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. Thanks to the combination of a wide choice of available options and the instrument control software LabOne, the UHFLI is an excellent choice for your experimental needs.
