Abstract

The invention provides a graphic control radio frequency switching matrix system mainly comprising an embedded graphic control processor S3C2440, a controller area network (CAN) bus, a 6-level coaxial switch, a first high-pass filter, a second high-pass filter, a low-pass filter, a first wave trap, a second wave trap, a third wave trap, a first amplifier and a second amplifier. According to the graphic control radio frequency switching matrix system, the problem that different tested items need different signal processing paths during the testing process of radio frequency terminal equipment is solved, so that all test links for approving radiation disturbance and stray radiation indicators can be systematically integrated, errors caused by manual test are prevented, and the testing accuracy and the testing efficiency are improved.

Description

technical field [0001] The invention belongs to the field of electronic technology / communication, and relates to a radio frequency switching matrix system based on graphic control, which is used to approve the switching unit of the radiation disturbance and radiation spurious test system, and is especially used in the radio frequency index test and integration of the radiation spurious wireless terminal. Build the test system. Background technique [0002] Conventional terminal radio frequency automatic test system refers to the automatic test system that adopts computer control to automatically complete call establishment, link switching, signal measurement, data calculation and processing, and output test results.
