AI Technical Summary

Technical Problem

Existing technologies for evaluating the conducted safety margin of communication equipment containing antenna tuners (antenna tuners) have problems such as the test results being greatly affected by weather and environmental factors, changes in the internal structure of the equipment, or incomplete assessment of performance parameters.

Method used

The test communication device and the companion communication device adopt an autonomous frequency selection mode. The communication signal is simulated by loading a directional radiating antenna through a signal source. An audio analyzer or bit error rate tester is loaded at the test device to monitor the device status in real time and ensure that the device structure and internal circuit are not changed as much as possible during the test.

Benefits of technology

It improves the accuracy and repeatability of test results, reduces the impact of human factors, simulates actual communication scenarios, and the test results are not affected by natural environment and human factors, thus improving test efficiency.
