In the embodiment of the present invention, the wireless communication module is fixed on the test fixture or related test fixture equipment, and the radio frequency signal is transmitted with low loss through radio frequency probes or radio frequency connectors, and passed through the radio frequency power divider. The radio frequency signal is divided into multiple channels, and then after passing through the radio frequency power divider, the radio frequency signal is transmitted to the corresponding several radio frequency signal inspection modules.

Fig. 3 is a flow chart of detecting whether the fundamental wave power is normal according to the first signal of the four radio frequency signals in a wireless communication module inspection method for improving inspection efficiency according to an embodiment of the present invention.

In the embodiment of the present invention, the detection of the high and low frequency templates is to determine whether the quality of the radio frequency spectrum meets the design requirements by detecting the adjacent frequency leakage power. Generally, the selection of high and low frequency points is related to the bandwidth of the transmitted signal. For example, if a signal with a bandwidth of 125khz is selected in the example of the present invention, it is qualified to judge that the power of the center frequency point ±500khz is lower than -40dbm. The actual power should be determined by the characteristics of the detected signal, and its key adjacent frequency leakage indicators can be detected by this method.

The actual harmonic detection qualified value should be determined by the characteristics of the detected signal. This method can detect the quality of its mass-produced harmonics. Note that this can increase the signal of the third, fourth and other higher harmonics.
