2021年5月3日 · An oscilloscope probe is a device that makes a physical and electrical connection between a test point or signal source and an oscilloscope. Depending on your measurement needs, this connection can be made with something as simple as a length of wire or with something as sophisticated as an active differential probe.

2017年6月29日 · This article looks at various types of oscilloscope probes and how to use them. Let's Talk Oscilloscope Probes...in General Terms. An oscilloscope (aka scope or o-scope) is a very powerful tool—and arguably the most used piece of equipment—for electrical engineers or anyone else wishing to measure electrical characteristics of electronic ...

Keysight offers a broad range of passive probes with various attenuation ratios and input impedance specifications to optimize the dynamic range and loading considerations of your oscilloscope ground-reference measurements.

2017年7月12日 · Passive probes offer a good way of connecting an oscilloscope to the device or circuit under test. They are low cost, reliable, and offer reasonable signal integrity when used knowledgably. This article will explore passive probes from the theory of operation through basic adjustments and use.

2024年2月20日 · Oscilloscopes enable engineers to visualize signal waveforms. They measure the amplitudes of voltage signals over time, display their waveform shapes, and calculate key characteristics like peak-to-peak voltages, frequencies, pulse widths, rise times, fall times, modulation, timings, and more.

You should use a scope probe for measurements when: The circuit impedance is approaching the input impedance of the scope, or The measurement includes high frequencies or fast edges and it’s important to measure these accurately, or

Your oscilloscope must be physically connected to your test circuit in order to make a measurements. This happens via a test probe. A probe is a device that conveys the signal to be measured from the test circuit to the oscilloscope.

In this article, we explore the four main probe types - passive, active, differential and current - and explain their characteristics. Read on to learn which probe you need for your measurement! Passive probes are characterized by their simplicity and lack of active components.

Whether you need the high bandwidth and low loading of an active probe, an easy way to connect to surface mount ICs or a passive probe to measure high voltages, there are a wide selection of high-quality probes and accessories for your Keysight Technologies, Inc. …

2017年7月21日 · Active probes offer greater bandwidth and lower input capacitance than passive probes. In this article the characteristics of active probes relative to passive probes will be demonstrated. Both single-ended and differential probes will be studied, along with the proper use of probe accessories. Why use active probes?
