Service & Repair of Agilent 86146B Optical Spectrum Analyzer OSA

Agilent 86146B Optical Spectrum Analyzer – Professional Repair, Precision Service & NIST-Traceable Calibration

We offer expert repair, calibration, and maintenance services for the Agilent 86146B Optical Spectrum Analyzer (OSA) — a high-end instrument trusted by optical engineers, telecom manufacturers, and photonics labs for its superior performance in DWDM and broadband optical testing. Known for its wide dynamic range, high wavelength accuracy, and built-in tunable laser source, the 86146B plays a vital role in network development, component testing, and R&D. Our skilled team ensures your analyzer is restored to its original performance standards through deep technical evaluation, optical alignment, and certified calibration.

Our Proven Service Workflow

Comprehensive Diagnostic Evaluation
Each 86146B undergoes full system diagnostics to identify functional or signal-related faults. We test:

• Wavelength accuracy and stability across the full range

• Optical signal level and dynamic range

• Resolution bandwidth performance

• Tunable laser output (if included)

• Display and user interface functionality

• Input connectors and front panel ports

• System health indicators and internal temperature control

We simulate real-world testing environments using calibrated optical sources and tunable lasers to ensure accurate diagnosis.

Common 86146B Problems We Resolve

• No optical signal detected or poor sensitivity

• Inaccurate wavelength measurements or signal instability

• Laser source not emitting or failing power-up self-test

• Damaged input connectors or internal fiber path misalignment

• Firmware errors, boot loops, or frozen display

• Broken display screens or control knobs

• Fan noise or power supply fluctuations

• Misaligned monochromator or grating issues

Board-Level & Optical Repair
We repair down to the component level, including replacing damaged ICs, capacitors, logic controllers, and power modules. Optical assemblies are realigned and cleaned, restoring signal transmission and reducing internal losses.

Tunable Laser Diagnostics & Repair
If your 86146B includes a built-in tunable laser, we perform specialized testing to ensure:

• Output power is within spec

• Tuning range operates correctly

• Sweep speed and wavelength tracking are stable
  We replace laser modules or related driver components as needed.

Optical Path Realignment & Grating Adjustment
The internal monochromator, grating motor, and optical mirrors are recalibrated and aligned to restore the original measurement fidelity and ensure high SNR and wavelength resolution.

Firmware Refresh & Internal Self-Test
Post-repair, the system is run through Agilent’s internal diagnostics and updated with the latest supported firmware version for enhanced performance and bug fixes.

NIST-Traceable Calibration with Certificate
After all repairs, the 86146B is calibrated using NIST-traceable reference lasers and power meters:

• Wavelength calibration

• Power level validation

• Dynamic range testing

• Sweep speed and span accuracy
  You receive a full calibration report with before/after data and certification.
