Aiming at the current power line carrier communication module power consumption test equipment

there is a low dynamic power consumption response and low AC power test accuracy. The article deeply analyzes the key technical requirements of the communication module dynamic power test

focusing on a design scheme of the power tester.The paper introduces the working principle of the power tester

gives the circuit design scheme of DC power consumption and AC power consumption

and analyzes the calculation methods of static power consumption and dynamic power consumption in detail. Finally

the power consumption test results of various measurement systems are compared

and the test data is analyzed to conclude that the power test data is stable and reliable

and the accuracy is high.
