Ando Yokogawa AQ6315B Optical Spectrum Analyzer Repair and Calibration Services
Simbol Test Systems provides professional in-lab Ando Yokogawa AQ6315B Optical Spectrum Analyzer repair and calibration services to help maintain accurate, reliable performance for your optical test and measurement equipment. The Ando AQ6315B, now associated with Yokogawa, is a high-precision, wide-range Optical Spectrum Analyzer (OSA) formerly used in optical communications, research, and laboratory test environments. Although discontinued, it remains widely used in secondary markets and optical testing labs.
Simbol has in-depth experience with AQ6315B troubleshooting and repair, including hardware and firmware-related faults. Our repair capabilities include defective board repair, chopper motor repair or replacement, monochromator adjustment, and RF module repair or replacement. We can also investigate and resolve a wide range of error codes and error messages affecting instrument operation and measurement performance.
For this legacy Ando AQ6315B OSA, a proper service should include more than a basic limited report. Our process is designed to evaluate the real condition of the instrument, verify optical spectrum analyzer performance, and perform calibration support where applicable, including calibration memory procedures when required.
Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the unit does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding.
Traceability: Instrumentation used during this calibration is traceable to N.I.S.T. (National Institute of Standards and Technology) or C.N.R.C. (Canadian National Research Council), where applicable.
Contact Simbol Test Systems with your model number and a brief description of the issue to request a calibration quote or repair evaluation for your Ando Yokogawa AQ6315B Optical Spectrum Analyzer.

Ando Yokogawa AQ6315B Optical Spectrum Analyzer – Repair and Calibration Services
The Ando/Yokogawa AQ6315B Optical Spectrum Analyzer is a rare and highly valued instrument, especially due to its ability to measure in the visible range. As these units age, proper calibration and maintenance are essential to ensure wavelength accuracy, power stability, and long‑term reliability. Simbol provides complete calibration, evaluation, and repair services for the AQ6315B, following strict OEM specifications and industry‑standard procedures.
AQ6315B Evaluation and Diagnostic Services
Send us your AQ6315B for a full evaluation. Once the diagnostic is completed, you will receive a detailed report with our findings and recommendations. In many cases, a calibration with updated calibration tables is all that is required. If repairs are needed, we will provide a complete repair quotation before proceeding.
Important: We only support AQ6315B units equipped with two fans on the back panel.
After repair, your OSA is returned fully calibrated with all relevant calibration data. Given the scarcity and high demand of the AQ6315B, restoring your unit is almost always worthwhile.
