Description of the invention: [Technical field to which the invention pertains] The present invention relates to radio frequency (RF) technology, and more particularly to a test method for automatically scanning radio frequency. [Prior Art] The RFID receiver is widely used, such as FM radios and televisions. When manufacturing a product with a radio frequency receiving device, it must first scan the radio to ensure that it can operate positively. Conventional. Gas system ^ human operation a radio frequency # generator (radios frequency signaljenerator; RF signal 弘 (4), by changing the frequency of the RF signal generated and output - test signal to the device under test (device under t: st ' DUT "Through the purpose of the test. However, this method consumes labor and 2 is not economical and has the disadvantage of poor work efficiency. 15 I. Referring to the first picture, in order to improve the above problems, there will be more operators. The RF device (1) is connected in parallel to a mixer (10) (10) to form a center (3) 'and then transmits a plurality of test signals through the mixer (sentence synthesis - data stream (5), device under test (6) As long as the mixer is connected, it can receive the = test signal. 'However' because of the simultaneous use of multiple RF signals (4), the cost of setting up the signal center is greatly increased, and the cost is increased. In addition, the equipment in the center of ## is large in size, and it needs sufficient space for the installation when it is set up. However, it is necessary to fully test the method of scanning radio frequency, which has the above-mentioned missing and needs to be improved. 9722 is a flow chart showing the operation of a host according to a preferred embodiment of the present invention.
