Signal conditioning apparatus for debugging transmission/distribution engineering system

The utility model provides a signal conditioning device for debugging the transmission and transformation engineering system, which comprises a signal input protection unit, a Hall sensor, a secondary resistance of the Hall sensor and a signal output processing unit, wherein the signal input protection unit receives detected signals which are input from the outside, performs suppression processing on the input outrange detected signals, and transmits the detected signals after being processed to the Hall sensor, the Hall sensor collects the processed detected signals, input signals and output signals of the Hall sensor are mutually isolated on electricity, the Hall sensor generates a voltage signal which can be directly input in an oscilloscope on the secondary resistance of the Hall sensor, the signal output processing unit performs high-frequency suppression processing, bias adjustment processing, temperature compensation processing, wave filtering processing and the like on the voltage signal which can be
