2017年6月29日 · Choose a probe whose input resistance and capacitance match the input resistance and capacitance of your scope. Typically, it is desired for the probe to have the …

2021年5月3日 · Discover the importance of an oscilloscope probe: a device that connects a test point or signal source to an oscilloscope. Learn about the considerations and anatomy of a probe and how it can impact

An oscilloscope probe connects an oscilloscope to a device under test (DUT). Probes then transfer the signal from the DUT to the oscilloscope for analysis, enabling you to measure and …

In this article, I discuss the device that allows you to connect a circuit to your oscilloscope so that you can take measurements. We’ll have a look at the types of probes that are available, their most important specifications, and how to use them. Probes is a big topic on its own.

In this article, learn about oscilloscope probes and concepts like the probe attenuation factor, bandwidth, and loading effects that you must know to select the right probes for your projects.

All oscilloscope probes are rated by bandwidth capability. Bandwidth is the point on an Amplitude versus Frequency curve, where the amplitude drops to less than 3 dB (70.7%) of its beginning low frequency amplitude. Probe input capacitance is measured at the tip of the probe, using a BNC adapter ground sleeve.

As a by-product, the probe impedance and the oscilloscope input impedance function as a frequency invariant (flat frequency response) voltage divider which reduces the signal amplitude by a factor of 10.

Oscilloscope probes provide a physical and electrical connection between a signal source and an oscilloscope. Most probes consist of a probe head, a meter or two of flexible cable, and a connector which fits on the oscilloscope input.

2023年9月7日 · Every oscilloscope probe, along with the oscilloscope’s front-end, has a defined input capacitance that influences the bandwidth and impedance matching for a desired attenuation level.

2023年5月29日 · An oscilloscope probe is a device that makes a physical and electrical connection between an oscilloscope and DUT. There is no other way to connect an oscilloscope and your circuit without a probe.
