Dear All ;
I want to decide whether to buy two cards of NI-9234 with 4 channel or one card of NI-9231 with 8 channels for sound and vibration application. As you can see in the attachment, I compared these two cards, their technical specifications are the same. Only NI 9231 needs Coaxial Male to BNC Female . However, I expected that since NI-9231 has 8 channels, its price would be double the price of the NI-9234 but it is not. So if you were me, do you buy two NI-9234 or one NI-9231?
thank you in advance for your help
Best regards
Mahsa
