N7776C High Power and Lowest SSE
The new Keysight N7776C top line tunable laser source is designed to reach best-in-class accuracy and sub-picometer repeatability in static and swept operation for outstanding test efficiency. With the product family’s lowest spontaneous emission level, the N7776C enables the validation of extremely deep filters. It also offers the best wavelength accuracy in the family – enabled by its high-resolution wavelength reference unit that provides real-time tracking and control and includes a gas cell for excellent long-term stability and self-adjustment capability. Shorter time to testing and faster swept-wavelength tests help reduce test cost per device, improve test margins and lower the cost of ownership. With more than +12 dBm output power, the N7776C enables the validation of extremely deep filters.

N7778C High Power and Low SSE
The N7778C value line tunable laser source offers a peak output power of more than +12 dBm, at least 75 dB/nm above its spontaneous emission level. It features a typical wavelength repeatability of ±1.5 pm at two-way sweeps up to 200 nm/s. The N7778C’s balance of features, performance, and price makes it suitable for cost-effective, high-throughput manufacturing-floor component testing as well as for coherent transmission experiments.
The N7778C’s wavelength tuning performance is enhanced to provide default fine-tuning without overshoot. No separate fine-tuning control is needed for smooth tuning with 0.1 pm resolution due to the automatic coordination of the motor and piezoelectric actuator. This simplifies wavelength-optimization procedures.

N7779C High Power and Low SSE / Stepped Tuning
The new N7779C basic line tunable laser source, like the other new N777xC models, can step quickly to discrete wavelengths with a resolution of 0.1 pm and a typical wavelength repeatability of ±3 pm, making it ideal for cost-effective testing of broadband optical devices. With wavelength setting times like 300 ms, rapid stepped sweeps are possible. Like the other lasers in the N777xC family, it delivers more than +12 dBm peak output power with low spontaneous emission levels. At ±0.01 dB power stability over an hour, it can also serve as a static local oscillator with a wide tuning range for receiver testing or transmission experiments.
