This unit
The Keysight 86120C is a Michelson interferometer-based multi-wavelength meter that simultaneously measures wavelength and optical power across multiple laser lines. Operating from 1270 nm to 1650 nm (182 to 236 THz), it handles up to 200 laser lines with ±2 ppm absolute wavelength accuracy (±0.003 nm at 1550 nm and 1310 nm) for lines separated by ≥15 GHz. Measurement cycle time is less than 1 second.
The instrument features a built-in HeNe laser wavelength standard, graphical optical power spectrum display, and state save/recall capability. Maximum safe input power is +10 dBm. Equipped with SCPI programming support and front-panel optical connectivity, the 86120C serves applications in DWDM signal testing, Fabry-Perot laser characterization, and optical component verification across development, manufacturing, and field installation environments.

Compatibility & Integration The 86120C is a legacy product; the Keysight 86120D provides current-generation functionality.
Agilent / Keysight 86120C — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 86120C. Calibration covers absolute wavelength accuracy at multiple reference points across the full measurement range, frequency accuracy, wavenumber accuracy, and multi-wavelength channel spacing measurement accuracy. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 86120C faults: interferometer alignment drift, reference etalon or HeNe laser end-of-life, InGaAs detector sensitivity loss, fiber input connector damage. Fizeau interferometer-based instruments (Agilent 86120B/86122A/C) most commonly develop interferometer alignment drift and InGaAs detector degradation over time. Burleigh WA-series scanning Fabry-Perot instruments most commonly fail due to reference HeNe laser end-of-life. Both types are fully repairable with post-repair wavelength accuracy verification.
