Abstract

The invention relates to a signal detection equipment calibrating method based on a time-frequency parameter standard signal source manner. According to the signal detection equipment calibrating method disclosed by the invention, a standard signal source can be remotely controlled, the output information such as the time-frequency parameters of the standard signal source is collected, and comparative analysis is carried out on standard data and the output data of equipment to be detected, so that the data accuracy grade and operation suggestions of the equipment to be detected are given out. The signal detection equipment calibrating method disclosed by the invention can reuse a test plan, and particularly during the parameter setting in the aspects of equipment, instruments, signal sources, data collection, results and the like, the workload can be greatly saved through the reusing of the plan; meanwhile, the plan can be separated with a site test, the plan is prepared before the site test, and thus the site test time is shortened, and the using convenience of the calibrating method is improved.

Description

technical field [0001] The invention relates to the field of equipment calibration, in particular to a signal detection equipment calibration method based on a time-frequency parameter standard signal source. Background technique [0002] The accuracy of the measurement data of the signal monitoring equipment directly affects the quality of the product. In order to ensure the accuracy and reliability of the equipment, it must be calibrated when the model is developed and delivered to the user. The existing signal calibration methods include time-frequency parameter calibration and airspace parameter calibration of the signal. However, there are many problems in the existing technology in terms of time-domain parameter calibration and airspace parameter calibration. The process is complicated, the operation time is long, the operator is prone to fatigue and make mistakes, etc., so a new calibration method is required to calibrate the signal detection equipment.
