Hi All,

i try to analyse an sin signal with an
digital spectrum analyser.
The Result looks like,

I can save the spectrum as a binary file.
The file includes several 16 bit complex information.

How to watch this with octave and calculate
the SNR ?

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")

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
