[0002] A field strength probe is a device used to measure the strength of an electric field, and a field strength probe with fast and accurate positioning function is a tool that can quickly and accurately locate the strength of an electric field. This type of field strength probe is usually used in electromagnetic compatibility (EMC) testing, radio frequency (RF) engineering, antenna measurement and other fields;

[0003] According to the authorized patent with announcement number CN217085243U, a field strength probe with fast and accurate positioning function is provided. The field strength probe with fast and accurate positioning function rotates the probe around its horizontal direction through an axial drive motor, moves the probe height through a linear module, and rotates the probe around its vertical direction through a radial drive motor. The field strength probe body can move in three-dimensional space, which is convenient for accurate positioning, fast adjustment, and convenient operation. It can cooperate with PLC automatic control to improve accuracy. At the same time, the probe part adopts a quick-install design for easy operation.
