N2 - It's absolutely necessary to create distributed test system for distributed UUT. However, distributed test systems constructed by the existing test bus products such as GPIB, VXI, PXI and LXI are all wired communication network based, which cannot satisfy certain test requirements. In this paper, on the basis of research about wireless communication network expansibility of modern test instrument, the thesis puts forward wireless distributed test system based on WLAN, introduces topology architecture, MAC layer protocol and physical layer technology, and presents some solutions on the key issues such as real-time, clock synchronization and trigger synchronization, etc. As for clock synchronization, the paper describes synchronization mechanisms based TSF, TINY/MINI-SYNC algorithm and IEEE 1588 precise time protocol, and for trigger synchronization it presents methods based on command, event and time, etc.
