Introduction
The Zurich Instruments HF2LI is a digital lock-in amplifier covering the frequency range between DC and 50 MHz. It is the instrument of choice for the characterization of MEMS devices such as gyroscopes and for measurements in the area of microfluidics. The HF2LI is equipped with the Zurich Instruments control software LabOne, which provides a web-based user interface featuring a spectrum analyzer, a sweeper and a basic oscilloscope, among others. A number of upgrade options can extend the functionality of the HF2LI to adapt to different applications. Furthermore, combining the HF2LI with the HF2TA Current Amplifier enables direct current readout.
