HP Agilent 81642A Tunable Light Source TLS Repair and Calibration Services
Simbol Test Systems Inc. provides professional HP Agilent 81642A Tunable Light Source repair and calibration services for customers who require reliable performance from legacy optical test equipment. Simbol specializes in the repair of tunable laser sources (TLS), optical spectrum analyzers (OSA), and wavelength meters, with extensive experience servicing discontinued Agilent and HP platforms.
The HP Agilent 81642A Tunable Laser Source has been discontinued for many years, but it remains a strong candidate for repair in many cases. This model is similar to the 81640A, with a High Output port and no Low SSE port. Over the years, Simbol has developed solid expertise in 81642A service and can address issues related to PCB assemblies, optical block, motor, initialization errors, and self-test error messages. We have had a high success rate with 81640A and 81642A TLS units, particularly when the original Agilent seals remain intact.
All calibration services are performed in our laboratory using documented procedures, traceable standards, and experienced technical staff. 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). Following service, your equipment may be returned with a calibration label, calibration certificate, and related calibration data.
Because alarm messages shown on the display do not always identify the actual fault, we recommend sending us an email with your model number and a brief description of the issue. We can review the reported problem, provide feedback on likely repairability, and issue an RMA with an estimated turnaround time. If you are considering replacement instead of repair, you can also browse available tunable laser source inventory through AssetRelay.
