Lock-In Amplifiers

The Zurich Instruments MFLI is a digital lock-in amplifier that covers the frequency range from DC to 500 kHz (and up to 5 MHz when upgraded). Thanks to its embedded data and web servers, the MFLI can be used directly with any device running a web browser without further software installations.

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 characterisation 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 analyser, a sweeper and a basic oscilloscope, among others.

The Zurich Instruments UHFLI is a digital lock-in amplifier that covers the frequency range from DC to 600 MHz. It offers a time constant of 30 ns for demodulation – resulting in a demodulation bandwidth that exceeds 5 MHz.

The Zurich Instruments GHFLI Lock-in Amplifier extends the advantages of lock-in amplifiers – noise rejection, phase sensitivity, frequency tracking and more – to applications that operate at frequencies up to 1.8 GHz.

The Zurich Instruments SHFLI Lock-in Amplifier brings the advantages of lock-in amplifiers – noise rejection, phase sensitivity, frequency tracking and more – to applications that operate at frequencies up to 8.5 GHz.
