Abstract
Description
technical field
[0001] The invention relates to an initialization method using a pulse stepping motor frequency modulation filter in the communication field, and is particularly suitable for products using a pulse stepping motor frequency modulation filter with large output and high accuracy requirements. Background technique
[0002] The filter needs to be initialized in the R&D and production process of the pulse stepper motor frequency modulation filter, and 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 that could reduce manual operations to avoid errors and improve test efficiency. However, this kind of device can be used in relatively low frequency bands and filter products with low precision requirements. When used for filters in higher frequency bands, the test accuracy is not enough, so that manual operatio...
Examples
Embodiment Construction
[0039] refer to figure 1 , the method is realized by a test platform composed of a computer 1, a motor driver 2, a filter 3, a network analyzer 4, a regulated power supply 5, and the like. It uses computer 1, motor driver 2, filter 3, and network analyzer 4 to form a loop. Computer 1 controls the network analyzer 4 and motor driver 2 according to the parameters set by the user, and collects the filter process data tested by the network analyzer 4. , and the filter characteristic data is collected after several cycles. And the initialization data required by the filter is generated after calculation by computer.
[0040] refer to figure 1 , the USB interface of the computer 1 is connected to the GPIB port of the network analyzer 4 through a USB-GPIB adapter card; the COM interface of the computer 1 is connected to the RS232 interface of the motor driver 2 through a cable; the motor driver 2 The power supply is provided by the regulated power supply 5 with two power supplies ...
