HF2PLL Phase-Locked Loop
Summary
Zurich Instruments' HF2PLL (high-frequency, dual phase-locked loop) combines a dual digital lock-in amplifier covering the frequency range between 0.7 μHz and 50 MHz in combination with 2 high-frequency PLLs. There are 2 physical input channels and 2 high-frequency signal generators which will enable the replacement of 2 conventional instruments in most laboratory setups. The 128-bit digital signal processing delivers superior precision thus improving both the noise performance and the dynamic reserve. With these unprecedented capabilities, the HF2PLL provides a new level in state-of-the-art phase sensitive measurements and enables new applications in the high-frequency range.
This non-standalone instrument relies on the host computer for the graphical user interface. This architectural choice provides unprecedented software integration with LabVIEW, MATLAB, C, and almost every other programming language. This way of working is suitable for both beginners and advanced users. In addition, the software permits an unlimited number of clients to access the HF2PLL at the same time, ideal for complex applications.
The PLLs provide fully configurable support for accurate frequency tracking, while the lock-in amplifiers provide best-in-class signal recovery featuring the Zurich Instruments unique 128 bit technology.
The HF2PLL is a bundle of the HF2LI lock-in amplifier and the HF2LI-PLL option.
