Automatic tracking peak detector

The invention relates to the technical field of peak detectors. The invention relates to an automatic tracking peak detector. The detector comprises a diode, a reset switch and a power supply. The diode, the reset switch and the power supply are connected through a wire. A clamping unit is arranged on the wire. According to the invention, the clamping unit is arranged in the middle of the wire, aplurality of working elements such as a diode, a reset switch and a power supply are separated, rapid decomposition and combination of the whole circuit are realized, only a conductor rod needs to beinserted into a conductor cap, a pressure plate is pressed several times by fingers, a plurality of telescopic blocks are ejected through air pressure, further, the conductor rod is clamped, and rapidassembly and connection of the whole circuit are realized. According to a method for converting high-frequency signals into peak signals, the peak signals are direct-current signals, a low-frequencydata acquisition instrument
