HI, i am using NI-4472 DSA card and will get input from all 8 channels. I am trying to build an application using LABVIEW 8 platform and i have to get different inputs at different channels. I want to use different software filters for different input channles. I am acquiring the signals using the DAQ Assistant but the problem is that i get a common output from the DAQ Assistant for all channels. If i try to use 2 differnt DAQ Assitants then it gives error. Please help me on this issue. I am using the Express Filter VI for Filtering purpose. I have set the Filtering Type as Smoothing Filter and then in filter specifications i have choosen Exponential Filter but i want to set different Time Constant values for differnt inputs. Please tell me how can i do that? I am stuck on this issue and just cant proceed forward for the last 2 days. I will be very thankful to you all who will help me.
