HP Agilent 81642B Tunable Light Source TLS Repair and Calibration Services
Simbol Test Systems provides professional in-lab HP Agilent 81642B Tunable Light Source repair and calibration services to help maintain accurate, reliable performance for your optical test and measurement equipment. Simbol specializes in the repair of tunable laser sources (TLS), optical spectrum analyzers (OSA), and wavelength meters, with extensive experience servicing legacy Agilent and HP platforms.
The Agilent HP 81642B Tunable Laser Source has been discontinued for many years, but it remains a robust platform that is often worth repairing. Over the years, Simbol has developed solid expertise in 81642B repair. We have had a high success rate with 81642A and 81642B TLS units, particularly when the original Agilent seals remain intact. Because display alarm messages do not always identify the actual fault, we recommend sending us a brief description of the problem for an initial review.
Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the unit does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding. These units are often serviced at a fixed repair rate when applicable.
Traceability: Instrumentation used during this calibration is traceable to N.I.S.T. (National Institute of Standards and Technology) or C.N.R.C. (Canadian National Research Council).
Contact us with your model number and a brief description of the issue to request an RMA, calibration quote, or repair evaluation. If you need to replace the unit, you can also browse tunable laser inventory at AssetRelay.
HP Agilent 81642B Tunable Light Source (TLS) – Repair and Calibration Services
The HP / Agilent 81642B Tunable Light Source has been discontinued for many years, yet it remains one of the most reliable and widely used TLS units ever produced. These instruments are known for their stability and precision, making them highly valuable even today. Over time, however, aging components and internal wear can lead to wavelength drift, output instability, or complete failure.
Simbol has developed extensive expertise in repairing and restoring the 81642B—and its predecessor, the 81642A. With decades of experience, our technicians successfully revive over 95% of all 81642A/B units sent to us, provided the original Agilent seals are still intact.
Reliable, Fixed‑Rate Repair Services
Because the 81642B can fail in many different ways, it is extremely difficult to diagnose the required repair based solely on the alarm messages displayed on the screen. For this reason, Simbol offers fixed‑rate repair services for the 81642B, ensuring predictable costs and a streamlined process.
To begin, simply send us an email describing the issue. We will review your symptoms, provide initial feedback, and issue an RMA along with an estimated turnaround time. Simbol repairs at least one HP/Agilent TLS every month, making us one of the most experienced independent labs in North America for these instruments.
Comprehensive Post‑Repair Calibration
After repair, your 81642B Tunable Light Source will undergo a complete calibration to ensure it meets or exceeds OEM performance specifications. Your unit will be returned with:
- A calibration certificate
- A calibration label with date and due date
- Full calibration data for your records
When Replacement Is Necessary
Although most units can be repaired, some 81642B TLS modules may be beyond economical restoration due to severe internal damage. If your unit cannot be revived, Simbol will advise you and recommend suitable replacement options.
