Ando AQ6317B & AQ6317C Optical Spectrum Analyzer – Professional Repair, Service & NIST-Traceable Calibration

We offer expert repair, calibration, and restoration services for the Ando AQ6317B and AQ6317C Optical Spectrum Analyzers (OSA)—industry-standard tools trusted by optical labs, telecom equipment manufacturers, and photonics researchers. These models are known for their exceptional wavelength accuracy, wide dynamic range, and fine resolution bandwidth control. Whether you’re dealing with signal inconsistencies, drift, display issues, or full system failure, our skilled technicians can restore your unit to factory performance standards.

Detailed Repair & Calibration Workflow

Full Diagnostic Evaluation
Each AQ6317B or AQ6317C that enters our facility undergoes a multi-stage evaluation using calibrated optical sources and tunable lasers to test:

  • Wavelength accuracy across 600–1750 nm

  • Optical power linearity and sensitivity

  • Sweep speed, resolution bandwidth, and signal response

  • Grating motor and sweep drive operation

  • Display output and front panel response

  • Communication interfaces (GPIB/RS232)

  • Internal temperature regulation and system stability

We simulate real-world conditions to capture both obvious and subtle hardware or optical path issues.

Common Issues We Fix

  • No signal detection or erratic trace behavior

  • Wavelength drift or incorrect measurements

  • Internal noise or degraded signal-to-noise ratio

  • Sweep motor failure or grating movement issues

  • CRT or LCD screen dimming, flicker, or failure

  • Power supply instability, reboots, or shutdowns

  • Input port damage or poor fiber coupling

  • Boot-up errors, system lockups, or failing firmware

Precision Electronics & Optical Repair
We perform component-level repairs on all major internal subsystems:

  • Analog front-end signal circuits

  • A/D converters and digital processors

  • Sweep and grating control boards

  • Power supply modules and fan controllers

  • CRT or LCD driver circuits

All repairs are followed by performance testing under varying conditions.

Optical System Realignment & Cleaning
Internal optics are thoroughly cleaned, realigned, and recalibrated. We service the monochromator, fiber couplers, mirrors, and diffraction gratings to restore optimal alignment, reduce insertion loss, and ensure repeatable trace quality.

Firmware & Functional Testing
After repairs, we validate firmware and configuration parameters, run built-in self-tests, and confirm that all UI elements and automation functions (e.g., remote control via GPIB) operate correctly.

NIST-Traceable Final Calibration
Using certified reference lasers and optical power sources, we perform a complete NIST-traceable calibration, including:

  • Wavelength accuracy testing

  • Optical power level calibration and linearity verification

  • Resolution bandwidth, sweep time, and dynamic range checks
    Each unit is delivered with a detailed calibration certificate showing pre- and post-repair data.
