GHFLI 1.8 GHz Lock-in Amplifier

GHFLI Lock-in Amplifier

The GHFLI Lock-in amplifier from Zurich Instruments 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.

SHFLI 8.5 GHz Lock-in Amplifier

SHFLI - Lock-in Amplifier

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.

HF2LI 50 MHz Lock-in Amplifier

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.

UHFLI 600 MHz Lock-in Amplifier

The Zurich Instruments UHFLI is a digital lock-in amplifier that covers the frequency range from DC to 600 MHz. In addition to providing the highest operation frequency among all commercial lock-in amplifiers, the UHFLI offers the lowest time constant of 30 ns for demodulation – resulting in a demodulation bandwidth that exceeds 5 MHz.

MFLI 500 kHz / 5 MHz Lock-in Amplifier

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.
