Service & Repair of HP 70952B Optical Spectrum Analyzer OSA

HP 70952B Optical Spectrum Analyzer – Expert Repair, Modular Restoration & NIST-Traceable Calibration

We provide comprehensive repair, calibration, and refurbishment services for the HP 70952B Optical Spectrum Analyzer, a high-performance module in the HP 70000 Modular Measurement System. Designed for precision optical signal analysis in telecom, fiber optic, and photonics applications, the 70952B is known for its extended wavelength range and high dynamic performance. Whether your module is experiencing optical signal loss, system errors, or failing to initialize, our team of experienced technicians can restore it to peak performance with NIST-traceable calibration and factory-grade diagnostics.


Full Repair & Calibration Process

Thorough Diagnostic Testing
Each HP 70952B unit is installed in a functioning HP 70000 Series mainframe for detailed system testing, including:

  • Wavelength accuracy and spectral resolution

  • Optical signal detection and trace repeatability

  • Span, sweep time, and noise floor performance

  • Power measurement linearity and stability

  • Input port condition and optical alignment

  • Front-panel softkey response and display (if applicable)

  • GPIB and system bus communication

We simulate real-world test conditions using tunable laser sources and calibrated optical references to identify signal loss, drift, or electronics failure.

Typical Issues We Repair

  • No signal detection or poor sensitivity

  • Wavelength inaccuracy or measurement drift

  • Module not initializing or not recognized by the mainframe

  • Internal photodetector failure or alignment shift

  • Sweep malfunction or frozen trace

  • Damaged or misaligned fiber optic input connector

  • Power supply issues or noisy voltage rails

  • Signal processing or A/D board errors

  • GPIB communication failure or firmware corruption

Electronics & Component-Level Repair
We perform detailed board-level repair, including:

  • Replacement of failing capacitors, op-amps, regulators, and logic ICs

  • Repair of analog and digital signal paths

  • Troubleshooting module-to-mainframe communication errors

  • Reconditioning or replacement of faulty power circuits

Optical Cleaning & Alignment
The internal optical path is inspected and restored for clarity and performance. This includes:

  • Cleaning fiber couplers, lenses, and mirrors

  • Realignment of beam paths for accurate signal detection

  • Repair or replacement of worn FC/APC or SC connectors

Mainframe Compatibility & Firmware Verification
We verify full operation inside an HP 70000 Series mainframe, ensuring proper boot sequence, trace functionality, and remote communication via GPIB or system interface.

NIST-Traceable Calibration
Each unit is calibrated using NIST-traceable reference lasers and power meters, including:

  • Wavelength accuracy verification

  • Power level linearity and trace response

  • Sweep and span testing

  • Resolution bandwidth and dynamic range checks
    A calibration certificate with before-and-after results is provided.
