I saved the measured data to use in Matlab. There are no headings for the 17 columns of data that the UXA saves. Does anyone know which column is what??
You can find information about the returned data for complex spectrum measurements in the IQ Analyzer Mode User's & Programmer's Reference. The information of use to use there starts on page 106 of that document. When you use MEASure:SPECtrum[n]? without specifying "n", you get 17 columns of data corresponding to the listing in that link starting on page 107. Some columns have multiple values. That is, the columns will look like:
Column 0 is documented as “Returns unprocessed I/Q trace data…
Column 1 has 11 different things, shown below as results 1-11
Column 2 is “Returns the trace data of the log-magnitude
versus time. (That is, the RF envelope.)
Column 6 is not used
Column 8 is not used
Column 13 has 13 different data values
Column 17 is Averaged delta phase trace in radians (-999
when I/Q Magnitude and Phase Delta Results
When you look at the guide I linked above you should see how each column listed here corresponds with a "major" N value in the chart.
Hope this helps.
