Anritsu MS9740B

Optical Spectrum Analyser (OSA) MS9740A

Improved Production Efficiency Reduces Measurement and Inspection Time with the Anritsu MS9740B

The Anritsu MS9740A is a benchtop optical spectrum analyser covering 600 nm to 1750 nm. The Anritsu MS9740B offers high-performance optical resolution and high-speed measurements to support the needs of device and component manufacturers.

Waveform data can be measured and transmitted to external control equipment within 0.2s — a 5x improvement over previous Anritsu models.

This enables optical device manufacturers to reduce costs and time for testing and analysis by:
– Improving sweep speed (measurement time), and
– Accelerating data transfer to control equipment after measurement

Combine these overall improvements with the ability to do basic analysis, and the result is excellent return on investment and improved productivity.

    Measurement of passive optical devices in <0.2s(5nm) reduces total analysis time
