This unit
The Anritsu MS9720B is a optical spectrum analyzer engineered for precise characterization of optical devices and WDM systems. Operating across the C-band, it delivers 58 dB dynamic range, -87 dBm sensitivity, and 0.03 nm minimum resolution bandwidth for detailed spectral analysis. Built-in acetylene calibration and an integrated SLD light source enable automated wavelength accuracy to ±20 pm, while multi-channel WDM analysis, NF measurement, PMD calculation, and SMSR capabilities address demanding R&D, manufacturing, and quality control workflows in optical communications.

Frequently Asked Questions
- What does the Anritsu MS9720B measure, and what is its wavelength range?
- The MS9720B is an optical spectrum analyzer designed to characterize optical signals across the C-band and L-band regions, covering wavelengths from 1450 nm to 1650 nm. It delivers wavelength accuracy of ±20 pm in the 1530–1570 nm window with a reference source, a 0.03 nm resolution bandwidth, and a 58 dB dynamic range at 1 nm offset from the signal peak. This instrument is widely used for DWDM system commissioning, fiber-optic network diagnostics, and optical component testing.
- What is the condition of this used MS9720B, and what was verified?
- This MS9720B is offered in used condition and has been functionally tested to confirm core measurement capabilities. We verify power range performance across its full span of −87 dBm to +30 dBm and confirm that wavelength and amplitude readings track within specification limits. Calibration is available separately through our service offerings if a fresh traceable certificate is required for your application.
- What does calibration cover for the MS9720B, and how much does it cost?
- Calibration service for the MS9720B begins at $450 and typically includes wavelength verification and power level accuracy across the operating range. We recommend recalibration if the instrument has not been serviced within two years or if your application requires traceable measurement certification. Turnaround time and scope details are available upon request when you contact our service team.
- What interfaces and connectivity options does the MS9720B support?
- The MS9720B features GPIB (IEEE-488) connectivity for remote instrument control and data transfer, making it compatible with automated test systems and standard laboratory software. The analyzer accepts 85–132 Vac or 172–250 Vac at 47.5–63 Hz with a maximum draw of 150 VA, and it integrates with Anritsu's proprietary measurement software via its parallel port.
