Ando AQ6315E Optical Spectrum Analyzer – Precision Service, Expert Repair & Certified Calibration

We provide specialized repair, calibration, and maintenance services for the Ando AQ6315E Optical Spectrum Analyzer (OSA) — a highly accurate instrument designed for high-resolution optical testing in fiber optics, telecommunications, and photonics research. Known for its broad wavelength range, superior dynamic range, and advanced measurement capabilities, the AQ6315E remains a workhorse in many labs. If your unit is underperforming, displaying errors, or showing signs of wear, our experienced technicians can restore it to full working condition with precision and care.

Full Repair & Calibration Process

Comprehensive Functional Evaluation
Each AQ6315E unit is carefully tested upon arrival using calibrated light sources and test signals to assess:

  • Wavelength accuracy and drift over the 400–1750 nm range

  • Optical power measurement and signal sensitivity

  • Resolution bandwidth functionality and signal trace response

  • Sweep time accuracy and span control

  • Front panel responsiveness, GPIB/RS232 communication, and display health

We replicate real-world testing conditions using advanced equipment to identify any issues with signal stability, trace repeatability, or alignment.

Common Issues We Resolve

  • No signal detection or unstable optical readings

  • Incorrect or drifting wavelength output

  • Slow, stuck, or failed sweep mechanism

  • Grating motor or encoder issues

  • Failing display (dim, flickering, or dead screen)

  • Input port damage (FC/APC, SC/APC)

  • Internal fiber path contamination or power loss

  • Boot-up failures or system error messages

Board-Level Repair & Component Replacement
We perform deep electronic diagnostics, identifying failed components at the board level. This includes replacing damaged capacitors, voltage regulators, ICs, relay circuits, sweep drivers, and CRT or LCD controller boards. We address both analog and digital circuit faults to restore full functionality.

Grating and Optical Path Realignment
A misaligned optical path can lead to inaccurate measurements. We recalibrate the grating mechanism and internal monochromator, clean and adjust optical lenses and mirrors, and verify optical alignment to minimize insertion loss and ensure consistent measurement performance.

Display & Interface Restoration
For AQ6315E units with display issues, we repair or replace failing CRT or LCD screens, ensuring brightness, contrast, and sharpness are restored. Front panel knobs, buttons, and interface boards are also repaired or replaced as needed.

System Diagnostics & Firmware Testing
Internal self-test routines are performed to validate the unit’s performance. Firmware and EEPROM values are checked for integrity, and we ensure the system boots cleanly without error.

NIST-Traceable Calibration
After repair, each unit is fully calibrated using NIST-traceable reference sources, including:

  • Wavelength calibration with reference lasers

  • Optical power level accuracy and linearity

  • Noise floor validation and RBW accuracy

  • Sweep and span performance
    You’ll receive a calibration certificate with detailed before-and-after results.
