The Keysight N7776C tunable laser source with option 113 has the following characteristics2:
- High Power Output: It can reach a maximum peak power of > +13 dBm, which is beneficial for applications requiring high - power laser sources, such as validating extremely deep filters.
- Wide Wavelength Range: It supports wavelength tuning in the ranges of 1240 - 1380 nm, 1340 - 1495 nm, 1450 - 1650 nm, or 1490 - 1640 nm, providing flexibility for different optical measurement and testing scenarios.
- Fast Sweep Speeds: The bidirectional sweep speed can be up to 200 nm / s, enabling efficient wavelength - dependent alignment processes and the automated calibration of wavelength - selective devices. This helps reduce test time and cost per device.
- High Signal - to - SSE Ratio: The typical signal - to - SSE ratio is ≥ 80 dB / nm, which means it has low spontaneous emission and can provide a clean and stable laser output for accurate measurements.
- Excellent Wavelength Accuracy: The absolute wavelength accuracy is ± 1.5 pm typical, even during continuous sweeps. This is enabled by its high - resolution wavelength reference unit that includes a gas cell for excellent long - term stability and self - adjustment capability.
- Enhanced Wavelength Tuning Performance: The default fine - tuning is enhanced without overshoot. Automatic coordination of the motor and piezoelectric - actuator allows for smooth tuning with 0.1 pm resolution, simplifying wavelength - optimization procedures.
- Software Compatibility: Like its predecessors 81600B and 81606A, it is supported by the photonic application suite software for spectral measurements of insertion loss, polarization - dependent loss, and dispersion. It can also work with the N774xC multiport power meters and the N7786C polarization synthesizer to provide optimal swept - wavelength accuracy and an excellent dynamic range for measuring filter stop bands and pass bands.
- Compact Design: All N777xC tunable lasers are based on a common cavity and laser module design. They are software - compatible with the 8160xA and 81600B lasers, occupying 1 height unit less rack space.
- Convenient User Interface: The remote user interface on the instrument is accessible with just a web browser, either via LAN or via USB connection. An optional touch - screen display provides local operator access and displays current operating parameters.
