Agilent / Keysight 81608A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 81608A. Calibration covers wavelength accuracy at 5 or more points across the full tuning range, mode-hop-free range, output power flatness, linewidth, and side-mode suppression ratio (SMSR). All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 81608A faults: output power drift, mode hops, fiber pigtail connector damage, wavelength inaccuracy. Common faults include output power drift after extended use, mode hops at specific wavelengths, and fiber pigtail connector damage. Full alignment and piezo calibration typically restore performance to spec.
