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.

*1: Warm-up the instrument for at least 2 hours before measurement by performing repeated sweeping at span ≥ 100 nm, VBW ≥ 10 kHz. Perform waveform calibration after auto-optical alignment (WI Cal) and keep the instrument at the same temperature unless stated otherwise. Use either SM fiber (ITU-T G.652) or GI fiber (50μm/125μm) with a return loss of >40 dB, or GI fiber (62.5μm/125μm) with a return loss of >38 dB
