UHFLI 600 MHz Lock-in Amplifier

The UHFLI 600 MHz Lock-in Amplifier from Zurich Instruments dual-channel lock-in amplifier, designed to operate at frequencies from DC up to 600MHz.

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.

In combination with the widest choice of available options and the instrument control software LabOne, the UHFLI is the flagship of all Zurich Instruments products and represents the state of the art of today’s scientific instrumentation.
