% temppha(j)  = 0;
        % Measure duty-cycle N times
        fprintf(os,'MEASUREMENT:IMMED:TYPE PK2PK');
        fprintf(os,'MEASUREMENT:IMMED:VALUE?');
        temppk2pk (j)= fscanf(os,'%f'); %Read p2p value of the output signal. (1V per 100mm/s)

The fscanf is returning more than one value or is timing out and returning no value or what is returned does not start with a number. Assign the result of the fscanf to a variable and test the size of the result. Or better yet fgetl and examine the results to see what you get, and use sscanf on the character vector.
