High-speed radiated spurious emission automated test system and method thereof

A high-speed radiated spurious emission (RSE) automated test method, comprising following steps:

• disposing a device under test (DUT) on a turntable of a RSE test chamber and setting an operation mode based on a measurement requirement according to a wireless technology specification of the DUT via a test module in a computer by a tester so as to start a high-speed RSE automated test process;
• setting measurement system parameters within a setting range provided by the test module according to measurement items/frequency band/country needed by the DUT in order to finish settings of the operation mode and the measurement system parameters;
• selecting paths or RF filters via controlling a filter switch box by the test module, and controlling a movable stirrer, inside the RSE test chamber, to change a position of the movable stirrer by an I/O control box, and controlling the turntable to rotate to change a direction of the turntable, and implementing an operational procedure set by the test module, and receiving a RSE test signal generated by the DUT via a receiving antenna, and transmitting the RSE test signal to a spectrum analyzer by the receiving antenna in order to obtain a measured value (dBm/MHz);
• reading the measured value, and executing a calculation and a compensation for the measured value, and exporting a test result of simulating semi/fully anechoic chamber by the test module;
• outputting and displaying the test result by the test module;
• determining whether the test result conforms to a specification requirement of the DUT according to the test result displayed by the tester, and returning to an initial step to re-execute setting and testing when the test result fails to conform to the specification requirement of the DUT, or proceeding to a next step when the test result conforms to the specification requirement of the DUT;
• and
• saving test data in a designated path by the test module, and analyzing the test data saved and performing a difference comparison to generate and display a report to finish the high-speed RSE automated test process.
