At Aumictech, we specialize in professional repair and NIST-traceable calibration services for the Anritsu MS9740B Optical Spectrum Analyzer — a cutting-edge tool used in optical communication, photonics R&D, and high-speed device validation. This OSA offers outstanding performance in DWDM, silicon photonics, and laser diode testing, but like all precision instruments, it requires periodic calibration and expert-level repair to maintain its world-class accuracy.
If your Anritsu MS9740B is showing performance degradation, wavelength drift, or signal detection issues, Aumictech is ready to restore it to peak factory condition with fast turnaround and certified documentation.
About the Anritsu MS9740B Optical Spectrum Analyzer
The MS9740B is the newest addition to Anritsu’s optical test platform and is highly regarded for its speed, accuracy, and broad functionality. Key features include:
- Wavelength range: 600 – 1750 nm
- Resolution bandwidth: 0.03 to 2 nm
- High dynamic range: ≥ 60 dB
- Sweep speed up to 0.2 sec (100 nm span)
- Level accuracy ±0.5 dB
- Built-in analysis for WDM, SMSR, and NF measurements
The MS9740B is a staple in next-generation optical communication system development, offering advanced features that meet the needs of modern labs working with high-speed optics, tunable lasers, and photonic integrated circuits.
Common Issues with the MS9740B – What Aumictech Repairs
Although highly advanced, the Anritsu MS9740B contains sensitive photodiodes, ADCs, motorized filters, and internal optics that degrade over time or suffer from handling errors. Common problems we resolve include:
🔧 Inaccurate Wavelength Readings
- Caused by aging optical references, environmental drift, or misalignment
- We perform traceable recalibration with gas cell and laser references
🔧 No Signal or Low Sensitivity
- Often due to dirty input optics, degraded detectors, or internal relay faults
- We clean optics, test detectors, and repair front-end circuitry
🔧 Sweep or Trigger Malfunctions
- Symptoms include jerky or non-linear sweeps, or missed peaks
- We test and replace motors, relays, and timing control boards
🔧 GUI and Firmware Errors
- Black screens, frozen UI, or memory issues can affect operation
- We reflash firmware, replace SSD/HDD, and upgrade memory modules
🔧 Burned or Damaged Optical Input Ports
- Caused by improper cleaning or high input power
- We replace connectors and realign fiber input couplers
After every repair, we perform a full sweep analysis, recalibrate, and validate the OSA to ensure it meets or exceeds original factory specs.
