Frequently Asked Questions
- What does the Anritsu MS9740B measure and what is its wavelength range?
- The MS9740B is a benchtop optical spectrum analyzer that measures optical power across wavelengths from 600 nm to 1750 nm, covering visible through near-infrared bands. It delivers a dynamic range of 42 dB to 70 dB with switchable resolution from 0.03 nm to 1 nm, making it suitable for characterizing laser lines, WDM signals, and broadband sources in telecom and research applications. Power measurements span −90 dBm to +23 dBm, enabling analysis of both weak and high-power optical signals.
- What is the condition of this used MS9740B and what has been verified?
- We list this unit as used, meaning it has prior operational history but remains functional and ready for deployment. Before listing, we verify core functionality including wavelength accuracy, power measurement capability, and display responsiveness to ensure you receive a reliable instrument. Calibration is not included in the sale price but is available separately starting at $450 to restore full metrological traceability.
- Does this MS9740B need calibration and what does it cost?
- The MS9740B benefits from periodic recalibration to maintain measurement accuracy, particularly if you require the ±20 pm wavelength accuracy (standard option MS9740B-002). We offer calibration services separately starting at $450; I recommend contacting us directly for a quote that includes your specific accuracy requirements and current turnaround times. Calibration documentation and a certificate of conformance are provided upon completion.
- What interfaces and connectivity options does the MS9740B have?
- The MS9740B supports GPIB (IEEE 488) and RS-232 interfaces for remote control and data logging, enabling integration into automated test systems. USB connectivity is also available on this model to interface with modern computers and measurement software. Compatible drivers and control software documentation are typically included or available from Anritsu; contact us to confirm software package availability with your specific unit.
Anritsu MS9740B — Repair & Calibration Service
