The MS9740A is a benchtop optical spectrum analyzer covering 600 nm to 1750 nm. The MS9740A 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.
The Optical Spectrum Analyzer MS9740A reduces the total time from waveform sweeping to data transfer to external control equipment and supports simple analysis procedures, offering excellent cost performance and better productivity.

Notes:
*1: Using SM fiber (ITU-T G.652), after 2 hours of warm-up (the Repeat sweeping performed at Span 100 nm or more and VBW 10 kHz or more during the warm-up operation), after Auto Align, at stable room temperature.
*2: Built-in option 002, after Wl cal (ref) wavelength calibration execution, at stable room temperature.
*3: 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 (50 μm/125 μm) with a return loss of >40 dB, or GI fiber (62.5 μm/125 μm) with a return loss of >38 dB.
*4: Built-in MS9740A-002, after Wl Cal (Ref), with SM fiber.
