% The communication is over TCP-IP (LAN).
% destRate is assumed to be 200e6 if missing
% displayCorr is assumed to 0 (off) if missing
% Example: [corrFilter] = loadPxaEqFilter('pxa4')
% output of corrFilter is in time domain.
% NOTE: The equalization filter feature on the PXA must be ON for
this
% script to work. It can be EQ Hold ON.
%
% Typically followed with something like:
% writeMxgFir('a-n5182b-00211', 'EQ_1GHZ_62MHZ', corrFilter);
if (nargin<1 || nargin>3)
error('[corrFilter] = loadPxaEqFilter(pxaAddress[, destRate[,
displayCorr]]) -- destRate is assumed to be 200e6 if missing');
end
if (nargin<2)
destRate=200e6;
end
if (nargin<3)
