Automatic test system based on performance index of frequency hopping co-located filter

Abstract

The invention relates to an automatic test system based on the performance index of a frequency hopping co-located filter. The automatic test system comprises 4 parts: one special test fixture 2, one frequency hopping co-located filter to be tested 4, one preset program computer 1 and one network analyzer 3, wherein the RS232 interface of the preset program computer 1 is connected to the RS232 interface of the special test fixture 2; the USB interface of the preset program computer 1 is connected to the GPIB interface of the network analyzer 3; the A0-A7 interface of the special test fixture 2 is connected to the A0-A7 interface of the frequency hopping co-located filter to be tested 4; the RFIN and RFOUT interfaces of the network analyzer 3 are respectively connected to the RFOUT and RFIN interfaces of the frequency hopping co-located filter to be tested 4; the four parts are combined into a whole; the special test fixture 2 is provided with an automatic test mode and a manual test mode; the network analyzer 3 is used for testing the performance index of the frequency hopping co-located filter to be tested 4 and transmitting the test parameter into the preset program computer 1. The system has the advantages of high degree of automation, high testing efficiency, low cost and the like.

Description

Technical field [0001] The present invention involves a test system for a filter, especially an automatic test system based on the performance index of frequency jumper. Background technique [0002] Frequency jump technology is one of the main anti -interference methods in tactical wireless communication, and the frequency jump filter as the filter device of the transmitting system terminal and the pre -selected device at the front end of the receiving system directly affects the quality of the receiving signal in the system; due to frequency jumpThe center frequency of the filter is changed by changing the frequency of the channel, so it can improve the resistance of resistance and band external interference of the communication system, thereby improving the comprehensive anti -interference ability of the system and networking capacity. [0003] Frequency jump filter is widely used in large communication systems, such as: aircraft, ships, cars and other communication platforms....

Problems solved by technology

In addition, in the development, production process and engineering operation, the co-site filter must be tested. Since each co-site filter has hundreds of working sub-filters, in the face of a large number of testing, data processing and screening tasks, relying solely on Testers do it manually, and the workload is very heavy, which is not conducive to product performance improvement and mass production
