Agilent 86120A Wavelength Meter Calibration and Repair Services
Simbol Test Systems Inc. provides professional Agilent HP 86120A Wavelength Meter calibration and repair services for customers who require accurate, reliable performance from their optical test equipment. All calibration services are performed in our laboratory using documented procedures, traceable standards, and experienced technical staff.
We have experience servicing the Agilent HP 86120A Wavelength Meter, including troubleshooting and repair of common faults such as E14, E7, and E4 errors. Our service process is designed to verify instrument performance in accordance with generally available manufacturer specifications and internal technical procedures.
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. If the unit does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding.
Contact us with your model number and a brief description of the issue to request a calibration quote or repair evaluation for your Agilent HP 86120A Wavelength Meter.

The Agilent / HP 86120A Wavelength Meter is a highly precise optical instrument, but age, mechanical wear, and internal laser drift can lead to measurement errors and system faults. One of the most common issues is Error E14, indicating that the internal reference laser is no longer operating within specification. Another frequently encountered fault is Error E7 – Motor Not Settled, which occurs when the wavelength meter cannot properly control the internal motor responsible for mirror positioning.
Our laboratory specializes in the complete repair, calibration, and refurbishment of the 86120A series. Whether your unit requires a motor repair, motor replacement, laser restoration, or a full diagnostic evaluation, our technicians ensure your instrument is restored to original performance standards.
✔ Complete Repair, Calibration & Refurbishment
When you send your Agilent 86120A to our service center, we perform a full evaluation of the optical, mechanical, and electronic subsystems. After repair, your wavelength meter is returned fully calibrated with complete calibration data. Our optional full refurbishment process includes extended testing, component replacement, and a one‑year warranty on the entire unit—not just the laser.
✔ Common 86120A Issues We Repair
- Internal reference laser failure (E14)
- Motor control and positioning errors (E7)
- Optical alignment drift
- ROM, NVSRAM, and calibration data faults
- Power level, gain, and signal detection errors
- Initialization and hardware communication failures
