Amplitude Modulation visualization issue

Hello. I've got the following problem:

There's a 800 Hz sinewave which must be carried by a 16000 Hz sinewave. However, what I see on the scope is that the AM signal has its maximums both at minimums and maximums of the 800 Hz sinewave. Maybe something "doubles" and I cant get what's that. Here's a picture:

And the scheme I'm using:

I've generated my 800 Hz sine with Signal Generator, and 16000 Hz with Signal Generator 1. Sampling rate of scope: 33600 Hz. I haven't got a clue what's going on!

That is the correct result. See Product-to-sum and sum-to-product identities (link) for the maths underlying it.

Thank you so much. Currently learning modulations, I was afraid there was something wrong. I appreciate your help!

As always, my pleasure!
