📘 Introduction: What is the Agilent / HP 86142B?

Originally developed by Hewlett-Packard (HP) and later supported by Agilent Technologies and Keysight, the 86142B is a high-performance benchtop optical spectrum analyzer that delivers high dynamic range, superior wavelength resolution, and flexible automation features.

🔍 Key Specifications:

The 86142B is a workhorse—whether you’re validating DWDM systems or analyzing tunable laser modules, this OSA delivers stable, accurate, and repeatable measurements for years.

🧰 Common Use Cases of Agilent 86142B

At Aumictech, we work with clients across North America and internationally who use the 86142B for critical tasks such as:

✅ Dense Wavelength Division Multiplexing (DWDM) Testing:

• Verifying channel wavelengths and spacing
• OSNR (Optical Signal-to-Noise Ratio) measurement
• Adjacent channel suppression evaluation

✅ Passive Component Testing:

• Insertion loss and passband testing of WDMs, optical filters, isolators, splitters, and couplers

✅ Laser Source Characterization:

• DFB, tunable, and multi-wavelength laser analysis
• Spectral purity, ASE noise testing

✅ Telecom Lab Automation:

• GPIB-based automated test sequences
• Factory-floor integration in photonic component production

With high measurement repeatability and stability, the 86142B remains a go-to OSA for long-term applications in photonics and optical communications.

❌ Common Failures in the 86142B – What Can Go Wrong?

As robust as it is, the Agilent 86142B can develop faults over time, especially in harsh industrial environments. Here are the top issues we see and fix at Aumictech:

🔧 Hardware Failures:

• Internal detector alignment issues
• Damaged grating wheel or stepper motor
• Failing optical input ferrule or connector wear
• Laser reference source degradation

🔧 System Errors:

• Unit stuck at boot screen
• No display or corrupted VGA output
• GPIB interface malfunction or RS-232 failure
• Intermittent sweep halts or measurement freezes

🔧 Environmental Damage:

• Dust contamination in optical path
• Power supply board burnout due to voltage spikes
• Internal cooling fan failure and thermal alarms

We can rebuild or replace damaged parts, align internal optics, clean and polish connectors, and restore firmware to stabilize your system.

🧪 Full-Service NIST-Traceable Calibration for 86142B

Precision is critical in telecom and optical testing environments. That’s why Aumictech offers full, NIST-traceable calibration services for Agilent 86142B OSAs, meeting stringent ISO and industry standards.

✔️ Calibration Includes:

• Wavelength accuracy testing using certified reference sources
• Resolution bandwidth verification across all RBW settings
• Dynamic range calibration using optical attenuators
• Power level correction at various input levels
• Sweep timing and refresh rate optimization

You’ll receive a calibration certificate with traceable standards, before-and-after performance data, and recommendations for the next service cycle.

🔁 86142B vs. Other OSA Models – Why Keep It in Use?

The 86142B is repairable, reliable, and still widely in use, with many available parts and trained service technicians (like us at Aumictech!). It’s an ideal candidate for refurbishment, calibration, and continued use instead of replacing with costly new models.
