In the embodiment of the invention, the high-frequency and low-frequency template detection judges whether the radio frequency spectrum quality meets the design requirement by detecting the adjacent frequency leakage power. Generally, the selection of high and low frequency points is related to the bandwidth of a transmitted signal, for example, if a bandwidth of 125khz signal is selected, the central frequency point with +/-500 khz power lower than-40 dbm is judged to be qualified. The actual power should be determined by the detected signal characteristics, and the key adjacent frequency leakage index can be detected by the method.

For example, the minimum signal receiving capacity of the signal to be detected is-129 dbm, and the allowable measurement error of 1dbm is added, the minimum power generator outputs a test signal of-113 dbm, so that the minimum-20 dbm output power can be sent by the wireless communication module, the test signal is put into the primary and secondary shielding boxes, and the test signal is attenuated to-113 dbm through the power attenuator in the master box, so that the cost is saved. And the actual harmonic detection is qualified.
