Does anyone know how to build a sine wave with specific jitter amplitude and frequency?
The ideia is to load the signal with jitter to 33220A
No one else has this question

I am not sure if you want to have amplitude jitter with a specific frequency or if you also want to have frequency jitter. In reality, the two are related because the amplitude jitter will advance/delay the trigger point and look like different frequencies.
If you just want to have amplitude jitter (with the frequency jitter being the fallout), you can do AM with the sine wave being the carrier and the noise function as the modulating waveform.
If you want to have both amplitude and frequency jitter, you can create a noisy sine as an arbitrary waveform, use that as the carrier for FM with the noise function being the modulating waveform. In this case, you will see correlations in the amplitude jitter because the sine wave is an arb and not truly noisy.
The 33500-series generators will allow you to add noise to the waveform within the instrument, rather than having to use modulation.
Hope one of these ideas works for you.
