing speed.
Moreover, it retains optical active device (LD-Module, DF-LD, FP-LD, LED, PMD, WDM, Opt Amp, and WDM Filter) measurement menu screens for evaluating devices. It supports all-at-once measurements of key evaluation items, such as optical center wavelength, level, OSNR, spectrum width, etc., and displays these results at one screen.
