User FIR Filter Coefficient File Download Problems
Data Requirement Reminders
To avoid user FIR filter coefficient data download problems, the following conditions must be
met:
1. Data must be in ASCII format.
2. Downloads must be in list format.
3. Filters containing more symbols than the hardware allows (64 for Real Time and 512 for
ARB) will not be selectable for that configuration.
Table 4-5 User FIR File Download Trouble - Symptoms and Causes
Symptom Possible Cause
ERROR -321, Out of
memory
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.
