Agilent 86142A & 86142B Optical Spectrum Analyzer – Expert Service, Precision Repair & NIST-Traceable Calibration

We provide professional repair, maintenance, and calibration services for both the Agilent 86142A and 86142B Optical Spectrum Analyzers (OSA) — high-performance instruments widely used in DWDM, photonics, and fiber optic test environments. Designed for high dynamic range and precise wavelength measurements across a broad spectrum, these analyzers are essential tools for R&D labs, network manufacturers, and optical component testing. Our skilled technicians specialize in diagnosing and restoring these units to factory-level accuracy using advanced tools and procedures.

Full-Service Process – From Diagnosis to Certified Calibration

Thorough Diagnostics & Functional Testing
Each incoming 86142A or 86142B is subjected to a full diagnostic evaluation. We verify:

  • Wavelength accuracy over the 600–1700 nm range

  • Optical power readings and linearity

  • Trace repeatability, span sweep, and resolution bandwidth

  • Input port condition and optical alignment

  • Grating motor performance and stability

  • Front panel and display functionality

Advanced tunable lasers and calibrated reference sources are used to simulate real test conditions and capture any irregularities or failures.

Typical Problems We Repair

  • Loss of optical signal or degraded sensitivity

  • Inaccurate or drifting wavelength measurement

  • Internal grating assembly failure or misalignment

  • Burnt or worn fiber input connectors (FC/APC, SC/APC)

  • Boot-up issues, firmware freezes, or error codes

  • Damaged front panel knobs, buttons, or displays

  • Power supply instability or noisy internal fans

Component-Level Electrical & Optical Repair
We perform deep-level circuit board troubleshooting to repair or replace failed ICs, capacitors, relays, sensors, and voltage regulators. Optical assemblies are cleaned, re-aligned, and re-centered using factory-grade alignment protocols to recover signal integrity and trace stability.

Monochromator & Grating Alignment
We precisely align the internal monochromator, stepper motors, and grating control assemblies to restore optimal scan accuracy and noise floor. This ensures proper spectrum trace, peak detection, and consistent readings across sweeps.

Self-Test Diagnostics & Firmware Validation
Our repair process includes running full internal diagnostics and checking firmware integrity. Where supported, firmware is updated to improve performance and resolve legacy bugs.

NIST-Traceable Final Calibration
All units receive a certified calibration using NIST-traceable reference sources, which includes:

  • Wavelength accuracy verification with standard lasers

  • Optical power level accuracy testing

  • Noise floor and RBW validation

  • Sweep speed and span verification
    A calibration certificate is provided with detailed before/after performance metrics.
