Description

technical field [0001] The invention relates to the field of radio frequency technology, and in particular, to a radio frequency test system and a radio frequency test method. Background technique [0002] In the manufacturing process of electronic equipment, it is often necessary to perform radio frequency testing on the circuit board of the electronic equipment to measure whether the power of the radio frequency signal transmitted from the circuit board to the antenna reaches a predetermined value, and perform relevant debugging according to the test results. [0003] Usually, a test seat is set on the circuit board, and the test seat is connected to the RF circuit on the circuit board. When the RF signal of the circuit board needs to be tested, the test line can be connected to the test seat. At this time, the test seat The path connecting the RF line to the antenna feed point can be cut off, so that the RF signal can be transmitted to the tester through the test line, so...
