The Optical Spectrum Analyzer (OSA) MS9740B combines high-end measurement-sensitivity performance, expanded functionality, compact size, and high-speed measurement capability. With the MS9740B, design and manufacturing engineers can accurately verify and improve time-to-market of 100G/400G optical modules designed into 5G and Cloud communications systems.
To improve measurement speed by 50%, Anritsu enhanced the optical receiver 
bandwidth settings of the MS9740B. This design approach significantly improves throughput while maintaining high performance. The benchtop OSA has wide dynamic range of >70 dB and maximum measurement processing time of 0.35s (sweeping 30-nm wavelength). Optical sensitivity is as low as –90 dBm. Accurate side mode suppression ratio (SMSR) measurements can be made at 45 dB or more, helping engineers have confidence in their designs.
The MS9740B is designed for high-throughput production environments. It supports multimode fiber input and is a candidate for manufacturing and evaluating 850-nm band VCSEL modules. Its wide wavelength range of 600 to 1,750 nm, however, makes the OSA well suited for evaluating all active optical devices. Nine application measurement modes – including LD-Module, DFB-LD, FP-LD, LED, PMD, WDM, Optical Amplifier (NF and Gain), and WDM Filter – are supported by the MS9740B, making it well suited for high-volume manufacturing.
Verification of high-speed optical devices is simplified with the MS9740B. All measurement modes can be easily accessed via intuitive menu screens. Further simplifying device verification is that the OSA supports all-at-once measurements of key evaluation items, such as optical center wavelength, level, OSNR, and spectrum line width, with results displayed on a single screen.
