Optical Spectrum Analyzer Repair and Calibration Services

Yokogawa-AQ6370 Calibration and repair

At Aumictech Test Equipment Solutions, we specialize in Optical Spectrum Analyzer (OSA) repair and calibration for industry-leading models such as Agilent/Keysight, Ando, Yokogawa, and Anritsu. Our certified engineers combine years of experience in RF and optical test equipment to ensure that your OSA performs with the highest accuracy in wavelength, power, and resolution bandwidth measurements.

Whether you are a telecom carrier, an optical component manufacturer, or an R&D laboratory, Aumictech provides cost-effective, NIST-traceable, and on-site calibration services to keep your instruments compliant and production-ready.

Technical Advantages of Aumictech OSA Calibration

An OSA’s accuracy depends on its wavelength reference, optical input stage, monochromator system, and photodetector calibration. Over time, grating alignment, reference lamps, and detectors drift, leading to measurement errors.

Our calibration process covers:

  • Wavelength Accuracy Verification – Using stabilized lasers and gas emission lines to confirm wavelength accuracy within ±0.01 nm (or model specification).

  • Power Level Calibration – NIST-traceable optical power meters used to calibrate detector response across the full OSA dynamic range.

  • Resolution Bandwidth Testing – Verification of RBW performance for DWDM/CWDM applications.

  • Linearity Testing – Confirming consistent optical power readings across the OSA’s full measurement range.

  • Polarization Dependence Evaluation – Measuring OSA polarization sensitivity and adjusting for minimal variation.

  • Firmware/Software Recalibration – Updating internal calibration tables with verified values for accurate results.

Each unit is bench-tested against reference standards to ensure compliance with ITU-T DWDM/CWDM channel spacing requirements.

Repair Services – Beyond Calibration

Aumictech provides component-level repair for common OSA failures, including:

  • Optical Input Damage – Connector and attenuator replacements.

  • Monochromator & Diffraction Grating Issues – Realignment or replacement for wavelength stability.

  • Detector Array Failures – InGaAs/PbS detector replacement and recalibration.

  • Internal Reference Lamp Drift – Replacement of aging lamps to restore wavelength accuracy.

  • Power Supply & Control Electronics – Troubleshooting DC-DC converters, boards, and display modules.

  • Cooling and Fan Systems – Replacement to maintain temperature stability and reduce noise.

All repairs are completed with full calibration and certification, restoring instruments to factory-grade performance.

Best for Manufacturing Plants and Multi-Instrument Service

Manufacturers of optical components, transceivers, and DWDM/CWDM systems often operate multiple OSAs across production lines. Aumictech offers:

  • Bulk Calibration Discounts – Lower cost per instrument for 3+ OSAs serviced together.

  • Scheduled Plant-Wide Service Programs – Regular calibration cycles to prevent production delays.

  • Asset Tracking & Certificates – Calibration records maintained for all your OSAs for compliance with ISO 17025 and telecom industry standards.

This helps reduce cost, ensures uniform test results across multiple instruments, and keeps production compliant with customer and regulatory requirements.

On-Site Calibration and Maintenance

For facilities where equipment cannot be shipped out, Aumictech provides on-site OSA calibration:

  1. Portable Calibration Standards – Reference lasers, optical power meters, and test sources carried to your site.

  2. Multi-Unit Efficiency – Calibrating several OSAs during a single visit for lower per-unit cost.

  3. Preventive Maintenance – Cleaning optics, checking connectors, and verifying optical alignment.

  4. Compliance Certificates – NIST-traceable calibration certificates provided for audit and QA documentation.

On-site visits are ideal for optical transceiver production plants, telecom network labs, and government/defense facilities where downtime must be minimized.
