Description

technical field [0001] The invention relates to the field of comprehensive testing instrument testing, in particular to a WLAN signaling testing system and testing method. Background technique [0002] Usually, a WLAN signaling comprehensive tester is used. The DUT test TX signaling solution is to collect the signal of the WLAN comprehensive tester, then pass through the RF board and then to the baseband board, and finally pass through the FPGA (Field-Programmable Gate Array, that is, field programmable Gate array) analysis, to analyze the PHY layer (physical layer), MAC layer (media access control layer) information; the biggest difficulty of this method is that the FPGA needs to implement the WLAN MAC layer protocol and the corresponding MAC layer state machine. [0003] The PHY layer first analyzes the synchronization code, and then notifies the MAC layer that PHY_CCA is in the busy state. The PHY layer performs data analysis according to the corresponding synchronization...

Problems solved by technology

Most of the time is spent on controlling the PHY layer and the MAC layer control state machine. The automatic test of DUT signaling signals usually needs to cooperate with Ethernet data to automatically perform data interaction. At this time, the upper layer of the FPGA must analyze the Ethernet data. Because of this The reason is that the signaling test of the FPGA solution is very complicated and inefficient
