Jaejeen,
There is no daqboard with the exact specifications you request. However, I can suggest you some alternatives:
1.- You can get a Signal Source board with at least four analog output channels; i.e., the NI 6711, and you can get an E Series board for the analog input channels. Finally, you can synchronize both of them.
2.- You can get a regular E Series Board, and you can use the two regular analog output channels, and the counters are other two analog output channels, but with the restriction to generate square waves only.
Hope this info is helpful.
