This new video discusses the unique measurement capabilities of our M81-SSM, a complete transport characterization system that integrates DC + AC sourcing and measuring — including lock-in detection capabilities — for ultra-low noise, highly sensitive measurements.
In the hands-on video, we look at the system’s components, including four types of amplifier modules that are combined with the M81-SSM instrument to enable low-level DC, AC, and mixed AC/DC measurements. We specifically discuss how all source and measure channels are simultaneously sampled at a very high rate and provide DC to 100-kHz operation, including lock-in operation, on up to 3 source and 3 measure channels at the same time to ensure time-correlated synchronous measurements.
Also demonstrated is how quickly and easily the M81-SSM can measure various values of resistance using very low DC and AC currents, illustrating the limitations of DC methods and the advantages of AC lock-in methods as the signal of interest becomes affected by thermal offsets and other parasitic effects.
