Implementing Band-Pass Filters in VeriStand

Issue Details

When we try to call a LabVIEW Model implementing a Band-Pass Butterworth filter or a Point-by-Point Mean filter from VeriStand we can pass data but it is not filtered properly, how can we implement one of these filters? 

Solution

If you are passing data from VeriStand to your LabVIEW model and the data is not being filtered you may need to create a custom device to implement this functionality within the NI VeriStand Engine. 

Additional Information

In a certain cases we are unable to perform Band-Pass Butterworth filtering or Point-by-Point Mean filtering on data that is passed from VeriStand to LabVIEW models. This is due to SubVIs within the LabVIEW model that can go idle and each time they are called thereafter they reset their internal buffer and fail to filter the data being passed through.
