Abstract

The invention discloses a bistable radiation comb signal source, which comprises a shielding shell, a radiation antenna externally connected to the shielding shell, a charge protection module, a rechargeable battery and a circuit board, wherein the charge protection module, the rechargeable battery and the circuit board are arranged in the shielding shell; the circuit board comprises a voltage detection regulating circuit, a linear reducing regulating circuit, two crystal oscillation circuits, a frequency division selection circuit, a frequency division shaping circuit and a step shaping circuit; and a charge power supply charges the rechargeable battery by the charge protection module, the rechargeable battery supplies power to the circuit board to form comb spectral lines by the circuit board, and the comb spectral lines are output by the radiation antenna. The generated bistable radiation comb signal source has a simple structure and stable performance, is convenient to operate, and as a stable standard signal, is applied to the regular check of test equipment and environments thereof to check whether the accuracy of the equipment meets the requirement or not.

Description

technical field [0001] The invention relates to a multi-spectrum standard signal source for testing electromagnetic compatibility (EMC) radiation items in the radio field, in particular to a bistable radiation comb-shaped signal source. The comb-shaped signal source device is used as a stable standard signal for Daily calibration of test equipment and its environment to check whether the accuracy of the instrument meets the requirements. Background technique [0002] Domestic and foreign technical regulations have uniformly stipulated the method of testing electromagnetic compatibility (EMC) radiation items of electrical products. The test site is carried out in the CISPR elliptical open field or in an equivalent anechoic chamber, such as figure 1 shown. The test system consists of a standard CISPR elliptical open field, antenna, measuring receiver, etc. The tested product EUT and antenna ANTENNA are respectively on the two focal points of the ellipse. The interference sig...
