Abstract

The invention belongs to the field of testing devices and discloses a periodic signal waveform testing device. The periodic signal waveform testing device is featured by comprising a signal input unit, a keyboard unit, a PLC unit, a signal collecting and processing unit, a programmable controller and a display unit. The programmable controller controls the PLC unit according to a received signal input channel message, and inputs a corresponding to-be-tested periodic signal wave into the signal collecting and processing unit through the PLC unit. The signal collecting and processing unit comprises a first functional circuit and a second functional circuit. The invention controls the testing process by the programmable controller. The overall testing process can be automatically conducted, the testing time is short, and the accuracy is high.

Description

technical field [0001] The invention belongs to the field of testing devices, and more particularly relates to a periodic signal waveform testing device. Background technique [0002] Periodic signal waveforms widely exist in various electronic products and are important indicators to measure product performance. Therefore, waveform testing plays an extremely important role in electronic product development and electronic measurement. At present, the measurement of the periodic signal waveform generally adopts the manual detection method, that is, an oscilloscope is used to test the indicators of the periodic signal waveform. However, this detection method is inefficient and relies too much on the test accuracy of test instruments and the test skills of testers. Contents of the invention [0003] In view of the above defects or improvement needs of the prior art, the present invention provides a periodic signal waveform testing device, which is reliable, convenient and hi...
