Jelena Trbovic (jelena.trbovic@zhinst.com)
In this webinar, Jelena and Prof. Martino Poggio (University of Basel) look into how macroscopic manifestations of quantum mechanics involving strongly correlated states, e.g. superconductivity and magnetism, are sensitive to the local environment. Nanometer-scale spatial resolution is often required to identify the conditions for the emergence of such macroscopic behaviors. Martino talks about the basic principles and applications of magnetic imaging techniques, including NV-center and nano-wire MFM microscopy, that shed light on magnetization patterns, spin configurations and current distributions. Jelena shows how lock-in amplifiers can be used with such local probing techniques to enhance their sensitivity and contrast. In this blog post, Jelena answers the questions asked during the live session.

Claudius Riek (claudius.riek@zhinst.com)
In this webinar, Claudius shows how specific settings on lock-in amplifiers and boxcar averagers impact the results of a measurement in optical experiments by looking at the filter function, the filter order and the time constant. He then discusses the relevance of typical properties of electronic measurement devices for optical experiments such as the instrument's dynamic range, measurement bandwidth and signal input noise. Claudius answers the questions asked during the live session in this blog post.

Mehdi Alem (mehdi.alem@zhinst.com)
In this webinar, Romain and Mehdi discuss how to address complex detection schemes in scanning probe microscopy (SPM) with the highest possible resolution. They carry out tutorials on Kelvin probe force microscopy (KPFM) and electrical pump-probe methods, and consider a practical example of FM-KPFM measurement using the MFLI Lock-in Amplifier with a FlexAFM microscope. Romain's blog post highlights some important take-home messages, includes useful additional resources, and summarises the answers to the many questions asked during the live event.

Romain Stomp (romain.stomp@zhinst.com)
In this webinar, Claudius and Romain are joined by Prof. Markus Raschke (University of Colorado Boulder) and his student Mr. Samuel Johnson to present the growing field of tip-enhanced scanning probe microscopy and its application to precision spectroscopy, ultrafast-nano-imaging and, in the strong coupling limit, cavity quantum electrodynamics. In particular, Claudius shows how to maximize the signal and image information content with advanced measurement instrumentation.

Claudius Riek (claudius.riek@zhinst.com)
In this webinar, Claudius focusses on four prototypical techniques in optics and photonics: tunable diode laser absorption spectroscopy (TDLAS), pump-probe spectroscopy, stimulated Raman scattering (SRS), and carrier-envelope offset (CEO) stabilization. He looks into how to choose the most suitable measurement scheme for your experiment, e.g. a lock-in amplifier or a boxcar averager, and discusses how to save precious measurement time and record high-quality data with the highest signal-to-noise ratio. Claudius answers the questions asked during the live session here; he covers some crucial aspects related to the topic of his webinar in this blog post.

Tim Ashworth (tim.ashworth@zhinst.com)
In this webinar, Tim looks at two impedance measurement challenges. In the first case, he shows how to measure equivalent series resistance (ESR) below 1 mOhm and equivalent series inductance (ESL) below 20 nH for a DC-Link capacitor. In the second example, he discusses how to strike a balance between measurement speed and precision in fast capacitance measurements (on the time scale of microseconds) used to investigate the transient behavior of devices and materials. Tim's answers to many of the questions asked during the live session are available here.
