Abstract

The invention provides an automatic calibrator, a calibration system and a calibration method of testing equipment. The automatic calibrator comprises a controller and a gating module connected with the controller; the controller is used for sending a gating command according to preset setting information and controlling the automatic calibration of external testing equipment to be calibrated relative to corresponding external standard testing equipment; and the gating module is used for automatically gating the electric connection between the controller and a special testing channel of the corresponding standard testing equipment and the testing equipment to be calibrated according to the gating command. The invention solves such problems caused by manually inserting and pulling cables in the prior art as complex operation and large error, and the like.

Description

technical field [0001] The invention relates to an instrument calibration technology, in particular to an automatic calibration instrument for testing equipment, a calibration system and a calibration method. Background technique [0002] With the development of social economy, testing equipment is widely used in scientific research, military industry, electric power and manufacturing industries. Among all test equipment, signal generator and oscilloscope are the two most widely used test equipment. Since the test equipment itself is a complex electronic system, it is affected by many factors such as time and temperature environment, and the test accuracy will vary. Therefore, in order to ensure product performance, the test equipment must be calibrated regularly. According to the provisions of the National Metrology Verification Regulations, the indicators that the signal generator needs to be calibrated include more than 30 indicators such as frequency accuracy and level a...
