    Compute the average power measurement of the generated voltage signal.

    x = complex(rand(15000,1)-0.2,rand(15000,1)-0.2);
pm = powermeter(ComputeCCDF=true);
averagePower = pm(x);                            % power in dB

    Plot the computed coordinates of the CCDF curve.

    [relpower,prob] = ccdf(pm);
semilogy(relpower,prob)
xlabel('Relative Power (dB)');
ylabel('Probability (%)');
ylim([0 125]);
grid on;
title('CCDF Measurement');

    Figure contains an axes object. The axes object with title CCDF Measurement, xlabel Relative Power (dB), ylabel Probability (%) contains an object of type line.

    Input Arguments

    collapse all

    Power meter, specified as a powermeter System object™.

    Output Arguments

    collapse all

    Relative power in dB, returned as an N-by-M matrix. M equals the number of columns in the signals provided and N equals ceil(PowerRange/PowerResolution) + 1.

    Data Types: double

    Probability in percentage, returned as a matrix. The probability that the instantaneous signal power of the jth channel is above its average signal power by relpower(i,j), in dB, is prob(i)/100.

    Data Types: double
