产品详情

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.

UHFLI Available Options


UHF-DIG Digitizer


The combination of Lock-in amplifier and Digitizer in one box enables a wide range of new measurement opportunities utilizing continuous streaming, sophisticated cross-domain triggering and a segmented 128 MSa memory for each of the 2 Scope channels.


UHF-MF Multi-frequency


The UHF-MF Multi-frequency option adds another 6 internal oscillators to the instrument and allows a free choice of frequency for every of the 8 demodulators. This extends the capability of the UHF Instrument tremendously by offering a wide range of additional configurations for measurement and signal generation.


UHF-MOD AM/FM Modulation


The AM/FM modulation option allows to generate phase-coherent linear combinations of up to 3 oscillator frequencies. The direct measurement of (higher-order) sidebands in a variety of different modulation schemes, including amplitude modulation (AM) and frequency modulation (FM), can be conveniently set up. Unlike conventional double demodulation schemes, e.g. tandem demodulation, the user will not need multiple instruments and is also not limited in modulation frequencies by the maximum available demodulation bandwidth.


UHF-PID Quad PID/PLL Controller


The UHF-PID option consists of 4 configurable PID (proportional - integral - derivative) controllers. Based on a variety of different measurement data they can provide fast feedback to a number of instrument parameters and output values. Seamlessly integrated with the lock-in amplifier, the programmable PIDs enable operation in a wide range of applications such as the setup of PLLs (phase-locked loops) for phase synchronization of two lasers, CEO stabilization and fast AFM modes.


UHF-BOX Boxcar Averager


The UHF-BOX Boxcar Averager is the first fully digital boxcar averager in history opening new perspectives and innovative ways of analyzing non-sinusodial signals with low duty cycles. It operates as a high speed digitizer synchronized to an oscillator and therefore captures every sample without any dead times while rejecting all non-periodic signal components.


UHF-RUB Rubidium Atomic Clock


The UHF-RUB upgrade option provides an atomic frequency standard to the UHFLI instrument. Experiments in need of a high frequency accuracy and stable operation over long periods of time even in adverse conditions, e.g. laboratories with limited climate-control, can rely on the Rubidium based atomic clock. Moreover, calibration demands are also further reduced as there is essentially no clock aging. The UHF-RUB is a hardware option that cannot be upgraded later in the field.


UHF Boxcar


The UHF Boxcar is a bundle containing the UHFLI 600 MHz lock-in amplifier and the UHF-BOX Boxcar upgrade option.


UHF Digitizer


The UHF Digitizer is a bundle containing the UHFLI 600 MHz lock-in amplifier and the UHF-DIG Digitizer upgrade option.

The combination of Lock-in amplifier and Digitizer in one box along with the LabOne® toolset enables a wide range of new measurement opportunities utilizing continuous streaming, sophisticated cross-domain triggering and a segmented 128 MSa memory for each of the 2 Scope channels.


UHF-AWG Arbitrary Waveform Generator


The UHF-AWG option brings state-of-the-art Arbitrary Waveform Generator (AWG) capabilities to the UHFLI, the world's fastest and most advanced lock-in amplifier. The result is a very powerful combination of complex signal generation and analysis tools conveniently orchestrated through LabOne®, the intuitive and platform-independent instrument control software.


UHF-CNT Pulse Counter


The UHF-CNT Pulse Counter features analysis of up to 4 pulse trains in parallel, enabling event based measurements, e.g. photon detection using photo-multiplier tubes. There are five distinct modes of operation and each channel offers an adjustable discriminator. The maximum count rate is 225 MHz. Measurement results from the pulse counters can be conveniently analyzed with the LabOne® toolset, which features time domain and histogram display.
