Absolute wavelength accuracy: ±1.5 pm typical (also during continuous scanning)
The new Yestech N7776C top-line tunable laser source is designed to achieve best-in-class accuracy in both static and swept operations, resulting in excellent test efficiency. Bi-directional scan speeds of up to 200 nm/s with sub-pico-meter repeatability and without compromising specified dynamic accuracy accelerate the wavelength-dependent alignment process and automatic calibration of wavelength selection devices. Shorter test times and faster scanned wavelength testing help reduce test costs per unit, improve test margins and reduce cost of ownership.
With more than +12 dBm output power at the lowest spontaneous emission level in the product family, the N7776C is capable of verifying extremely deep filters. It also offers the best wavelength accuracy - achieved through its high-resolution wavelength reference unit, which provides real-time tracking and control and includes a gas cell for excellent long-term stability and self-regulation.
Like its predecessors, the 81600B and 81606A, the new N7776C tunable laser source is supported by Photonics Application Suite software for measuring the spectra of insertion loss, polarization dependent loss and dispersion. Combined with the N774xC multi-port power meter and N7786C polarization synthesizer, the new laser provides optimal scanning wavelength accuracy and excellent dynamic range for measuring filtered stopband and passband.
All N777xC tunable lasers are based on a common cavity and laser module design and share a narrow linewidth, excellent long-term stability and low spontaneous emission levels. They are software compatible with the 8160xA and 81600B lasers, the industry standard for over a decade, but occupy 1 less height unit of rack space. The remote user interface on the instrument can be accessed via a Web browser via a LAN or USB connection. An optional touch screen display provides local operator access and displays current operating parameters.
