Persistant data with NI 9239 in Real time

[Gautam Dee]

Hi

I have a ni 9014 micro controller with 9104 chassis  and I am trying to pick up analog signals with a 9239 card. For some reason the 3rd and 4th channels show persistant saw tooth and square waves even if a signal generator is connected to them.  I cant think of any reason why there is a problem with jsut the 2 channels of the four. Can someone please help me out with this issue ?

Thanks

Hi Tamanna,

Is your signal source grounded or floating? Do the faulty channels show only either a sawtooth or a square or both together as ajumbled signal?

Hi Ipshita

I had my fifo input connected to some static values. That was a silly mistake, thanks for replying though 🙂
