WLAN MIMO Test in Manufacturing
Switched MIMO
• Sharing analyzer by fast switching to measure each
MIMO channel in turn
- With any STBC and scrambling turned off in the DUT, built in switching in
each EXM E6640A TRX sequentially captures from successive bursts
- Agilent measurement software reconstructs the 2 MIMO streams then
performs a full set measurements, just as in ‘True MIMO’
