Yokogawa AQ6370E Optical Spectrum Analyzer – Expert Repair, Precision Realignment & NIST-Traceable Calibration

We provide specialized repair, calibration, and maintenance services for the Yokogawa AQ6370E Optical Spectrum Analyzer, the latest generation in Yokogawa’s renowned AQ6370 series. Designed for ultra-accurate optical signal analysis across telecom, photonics, DWDM, CWDM, and fiber optic component testing, the AQ6370E is known for its exceptional wavelength accuracy, fast measurement speed, and wide dynamic range. Whether your unit is showing trace instability, boot failure, or incorrect measurements, our expert technicians restore it to like-new performance with precision diagnostics and NIST-traceable calibration.

Comprehensive Service & Calibration Workflow

Full System Diagnostics & Evaluation
Each AQ6370E unit is carefully evaluated using certified tunable lasers, optical sources, and reference tools to assess:

  • Wavelength accuracy and measurement stability across the 600–1700 nm range

  • Trace repeatability, span control, and resolution bandwidth performance

  • Optical input port functionality and fiber coupling efficiency

  • Noise floor performance and dynamic range validation

  • Display screen and touchscreen response

  • GPIB, USB, and Ethernet communication interface functionality

  • Boot-up performance and system diagnostics

Common Issues We Repair

  • No signal or low sensitivity on the optical input

  • Wavelength drift or incorrect spectrum data

  • Frozen display, boot-loop errors, or unresponsive touchscreen

  • Communication port failures (LAN/USB/GPIB)

  • Internal fan or temperature sensor failure

  • No sweep or unstable trace pattern

  • Damaged FC/APC, SC, or LC input connectors

  • Power supply irregularities or shutdown during use

Component-Level Repair & Electronics Servicing
We conduct detailed board-level diagnostics and component replacement, including:

  • ICs, op-amps, voltage regulators, and analog signal processors

  • Power supply unit repair and cooling system restoration

  • Detector board repairs and amplifier stabilization

  • USB/LAN/GPIB interface repairs for remote communication

Optical System Cleaning & Realignment
Accurate spectral performance depends on perfectly aligned optics. We perform:

  • Cleaning and adjustment of collimators, fiber ports, internal lenses, and diffraction gratings

  • Recalibration of the monochromator and beam path to factory standards

  • Optical path testing for loss, alignment, and peak detection

Firmware & Functional Testing
Post-repair, we run all firmware diagnostics and verify:

  • Full sweep and auto-range functionality

  • Remote software connectivity and scripting/API response

  • Menu control, touchscreen responsiveness, and system health indicators

NIST-Traceable Calibration & Certification
After all repairs and alignments, each AQ6370E undergoes NIST-traceable calibration, including:

  • Wavelength accuracy testing using certified reference lasers

  • Power measurement linearity and stability checks

  • Sweep time, RBW, and noise floor validation
    A full calibration certificate with pre- and post-repair test results is provided with the unit.
