Yokogawa AQ6370C Optical Spectrum Analyzer – Expert Repair, Optical Realignment & NIST-Traceable Calibration

We provide specialized repair, calibration, and maintenance services for the Yokogawa AQ6370C Optical Spectrum Analyzer, one of the most advanced OSAs used in DWDM, CWDM, laser testing, fiber optic communications, and photonics R&D. Known for its wide dynamic range, fast sweep speeds, and high wavelength resolution, the AQ6370C is a critical instrument in labs, production lines, and telecom test environments. If your unit is displaying errors, failing optical tests, or no longer functioning correctly, our expert team can restore it to full operational condition with factory-level precision and NIST-traceable calibration.

Our Complete Service & Repair Process

Full Diagnostic Evaluation
Each AQ6370C unit undergoes a detailed evaluation using certified tunable lasers, calibrated power meters, and reference sources to test:

  • Wavelength accuracy across the full range (600–1700 nm)

  • Dynamic range and sensitivity at various levels

  • Sweep time, resolution bandwidth, and span accuracy

  • Trace repeatability and signal stability

  • Input port performance and coupling alignment

  • Display, keypad, touchscreen (if equipped), and system boot

  • GPIB, Ethernet, and USB interface functionality

Common Issues We Repair

  • No optical signal detected or weak signal sensitivity

  • Incorrect wavelength readings or drift over time

  • Internal noise floor elevation or unstable trace

  • Slow or failed sweep functions

  • Unit not booting, freezing during startup, or showing firmware errors

  • Faulty input connectors (FC/APC, SC, LC) or damaged ports

  • Communication interface failure (LAN/GPIB/USB)

  • Display screen issues or touch panel malfunctions

  • Internal fan, temperature sensor, or power supply failures

Component-Level Electronic Repair
We perform in-depth circuit board-level repairs, including:

  • Replacement of faulty capacitors, regulators, logic ICs, and signal amplifiers

  • Repair of detector boards, sweep control circuits, and signal processing modules

  • Power supply restoration and fan control diagnostics

  • Repair or replacement of USB/GPIB/LAN interface boards

Optical System Realignment & Cleaning
Precision wavelength measurement relies on a clean and well-aligned internal optical system. Our service includes:

  • Cleaning and recalibrating fiber input ports, collimators, lenses, and mirrors

  • Re-aligning the internal monochromator and diffraction grating assembly

  • Testing and optimizing optical signal paths for minimal insertion loss and maximum dynamic range

Firmware Validation & Functional Tests
We validate system firmware, perform internal diagnostics, and test all core measurement functions, ensuring:

  • Proper trace capture and repeatability

  • Correct auto-sweep and auto-scaling behaviors

  • Fast and error-free operation across all measurement ranges

  • Remote command support and software control compatibility

NIST-Traceable Calibration
After completing repairs, each AQ6370C is calibrated using NIST-traceable optical reference sources, ensuring:

  • Certified wavelength accuracy

  • Power measurement linearity and repeatability

  • Dynamic range, resolution bandwidth, and span performance
    A calibration certificate with before-and-after data is included for compliance and documentation.
