Radio-frequency element group testing system and method

An RF element group testing method, which is applied to an RF element group testing system, wherein the RF element group testing system comprises a signal generator, a testing platform, and a signal analysis unit;

• the RF element group testing method comprises steps:
• using the signal generator to generate a power signal;
• using the testing platform to receive the power signal and transmit the power signal to a plurality of tested RF elements disposed in the testing platform;
• making one of the plurality of tested RF elements output a first RF signal according to the power signal;
• adding an identification feature to the first RF signal to generate an identification RF signal;
• making each one of the rest of the plurality of tested RF elements output a corresponding second RF signal according to the power signal;
• using the testing platform to synthesize the identification RF signal and each second RF signal to form a corresponding synthesis signal and transmit the corresponding synthesis signal to the signal analysis unit;
• using the signal analysis unit to resolve each synthesis signal into the identification RF signal and the corresponding second RF signal according to the identification feature;
• restoring the identification RF signal into the first RF signal according to the identification feature;
• and
• calculating at least one signal-feature parameter of the first RF signal and the second RF signal.
