I am trying to generate the plot from Keysight N9320 Spectrum analyzer .trc file from https://www.mathworks.com/matlabcentral/fileexchange/22908-read-spectrum-analyzer-trace-file but MATLAB can't read it and error is
Unrecognized field name "XStart".
Error in readsatf (line 139)
freq(index) = struct.XStart + (index-1)*struct.XScale/struct.XNum;
because file don't contain "#" headers and all the data is unreadable is there any other way to access these results from the .trc file.

Hey Muhammad,
The error message “unrecognized field name ‘XStart’” indicates that the field name ‘XStart’ does not exist within the 'struct' structure. Verify if the field ‘XStart’ is defined and in order to check this, you can make use of ‘isfield’ function. For more information on ‘isfield’ function you can refer to this documentation:
For reading the 'trc' files, you need to consider the underlying data format. If you are looking for alternative ways for reading the 'trc' file, then you would find the following MATLAB Answers useful for your case:
I hope this resolves your query!
