    Introduction The Moku:Pro Frequency Response Analyzer (FRA) is designed to drive a device under test (DUT) with a swept sine wave and retrieve the amplitude and phase responses by a direct-conversion receiver. Before the 2.4.0 software update, the measured amplitude response could be represented as either the absolute amplitude in dBm or relative In÷Out amplitude…

    Precise and sensitive phase detections are often required for impedance and optics-based measurements. For example, measuring the phase shift between current and voltage reveals the complex impedance of a device or component. Very small displacements can be measured by the phase shift between control and measurement arms from an optical interferometer. Liquid Instruments’ Moku platform…

    Introduction At the University of Alberta, researchers are working to develop ultra-sensitive devices to improve dark matter detector technologies. This requires high-precision measurements, initially as a prototype in the lab and ultimately as an online monitoring system to be installed at 2km underground. Moku:Lab’s compact form factor and versatility enable researchers to perform experiments in…
