The entire assembly can be housed in a small die cast box or a light-weight hand held probe assembly depending on your preferences. The 100pf capacitor should be capable of withstanding the highest dc voltage which is likely to be met. Download scientific diagram | A schematic diagram of an active probe frequency extender. Efficient matching avoids reflection which in turn leads to efficient power transfer. Jul 15, 2025 ยท In this article I have explained a couple of very easy to build RF detector circuits, which can be used to sense or detect or sorts of Rf electrical noise this rf probe circuit allows rf to be measured in the presence of dc. An RF probe is a circuit designed for testing equipment that converts high-frequency signals into DC voltage. In such systems, like many other RF circuits, there is a higher requirement of matching probe impedance with that of the DUT. An RF probes are used to measure RF signals in an electronic circuit. The probe should give the same reading when the leads are reversed. - A 10x probe is meant to isolate the circuit from the scope as much as posible (using pasive probes), but the problem is the impedance mismatch (a 50 ohm termination at the scope input is not enough).
