Oscilloscope probe

Get Info From Multiple Sources. 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 devices. 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. Some probes include a switch on their handle.

This is the attenuation selector. Keysight’s high performance oscilloscope probes are engineered for superior signal access and measurement accuracy.

Whether you need simple passive probes, the high bandwidth and low loading of an active probe, or specialty probes for current or high voltage, we can meet your needs. Join Prime to save £2. Capacitive for Indoor and Outdoor.

Insulation and Vacuum Interrupters. Voltage Dividers and Voltmeters. See product details.

Customers also bought ref-tags-container-link 1-of over 0 for. Oscilloscope Probes. On most scope probes there is an adjustment to compensate the probe to improve its frequency response.

The oscilloscope probe along with its leads constitutes a high impedance in parallel with a high capacitance. So the end result is a high-Q resonant circuit, which will produce ringing, visible in the display and misleading if one were to assume it had something to do with the circuit under investigation.

While connecting the test circuit, the probe does not alter, load or disturbs the circuit and signal conditions to be analyzed. Part costs are kept low and what you get are EMI blocking probes with changeable, multipurpose tips. Bengaluru, Karnataka. Passive oscilloscope probes.

The probe attenuation is a nominal 1. To make accurate, actionable measurements it is critical to choose the correct oscilloscope probe for your signals. Compare : A wide selection of high-performance oscilloscope probes and oscilloscope probe accessories to help you get the most out of your scope. Without an appropriate probe the best oscilloscope is useless.

For that reason it is essential to choose the right probe to connect the circuit under test to your oscilloscope. Before choosing a probe, it is important to understand how probes work and how they are.

Sure, you could buy oscilloscope probes from Amazon or eBay.

Attenuated oscilloscope probes. To minimize capacitive loading on the device under test, most probes use a x(also called 10:1) attenuator.

The following note explains the adjustment technique using two example probes with different adjustment arrangements. The average oscilloscope probe has a bandwidth of less than 300MHz.

Current probes can have bandwidths of 60MHz to 100MHz or less. Furthermore, high-frequency voltage probes often cost over $10and slightly better current probes start at $000.

For power engineers who work for mid-sized companies, there is only one path: build your own probes. Warning: if you plan on using this probe for high voltages, you will need to use more insulation than in shown in this howto.

Specifications Parts Instructions 3. Probes are single-input devices that route a signal from your circuit to the scope. They have a sharp tip which probes into a point on your circuit. Understanding these factors is critical for anyone that needs to make accurate, actionable measurements. A probe lets you connect between the circuit of interest and the input of the oscilloscope.

Probes perform several important functions: They isolate the circuit from the scope, to minimize the effects of loading on the circuit operation. A Xis better than a piece of co-ax, but a Xprobe is more effective than a X1.

A Xprobe has the effect of reducing capacitance by a factor of ten. The trade-off is that is also attenuates the signal by a factor of ten. The Probe -Scope grows as you grow, giving you as many channels as you have USB ports, the probe scope is almost infinitely expandable to tens (or more!) of channels.
