- The Zurich Instruments UHFLI is a digital lock-in amplifier covering the frequency range from DC to 600 MHz. In addition of providing the highest operation frequency amongst all commercial lock-in amplifiers, the UHFLI also offers the lowest time constant of 30 ns for demodulation, resulting in a demodulation bandwidth of more than 5 MHz. The exquisite analog front end offers a spectacular noise performance of 4 nV/√Hz which helps in many applications to keep the signal-to-noise ratios high while speeding up the measurement. In combination with the most innovative 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.
