I am using the DAQ Assistant to read 6 channels from a PXI-6281. The signals of interest are approximately 90mVAC (60Hz) with up to 250mV DC Offset. Can I programmatically subtract the offset from the acquired signals. I tried the Express filter to no avail.
Thanks,

Substracting an array from Dynamic Data Type bundle after DAQ Assistant doesn't work though. https://decibel.ni.com/content/docs/DOC-4441 provides a solution. Would you have a more simple and elegant solution?

What could be simpler or more elegant than an add/subtract function. Why would you subtract an array? You simply use a constant.

See pic of the vi (LabVIEW 8.5.1). After some time (from 2 to 20 hours of run time) a dt error comes up.

What is the error? Why don't you have the subtract function inside the case statement. Then you would not need that silly local variable.

Good call about the subtract.
