plot harmonic output of oscillator versus frequency

hi
i have a microwave oscillator and analysis it with harmonic balance in ADS software , i want to plot spectral of output signal versus frequency instead of harmonic index ,but i can't do it ,i just can plot spectral of signal versus the harmonic index
please help me

Hi,

I do not have access to ADS software anymore but as far as I remember, instead of just plotting the function, select PlotVs and choose "freq" variable as the variable for the x-axis.

As I said, I do not have the software open in front of me, so this is all from memory. It should be something along these lines.
