Frequently Asked Questions
- What does the Anritsu MS9740A measure, and what is its wavelength range?
- The MS9740A is a precision optical spectrum analyzer designed to measure optical power across a wavelength range of 600 nm to 1750 nm, covering visible through near-infrared bands. It delivers a dynamic range of 58 dB at 0.4 nm resolution (standard) with wavelength accuracy of ±20 pm in the 1520–1620 nm C-band region. The instrument's power measurement capability spans –90 to +10 dBm, making it suitable for characterizing WDM systems, ASE, and broadband optical sources in telecom and research applications.
- What condition is this used MS9740A in, and what was verified before listing?
- This unit is offered in used condition and has been power-tested to confirm basic operational status. We verify that the instrument powers on and responds to commands; however, we recommend obtaining a full calibration to validate measurement accuracy against your application requirements. Calibration services are available separately and documented through our service partners.
- What does calibration cover for the MS9740A, and what is the cost and timeline?
- Calibration for the MS9740A typically verifies wavelength accuracy, power linearity, and dynamic range performance against NIST-traceable standards. We offer calibration services starting at $450, which covers the standard measurement parameters for this model. Turnaround time and specific scope details are provided upon quote; contact our sales team for current lead times and service options.
- What interfaces and connectivity options does the MS9740A support?
- The MS9740A includes GPIB (IEEE-488) connectivity for remote instrument control and data acquisition, enabling integration into automated test systems and lab environments. The instrument is compatible with Anritsu's proprietary software and standard GPIB drivers available for Windows and Linux platforms. For detailed driver compatibility and software version information specific to your control system, we recommend consulting the original user manual or contacting Anritsu technical support directly.
