Problems solved by technology
However, the current testing of product circuit boards requires specially trained technicians to use multimeters, oscilloscopes and other testing devices to check whether the circuit boards meet the corresponding technical indicators one by one. During the test, it is necessary to repeatedly move the electronic product according to the test items. Or test equipment, not only wasting manpower and material resources, but also wasting a lot of time
In addition, technicians will inevitably make mistakes during the test, resulting in inaccurate test results

Embodiment Construction
[0009] like figure 1 As shown, a test system 10 for testing an electronic product 30 includes a test interface 12 , an instrument unit 14 , a main controller 16 , a signal generator 18 and a switching unit 20 .
[0010] The test interface 12 is the input / output (Input / Output, I / O) interface of the test system 10, which includes a plurality of test pins, respectively connected to the corresponding test points of the electronic product 30, such as the signal input port of the electronic product 30 , the signal output port, the power port, and the ports of the components to be tested in the circuit board of the electronic product 30 are connected. Correspondingly, the above-mentioned multiple test pins can be divided into output test pins and input test pins. Wherein, one end of the output test pin is connected to the signal input port or the power supply end of the electronic product 30 , and the other end is connected to the signal generator 18 through the switching unit 20 . ...

A testing system for measuring an electronic device includes a main controller for generating a control signal, a signal generator for outputting a predetermined test input signal according to the control signal, an instrument unit having a plurality of instruments, and a testing port having a plurality of probes. The plurality of probes connects corresponding testing points of the electronic device to the signal generator and the instruments. The predetermined test input signal is transmitted to the electronic device via the testing port. The instrument unit processes a test result signal outputted by the electronic device and outputs a result data. The main controller receives the result data and computes whether the result data is within a predetermined range. A related testing method is also provided.
Description
technical field [0001] The invention relates to a test system, in particular to a test system and method for testing electronic products. Background technique [0002] With the rapid development of electronic technology, the functions of electronic products are becoming more and more diversified, and the product assembly technology is becoming more and more sophisticated. Correspondingly, product functional testing is becoming more and more important. However, the current testing of product circuit boards requires specially trained technicians to use multimeters, oscilloscopes and other testing devices to check whether the circuit boards meet the corresponding technical indicators one by one. During the test, it is necessary to repeatedly move the electronic product according to the test items. Or test equipment, not only wasting manpower and material resources, but also wasting a lot of time. In addition, technicians will inevitably make mistakes during the test, resultin...
