I have the kit 8016 as my signal generator. Is it posible to create a signal existing from 2 sinewaves for example 1khz and 1.1 khz so I can measure IMD?
It is possible.
Generate a library file as a sum of a waveforms containing 10 periods and 11 periods.
Here you have a link to download such a waveform and the Excel sheet used to calculate it:
box.net/shared/1e9869um4l
To get the output frequency 1kHz +1.1kHz you have to set the generator frequency to 100Hz.
(Use 1kHz frequency range to get max number of samples per cycle - best quality.)
Try also frequency slightly different than exact 100Hz. When the wave is not synchronized to the scope sampling frequency you get better spectrum due to more random sampling.
