2017年6月29日 · The best approach, for matching a probe with a scope, is to first choose a probe whose capacitance is within the range of your scope and then fine-tune the probe's capacitance by adjusting its compensation network using the probe's trimmer capacitor, if possible.

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 test the electrical signals.

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 circuit operation and signal transmission.

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. The probe head allows you to hold the probe while you connect the probe tip to the test point. Often,

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 …

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

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.

2017年7月21日 · Active probes offer the benefits of increased bandwidth and lower probe loading. Differential probes add the value of ground isolation and the reduction of common mode signals. Proprietary interfaces fully integrate these probes into …

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.

2025年1月21日 · An oscilloscope probe makes physical contact with a test point and transmits electrical signal data from the circuit under test to the oscilloscope. There are several types of oscilloscope probes that cater to different test and measurement needs, including passive, active, differential, and current probes.
