PXI 4461 Coupling

[wuyang]

Hi, all,

I am now using PXI 4461 to acquire data. This DAQ can provid AC or DC coupling, however I can not find this option in DAQ assistant subvi. I tried to modify this subvi, but it looks like that it is not a correct way. I attach what I have done and hope someone can help me to work it out. Thans a lot

Wu,

You are very close! You're exactly correct in thinking that you need to add a DAQmx Property Node into the subVI. However, you'll need to move it from where you've initially placed it. I recommend that you put that same node immediately after the DAQmx Create Virtual Channel inside of the False case structure. Making this change will correctly enable AC Coupling for your input channel.

Thanks!
