Microwave Lock-in Amplifiers

Zurich Instruments’ new GHFLI and SHFLI Lock-in Amplifiers are the trailblazers that bring state-of-the-art signal generation, analysis, and control to microwaves. They combine the measurement speed and high noise rejection of lock-in amplifiers with a full microwave measurement suite that includes an Oscilloscope, a Spectrum Analyzer, a Parametric Sweeper, and more, reducing complexity for scientists and engineers.

Trailblazers. The GHFLI and SHFLI Microwave Lock-in Amplifiers.

Feedback at Microwave Frequencies

The Quad PID/PLL option unlocks the precise and fast closed-loop feedback at GHz frequencies. With one instrument, you can stabilize your resonators or circuits and track their behavior from DC to 8.5 GHz.

Adding the Quad PID/PLL option to the GHFLI and SHFLI Lock-in Amplifiers enables a comprehensive set of input- and control-signal choices. Multiple controllers that can run in series or parallel enable your required feedback mode.  

The LabOne User Interface offers intuitive visualization and control of your experiment, reducing complexity and time to publication.

Sideband Analysis and Heterodyne Measurement Schemes

Unlock new capabilities for your GHFLI and SHFLI Lock-in Amplifiers with the MOD option. This upgrade seamlessly integrates sideband analysis and heterodyne schemes with lock-in detection.

With the power of phase-sensitive lock-in detection, the new option facilitates phase-coherent analysis of modulated signals at both sideband and carrier frequencies. It empowers users to generate sideband frequencies and drive various analog modulation schemes within the GHz frequency range, including amplitude modulation (AM) and frequency modulation (FM).

Moreover, it unlocks the potential for frequency mixing beyond typical modulation schemes, paving the way for the implementation of heterodyne and parametric schemes.
