Abstract

The invention provides a power supply ripple test device. The power supply ripple test device comprises a test shell, a display module and a blocking module, the test shell covers the outside of the to-be-tested module, a positive electrode contact end and a negative electrode contact end are arranged in the test shell, the positive electrode contact end is connected with the positive electrode of the to-be-tested module, and the negative electrode contact end is connected with the negative electrode of the to-be-tested module; a display module; and one end of the blocking module is connected with the positive electrode contact end and the negative electrode contact end through a first connecting line, and the other end is connected with the display module through a second connecting line. When the power supply ripple and noise are tested, only the positive electrode contact end and the negative electrode contact end of the test shell need to be clamped at the two ends of the power supply to be tested, a worker does not need to hold the probe all the time, convenience is improved, and force is uniform in the testing process. And moreover, the ripple and noise of the power supply are tested in a clamping manner, repeated welding is not needed, a large amount of welding time is saved, and the operation is simple and efficient.

Description

technical field [0001] The invention relates to the technical field of power supply testing, in particular to a power supply ripple testing device. Background technique [0002] With the rapid development of science and technology, the power consumption of electronic products is getting smaller and smaller, the power supply voltage is getting lower and lower, the accuracy of the output voltage of the power supply is getting higher and higher, and the tolerance of electronic products to ripple noise is getting smaller and smaller. Most electronic products need to consider the signal integrity of the DC power supply when designing, and power supply ripple noise, as one of the important indicators of power integrity, has become a must-test item in the product testing process. [0003] There are about three popular power supply ripple and noise test methods at present, and the test methods adopted by each company are different. The first test method is to use the standard activ...
