Oscilloscope and grounding device thereof

Abstract

The invention discloses an oscilloscope and a grounding device thereof. The grounding device comprises an adjusting rod and a ground pin, the adjusting rod is used for being rotatably connected to a probe, the ground pin is rotatably connected to the adjusting rod, and the ground pin and the adjusting rod are rotated to adjust the grounding distance between the ground pin and the probe. The grounding device can flexibly adjust the distance between the ground signal and the signal according to the ground signal, and the ground signal is spot-measured as stably as possible during testing, so that the possibility of misoperation can be reduced to the greatest extent, the grounding effect is better when the ground wire is short, the measured waveform is more accurate, the measurement result is more reliable, and meanwhile, the grounding device is easy to operate, the working efficiency of signal test can be improved, unnecessary damage to the mainboard caused by mistakenly touching the mainboard can be avoided, and therefore the cost can be saved.

Description

technical field [0001] The invention relates to the technical field of oscilloscopes, in particular to a grounding device. The invention also relates to an oscilloscope with the grounding device. Background technique [0002] At present, with the development of the Internet, the demand for information and storage has increased rapidly, and servers have gradually been applied to various fields of society. Before the server is put into the market, it is necessary to test various indicators and functions of the server, especially often using oscilloscope equipment to test signals. With the continuous update of PCIE, its rate is getting higher and higher, and the quality of its transmission signal is also more stringent. Therefore, the test needs to be carried out under a stricter environment. In order to improve the accuracy of signal measurement, the current test environment needs to be improved. [0003] In the prior art, when testers get the motherboard or other boards to...

Problems solved by technology

However, the first grounding design will cause glitches in the measurement waveform because the ground wire is too long, making the test results inaccurate; the second grounding design is likely to cause The case where the main board is short-circuited due to a spot test error

[0004] Therefore, how to avoid affecting the test results due to the inability to adjust the appropriate grounding distance is a technical problem that those skilled in the art need to solve at present
