RFtoolbox problem to save files that was changed in frequncies

Hi,

I am trying to open S-parameter and save it in different frequencies:

% Callbacks that handle component events

methods (Access = private)

% Button pushed function: OpenFileButton

function pushed(app, event)

global myhs

global myhs1

[file,path,indx] = uigetfile({'*.s*p','*.S*P*'})

filename= [path file];

myhs = sparameters(filename);

myhs1=myhs;

msgbox('File loaded ok', filename);

Lastfreq=myhs.Frequencies(end);

myfreq=linspace(0,Lastfreq,10);

myfname = 'test1.s32p'

rfwrite(myhs, myfreq, myfname) -> this fail with error why ??

Error using rfwrite

No value was given for 'test1.s32p'. Name-value pair arguments require a name followed by a value.

I am opening S32P file, so why does this fail ?

Thanks,

Roee

Hi Roee,

I understand that you are facing an issue while saving S-parameter into different frequency as touchstone file using 'rfwrite' function.

The input argument for 'rfwrite' function are data (Number of ports and frequencies), freq (Values of frequencies) and filename of the touchstone file. Please modify your 'rfwrite' function line as

>> rfwrite(myhs.Parameters,myfreq,'test1.s32p')

Ensure that the number of ports of the S-parameter file which you read and the extension of new touchstone file are same.

For example, if the numer of ports of the S-parameter file read is 'n', then the filename of new touchstone file should be 'test1.snp'.

For further information regarding 'rfwrite' function, please refer the below documentation link.

I hope this helps.

Thanks
