Abstract

The present disclosure discloses an automatic filter testing device and a testing method. By setting an automatic loading and unloading device, errors in test parameters or indicators caused by manual operations can be effectively avoided, and physical flaws caused by manual operations can be avoided. , set the automatic calibration parts in the test fixture, improve the automatic test accuracy of the filter, realize the de-embedding at different temperatures, and minimize the external error factors in the high and low temperature test process of the filter; the automatic loading and unloading device Set in the high and low temperature test chamber, it solves the problem of test efficiency in the process of high and low temperature testing, and reduces labor costs, reducing a lot of time consumed by clamping, and automatic feeding can automatically identify and directly remove unqualified filters Placed separately to realize automated detection and screening.

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...
