This unit
The Keysight N7778C Step-Tunable Laser Source is a ECL tunable laser engineered for optical testing, manufacturing, and research applications. It delivers narrow linewidth operation below 10 kHz with excellent long-term wavelength stability and suppressed spontaneous emission, enabling precise spectral measurements and high-throughput device characterization. The instrument combines cost-effective operation with the tuning speed and accuracy demanded by modern optical component testing, while maintaining software compatibility with industry-standard 8160xA and 81600B platforms.

Agilent / Keysight N7778C — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight N7778C. 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 N7778C 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.
