Anritsu MS9740B Optical Spectrum Analyzer

Overview

The Anritsu MS9740B is an advanced benchtop optical spectrum analyzer featuring wide dynamic range and high-speed measurement capabilities over a wavelength range of 600 nm to 1750 nm. It supports both single-mode and multimode fiber input and is ideal for manufacturing and evaluating optical devices such as VCSEL modules operating in the 850 nm band. The MS9740B reduces measurement processing times by up to 50% compared to its predecessor while maintaining measurement sensitivity.

Key Features

• Wide dynamic range with high-speed measurements at optical receiver bandwidths common in production environments
• 45 dB minimum side-mode suppression ratio (SMSR) measurement capability
• Maximum measurement processing time of 0.35 seconds for 30 nm wavelength sweep in fast mode
• Nine application menus for specialized measurements (LD-module, WDM, optical amplifiers, and more)
• Dynamic range up to 70 dB at ±1 nm from peak wavelength
• User-replaceable optical connectors (FC, SC, ST, DIN)
• Support for all optical active devices including LD-modules, DFB-LD, FP-LD, LED, PMD, WDM, optical amplifiers

Applications

• Optical active device evaluation and production testing
• VCSEL module characterization at 850 nm and other wavelengths
• Semiconductor and optoelectronics manufacturing
• Wavelength and spectral width measurements
• Optical signal-to-noise ratio (OSNR) analysis
