Description

Technical field [0001] The invention relates to the field of comprehensive tester testing, in particular to a WLAN signaling testing system and testing method. Background technique [0002] Usually a WLAN signaling tester is used. The TX signaling solution for DUT testing is to collect signals from the WLAN tester, then pass through the radio frequency board to the baseband board, and finally pass through FPGA (Field-Programmable Gate Array). The analysis of the gate array is to analyze the PHY layer (physical layer) and MAC layer (medium access control layer) information; the biggest difficulty of this method is that the FPGA must implement the WLAN MAC layer protocol and the corresponding MAC layer state machine. [0003] The PHY layer first parses the synchronization code, and then informs the MAC layer that PHY_CCA is in the busy state. The PHY layer performs data analysis according to the corresponding synchronization information data rate, and after the analysis is completed,...

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
