Abstract

The invention discloses a filter automatic testing device and a filter automatic testing method. By setting an automatic loading and unloading device, errors of test parameters or indexes brought in by manual operation are effectively avoided, and physical flaws brought by the manual operation can be avoided. An automatic calibration member is arranged in a test fixture, thus automatic test accuracy degree of a filter is improved, the de-embedding at different temperatures is realized, and the external error factors of the filter during the high and low temperature testing process are minimized. By arranging the automatic loading and unloading device in a high and low temperature test chamber, the test efficiency problem in the high and low temperature testing process is solved, the laborcost is reduced, a large amount of time consumed by clamping is shortened, the automatic feeding can be identified automatically, unqualified filters are directly placed separately, and the automaticdetection and screening are realized.

Description

technical field [0001] The present disclosure relates to the field of filter testing, in particular to a filter automatic testing device and testing method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] A filter is a device that filters waves. "Wave" is a very broad physical concept. In the field of electronic technology, "wave" is narrowly limited to the process of describing the fluctuation of the value of various physical quantities with time. This process is converted into a time function of voltage or current through the action of various sensors, which is called the time waveform of various physical quantities, or called a signal. The signal may be distorted by the environment and interference in every link of its generation, conversion and transmission, and even in quite a few cases, the distortion is so serious that the signal...
