Ando AQ6317 Optical Spectrum Analyzer – Expert Repair, Calibration & Precision Service

We provide professional repair, service, and calibration for the Ando AQ6317 Optical Spectrum Analyzer (OSA) — a trusted instrument widely used for high-resolution optical signal analysis in telecom, photonics, fiber optics, and R&D labs. Known for its excellent wavelength accuracy, wide spectral range, and solid construction, the AQ6317 remains a preferred choice for both legacy and modern test environments. If your unit is malfunctioning, producing inaccurate readings, or simply due for maintenance, our experienced technicians are ready to bring it back to factory-grade performance.

Our Repair & Calibration Process

Initial Diagnostic Evaluation
Every AQ6317 unit undergoes a thorough inspection to verify all key parameters:

  • Wavelength accuracy and spectral stability

  • Optical signal detection and power linearity

  • Sweep range, resolution bandwidth, and noise floor performance

  • Display functionality and front panel responsiveness

  • Grating control and sweep motor operation

  • Input port condition and GPIB/RS232 communication status

We use calibrated light sources and simulated signals to replicate real test conditions and identify root causes of performance issues.

Common Issues We Repair

  • No optical signal detection or reduced sensitivity

  • Inaccurate or drifting wavelength readings

  • Sweep motor or grating malfunction

  • Display issues (CRT flickering, dimming, or failure)

  • Faulty front panel buttons or encoder knobs

  • Input port damage (FC/APC, SC/APC) or poor signal coupling

  • Boot-up errors, firmware freezes, or non-responsive UI

  • Internal signal noise or failing electronics

Component-Level Board Repair
Our team performs deep circuit diagnostics and component-level repair, including:

  • Replacing failed capacitors, ICs, regulators, and relays

  • Repairing analog front-end and signal detection circuits

  • Restoring power supply stability and fan control

  • CRT driver and display circuit repair for legacy models

Optical Path Realignment
We realign the internal optical system — including grating, mirrors, and fiber pathways — to restore accurate signal acquisition and wavelength tracking. Optical cleaning and alignment are performed with specialized tools to minimize insertion loss and improve signal-to-noise ratio.

Display & Interface Restoration
We repair or replace the CRT display (if equipped), ensuring proper brightness and clarity. All front panel buttons, knobs, and I/O ports are tested and repaired if needed.

System Diagnostics & Firmware Verification
The AQ6317 is subjected to full internal self-tests, and firmware parameters are checked for accuracy. We ensure error-free boot-up and full functionality before release.

NIST-Traceable Calibration
All repaired units are calibrated using NIST-traceable reference lasers and optical power sources. Calibration includes:

  • Wavelength verification and span testing

  • Optical power level and linearity

  • Sweep accuracy, RBW check, and dynamic range validation
    A calibration certificate with full performance data is included with each unit.
