Wireless probe for oscilloscope

Abstract

The invention provides a wireless probe for an oscilloscope. The wireless probe comprises a conventional wired probe, a sending module, a receiving module and a connecting cable, wherein the conventional wired probe and the sending module are in wired connection; the receiving module and the connecting cable are in wired connection; and the wireless probe is characterized in that the sending module and the receiving module are in wireless connection. In the wireless probe for the oscilloscope provided by the invention, the signal transmission is free from the limitation of cable length to a certain degree, so that position relation among the oscilloscope, a measuring person and a measured signal source is relatively flexible; when a plurality of signal sources are measured, the distance among the signal sources can be large; and the sending module and the receiving module are free from physical connection, so that the measured signal source can move relative to the body of the oscilloscope.

Description

technical field [0001] The invention relates to the technical field of oscilloscopes, in particular to an oscilloscope wireless probe. Background technique [0002] An oscilloscope is an electronic measuring instrument with a wide range of uses. It can convert electrical signals into images for people to analyze. The oscilloscope probe is an important part of the oscilloscope and has a crucial impact on the measurement application of the oscilloscope. According to the document "Principle and Selection of Oscilloscope Probes" (Measurement Technology, 2007, 27(3):49-50): Conventional oscilloscope probes are composed of probes, compensation circuits, wires, and connectors; The connection between the signal and the interface of the oscilloscope body is shown as a cable connection, that is, a wired probe. [0003] The following deficiencies exist in the actual measurement of the oscilloscope wired probe: 1) The length of the probe cable is limited, and the tester and the oscillo...

AI Technical Summary

Problems solved by technology

[0003] The following deficiencies exist in the actual measurement of the oscilloscope wired probe: 1) The length of the probe cable is limited, and the tester and the oscilloscope must be close to the signal under test; 2) When measuring multiple signals at the same time, the signal source is required to be relatively concentrated; 3) The signal under test The source and the oscilloscope body should be kept relatively still, otherwise the probe cable may be entangled or twisted.
