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. 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.
