WebSep 24, 2024 · In this way, an active probe with ±2.5-V dynamic range can read zero to 5 Vdc. Of course, differential probes are also active devices because they contain semiconductors, but the overall design, configuration with respect to the oscilloscope and ultimate purpose are entirely different. Differential Probes and accessories. WebWith passive filters, there is a contactor that is controlled by the variable frequency drive to turn on and off the filter to prevent a leading power factor condition. You have 2 devices but as far as function goes, a variable frequency drive preforms work and a filter preforms harmonic mitigation. As far as who to blame is simple.
