Introduction
This powerful product integrates two 50 MHz phase-locked loops (PLLs) with two independent 50 MHz lock-in amplifiers. The PLLs offer fully configurable support for accurate frequency tracking, whereas the lock-in amplifiers provide best-in-class signal recovery.

The HF2PLL Phased-Locked Loop is a bundle consisting of the following products:

• HF2LI Lock-in Amplifier
• HF2LI-PLL option
• HF2LI-PID option

Applications

• Atomic force microscopy (AFM)
• Scanning tunneling microscopy (STM)
• Near-field scanning optical microscopy (SNOM, NSOM)
• Micro-electromechanical systems (MEMS)
• Resonators and magnetometers
• Frequency combs: time reference definition
• Semiconductor characterization and testing
