Define User FIR
Press this softkey to display a table editor where you can create and
modify FIR filters.
The FIR table editor allows a maximum filter length of 1024 taps (32
symbols with a maximum oversampling ratio of 32), but the instrument
hardware is limited to 32 symbols, an oversample ratio between 4 and
16, and 256 coefficients. If you enter more than 32 symbols, the
instrument cannot use the filter. Entering more than 16 symbols will
decrease the maximum symbol rate by half. If the oversample ratio is
different from the internal, optimally selected one, the filter is
resampled to the most optimal oversample ratio. For details on using
the FIR table editor, see “
