Phase-locked loop frequency multiplier and divider use cases
Introduction The digital phase-locked loop (PLL) is a powerful technique used in Moku devices to continuously track the phase of an input signal with zero dead time. This technique is used in Moku’s Lock-in Amplifier and Laser Lock Box to generate a phase-locked demodulation signal, and in the Phasemeter to measure the real-time phase, frequency,…

SRS microscopy experiments with Moku:Pro at the University of Washington
Contributed by Brian Wong and Dan Fu, Department of Chemistry, University of Washington Summary Moku:Pro’s Lock-in Amplifier (LIA) provides an intuitive, precise, and robust solution for self-heterodyne signal detection in Stimulated Raman Scattering (SRS) microscopy experiments. A quality LIA is a critical hardware component in SRS microscopy experiments with a modulation transfer detection scheme. In…

Phase Detection with Lock-in Amplifier and Phasemeter
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…
