The automatic initialization method is high in accuracy and efficiency, convenient to implement and suitable for various frequency ranges, an unattended initialization process can be realized, and the generated initialization data can be verified. Process data and a result can be saved as files, so that the process is traceable. The automatic initialization method is characterized in that a tested product is controlled while the test instrument is controlled, control over the tested product and control over the test instrument are conducted in a cooperative mode, manual operation is completely simulated, the process data are recorded, and human errors can be avoided.

Description

technical field

[0001] The invention relates to an initialization method for a frequency modulation filter using a pulse stepping motor in the communication field, and is particularly suitable for products using a frequency modulation filter using a pulse stepping motor with large output and high accuracy requirements. Background technique

[0002] The filter needs to be initialized during the R&D and production process of pulse stepping motor FM filter, while the traditional initialization requires manual operation of the instrument and control of the filter to collect filter characteristic data. Operation is error-prone. Subsequently, a test device was developed to reduce manual operations and avoid errors, and also to improve test efficiency. However, this device can be used in relatively low frequency bands and filter products with low precision requirements, and the test accuracy is not enough when used for higher frequency band filters, so that manual operation is sti...
