Summary
Description
The Zurich Instruments UHFLI is a completely digital
lock-in amplifier with 1.8 GSa/s sampling rate at its signal inputs and signal generators. It operates in the frequency range up to 600 MHz, features the lowest time
constant in the market and consequently provides
unmatched performance for the most demanding applications.
High-precision Inputs
The UHFLI combines 2 lock-in amplifiers, 2 signal generators, 1 oscilloscope, 1 frequency response analyzer and
a powerful FFT spectrum analyzer in 1 box. Moreover, the
instrument also supports sweeping of several internal
parameters. This unprecedented integration is capable
of replacing a full set of instruments, thus simplifying
ever more complex instrumentation setups.
With the increasing requirements of research applications, the UHFLI has the capability to become the most
desired multi-functional instrument in any research laboratory. The wide frequency range, the ultra-wide demodulation bandwidth and the best-in-class dynamic
reserve make this instrument a new standard in the test
and measurement market.
Zurich Instruments equips all its instruments with
extended platform programmability: virtually any programming language can be used for remote control,
including LabVIEW, MATLAB, C, and Python. Linux and
any Windows version later than XP are supported.
Operating in single ended mode, the 2 signal inputs of the
UHFLI provide excellent noise specifications. It is possible to work with high impedance for low frequency and
with 50 Ω impedance for high-speed applications. 2 input
and 2 bidirectional connectors enable the external reference mode and precise triggering on external events.
Dual internal and dual-auto reference modes are also
supported.
Signal Generators
The UHFLI generates 2 low-distortion sinusoid outputs
ideally capable to drive the device under test or most
modulating devices. With the UHF-MF multi-frequency
option 6 additional oscillators are provided, and it is possible to generate a linear combination of up to 8 independent sinusoids.
Additional connectors on the front panel carry demodulated samples, square wave references or signal to trigger external hardware.
Demodulators and Filters
Eight dual-phase demodulators for simultaneous measurement at 4 harmonic frequencies per signal input are
provided. Each demodulator can be configured with its
own filter properties and phase shift and demodulated
samples are streamed in real-time to the host computer.
