Here you'll find attached the presentation files showed during the Seminar held at IBEC last 23rd of May.
In this seminar, we showed several Software Defined lock-in amplifier configurations and applications with several inputs.
The Seminar is divided in 2 blocks: NI LabVIEW introduction and Lock-In Amplifier Theory and applications.
The Introduction to LabVIEW will give a basic understanding of how a VI works:
• How a LabVIEW program or Virtual Instrument (VI) works.
• Basic structures of programming: Loops, Boolean Logic, Case Structures
• Building a user interface
• Real world applications in microscopy facilities.
During the Lock-In section some concepts on signal processing will be introduced (Sampling theory, Frequency and Time representations, Fourier Transform and Noise in measurements) and will mainly focus on a real application using a Lock-In Amplifier to characterize a system that simulates the behavior of Biological samples.
