Hi,
as per x band prototyping system, the solution is scalable like 1 stingray board supports 32 elements, 2 will support 64 elements .
As of complete system , AD9081 ( 4 channel ADC and DAC) is connected ZCU 102.
Can single ZCU 102 board can be used to connect to 2 AD9081 boards for more number of channels or we have to use 2 ZCU 102 board for 8 channel prototyping
