With the GHFLI and SHFLI Lock-in Amplifiers, modern signal production, control, and analysis are now possible with microwaves.
By combining lock-in amplifiers’ high noise rejection and measurement speed with a full microwave measurement suite, including an Oscilloscope, a Spectrum Analyzer, a Parametric Sweeper, and more, these amplifiers simplify complex problems for scientists and engineers.
Highlights
Zurich Instruments’ new GHFLI and SHFLI bring together – for the first time in the GHz range – the measurement speed and high noise rejection of lock-in amplifiers. They combine this with a full microwave measurement suite that includes an Oscilloscope, a Spectrum Analyzer, a Parametric Sweeper, and more, reducing complexity for Scientists and Engineers.
Description
The GHFLI and SHFLI can handle a wide variety of experimental conditions thanks to their two independent channels, each of which can measure multiple signals in parallel and generate multi-tone waveforms.
The intuitive user interface allows all the measurement tools to be run in parallel, providing an overview of the signals at a glance. Their demodulator filters provide the freedom to find the best tradeoff between noise rejection and measurement speed in every situation.
The high-data-rate digital interfaces to the computer enable simple data acquisition while, at the same time, the 8 auxiliary outputs can convert the results into analog signals for integration with other instrumentation or to provide feedback. Both instruments can operate down to DC, and the GHFLI measures up to 1.8 GHz while the SHFLI up to 8.5 GHz.
Application
The GHFLI and SHFLI are ideal choices when it comes to measuring periodic signals quickly and reliably, benefiting a broad range of applications from DC to microwaves, including NEMS device control, spin qubit characterization, ultrafast laser spectroscopy, surface acoustic waves, and spintronics.
