Embodiment Construction
[0015] refer to figure 1 , the test equipment includes the ground station working equipment composed of antennas, high-power amplifiers, up-converters and integrated basebands connected in series on the same link; and the test switch network and spectrum analyzer of directional couplers connected in series on the link. The ground station is equipped with calibration and testing equipment. The antenna, high power amplifier, up-converter and integrated baseband are connected in series on the same link, and the baseband signal is sent to the high-power amplifier (high-power amplifier, HPA) through the up-converter, and the high-power amplifier amplifies the signal power and sends it to the antenna. On the link, a test switch network and a spectrum analyzer are connected in series from the directional coupler. The directional coupler extracts the uplink signal, which is switched to the spectrum analyzer through the test switch network to read the power level.
