Anritsu MS9740B OSA GPIB Calibrator: Compact Benchtop Optical Spectrum Analyzer for Fiber-Optic Test

The Anritsu MS9740B OSA GPIB Calibrator is a benchtop optical spectrum analyzer designed for fast, accurate spectral measurements on laser diodes, LEDs, optical amplifiers, and DWDM systems. Its diffraction-grating monochromator and high-speed sweep engine make it a practical fit for production test floors, optical component qualification labs, and R&D engineers who need OSA performance without the footprint of larger rack-based systems.

Key Features and Benefits of the Anritsu MS9740B OSA GPIB Calibrator

• 600 to 1750 nm wavelength range — Single instrument covers visible, telecom O- through L-bands, and short-wave datacom sources.
• 0.03 nm resolution bandwidth — Resolves narrow-spaced DWDM channels and fine spectral features on DFB and FP laser sources.
• High-speed sweep (under 0.2 s typical) — Cuts cycle time on production lines where every tested unit per hour counts.
• ±0.02 nm wavelength accuracy — Reliable for ITU channel verification and tunable laser characterization.
• 70 dB close-in dynamic range — Reveals sidemodes and ASE noise next to strong carriers without saturation artifacts.
• GPIB and Ethernet remote control — Integrates directly into legacy and modern automated test systems with SCPI commands.
• Built-in analysis functions — DFB, FP-LD, LED, EDFA, WDM, and OSNR routines run on the instrument without external scripting.
• Compact benchtop chassis — Fits on a crowded workbench while still delivering full-feature OSA performance.

Advanced Capabilities

The MS9740B's analysis library is what makes it more than just a graphical spectrum display. Built-in WDM analysis routines automatically identify ITU channels, compute per-channel wavelength, power, and OSNR, and produce a tabular summary in seconds. EDFA test mode separates signal from amplified spontaneous emission and reports gain and noise figure across all channels at once. For engineers who would otherwise build these calculations in MATLAB or Python from raw trace data, having the routines run on the instrument cuts both test time and the chance of analysis drift between operators.

The double-pass monochromator architecture is the other technical advantage worth calling out. A single-pass grating instrument starts to smear high-contrast spectra together — for example, an EDFA output where the signal sits 50 dB above the ASE floor a few tenths of a nanometer away. The double-pass design rejects stray light far more aggressively, which is what turns OSNR readings from estimates into measurements you can hand to a customer with confidence.

Calibration and Quality Assurance

Every Anritsu MS9740B is calibrated prior to shipping to OEM specifications. The order includes a Calibration Certificate, Calibration Label, and full Calibration Data. This means the instrument arrives traceable, audit-ready, and ready to use straight out of the box — no need to schedule a calibration cycle before putting it into service.
