Abstract

The invention discloses a self-stabilizing conducting comb signal source. The signal source comprises a shielding outer shell, a signal wire and a plug that are externally connected, and a charging protection module, a rechargeable battery and a circuit board that are built-in, wherein the circuit board comprises a boosting voltage-stabilizing circuit, a linear voltage-stabilizing circuit, a crystal oscillating circuit, a fractional frequency choosing circuit, a fractional frequency shaping circuit, a stepped shaping circuit and a balance output circuit; a charging power source charges the rechargeable battery through the charging protection module; and the rechargeable battery supplies power to the circuit board so as to form a comb spectral line through the circuit board and output the signal through the plug. The self-stabilizing conducting comb signal source has the advantages of simple structure, convenient operation and stable property, is mainly used for checking the accuracy of an electromagnetic interference test system or periodically checking the device in the laboratory, and has a function of standard substance.

Description

technical field [0001] The invention relates to a multi-spectrum standard signal source for testing electromagnetic compatibility (EMC) conduction projects in the radio field, in particular to a self-stabilizing conduction 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 the electromagnetic compatibility (EMC) conduction items of electrical products. The test site is carried out in a shielded room, and multiple devices are connected to form a test system: the power plug of the EUT of the product under test is connected to the artificial power network LISN, which provides power for the product under test, and picks up the signal generated by the product under test at the same t...
