Hi Francesco,

thakns for your Answer.

i wrote a small script:
filename = "spectrum.m";
fid = fopen (filename, "r");
[val, count] = fread (fid, 100, "uchar", "native")
fclose(fid);

But i want to watch the original komplex values instead of int values.
How to ?
As i know my Spectrum Analyser produces I/Q Signals, so there should be
2*16 bit values. Each 16 bit value is complex.

Regards Markus
