Phase-locked loop (PLL) frequency synthesizer
50 MHz, 2 independent PLLs Zurich Instruments

The HF2PLL is a bundle of the HF2LI lock-in amplifier and the HF2LI-PLL option. Main feature include:
- 2 50 MHz phase-locked loops
- 2 independent fully configurable lock-in units
- 2 high-frequency, high-performance signal generators
- 50 kHz PLL bandwidth with full parameter control
- Q-Control, increase and decrease
- PLL Advisor for assisted loop parameter determination

It is a high-performance instrument combining two 50 MHz phase-locked loops with two independent 50 MHz lock-in amplifiers. 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. With 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.

Applications: atomic force microscopy (AFM), micro electro-mechanical system (MEMS, NEMS)
