Symptom Possible Cause

There is not enough memory available for the FIR coefficient file being
downloaded.
To solve the problem, either reduce the file size of the FIR file or delete
unnecessary files from memory.
ERROR -223, Too much data
User FIR filter has too many symbols.
Real-Time cannot use a filter that has more than 64 symbols (512
symbols maximum for Arb). You may have specified an incorrect
oversample ratio in the filter table editor.
