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.
