A commutator of composite video signal based on PXI bus

摘要:

介绍了基于PXI总线、多路视频信号转接卡PXI接口电路、转接功能和软件驱动的设计,实现了利用AD8111转接芯片完成了将单路信号转接到所需的通道上进行测试的目的。

Abstract:

Based on PXI Bus, a commutator of composite video signal is designed in this paper. It contains the PXI interface circuit, the commutating function part and the software driver. A thing is made to come true, which connects a composite video signal to a given channel using AD8111 in order to do a measurement.
