Service & Repair of Agilent 86141B Optical Spectrum Analyzer OSA

Agilent 86141B Optical Spectrum Analyzer – Precision Service, Expert Repair & Certified Calibration

We offer specialized repair, calibration, and refurbishment services for the Agilent 86141B Optical Spectrum Analyzer (OSA) — a high-performance optical test instrument widely used in DWDM, fiber optic, and photonics applications. Known for its exceptional resolution bandwidth, dynamic range, and wavelength accuracy, the 86141B plays a vital role in optical network development, manufacturing, and lab research. Our team of experienced engineers ensures each unit is fully restored, tested, and calibrated to meet or exceed original factory specifications.

Our End-to-End Repair Process

Comprehensive Diagnostics & Evaluation
Each 86141B unit goes through a multi-step evaluation process where we test:

• Wavelength accuracy across the full 600–1700 nm range

• Optical power level response and linearity

• Grating motor movement and step resolution

• Display performance and control panel responsiveness

• Power supply voltages and internal board-level health

Advanced tunable lasers and optical sources are used to simulate real-world input signals, helping us identify any instability, drift, or component failure.

Frequent Issues We Repair

• No or low optical signal detection

• Incorrect wavelength or spectrum reading

• Optical drift or unstable traces

• Grating motor or encoder malfunction

• Failing or unresponsive display

• Front-panel knob and key failures

• Crashes during boot or stuck on firmware

• Damaged fiber input connectors (FC/APC, SC/APC)

Board-Level and Component Repair
We perform detailed electronic and mechanical repair down to the component level. Whether it’s a failed capacitor on the power board, a damaged A/D converter, or faulty optical sensors, we replace components using precision soldering, manufacturer-grade parts, and thorough post-repair verification.

Monochromator Alignment & Optical Cleaning
Internal optics are aligned using laser-based test benches to ensure minimal insertion loss and accurate signal path geometry. We also clean fiber connectors, optical mirrors, and internal lenses to restore proper signal strength and signal-to-noise ratio.

Firmware & Internal Self-Test Validation
Units are run through full internal diagnostics, and firmware is checked or updated to ensure system stability. Any stored error logs are reviewed and cleared after functional testing.

NIST-Traceable Calibration with Certification
Post-repair, each unit is calibrated using NIST-traceable references:

• Wavelength accuracy testing using standard laser sources

• Optical power meter validation

• Verification of resolution bandwidth, span, and sweep time

• Calibration certificate with complete before/after test results provided
