I don't know, i think it does..... ^-^

In attachment:
- noisy 1MHz into CH1.
- Math2 (F2) Average(C1)
- Math1 (F1) FFT on (F2)
- Math3 (F3) FFT on (C1)

First image are signals. Second image are  FFT-s. Different timebase for nicer FFT res.

You can also do this:  FFT(Filter(C1*C2)) in single math channel. And do that 4 times...

And also you can have Memory channel as a source. Which is interesting because that means you have original data saved instead of result. So you can later on change FFT parameters when comparing to something.

Siglent's math is on completely another level.. R&S don't have it on MXOx.. They are working on it though...

That's pretty impressive. Done on the SDS2000X HD, I assume? Which is unfortunately outside of my price range, and not a direct competitor of Rigol's DHO1000 series.

Ah, if only Siglent could make up their mind about the SDS1000X HD... With the increasing rumours about the Q1 release of the 800X HD outside of China, it seems uncertain again whether the 1000X HD will come here at all?

Yes that is 2000XHD, that is what I have.
But from what I hear that little one will be able to mostly do the same.
As for 1000XHD I'm sorry but I honestly don't know. I don't care much about rumors and I have no knowledge of official info on that topic.
I hope it does, it is an excellent scope in its class.

I tried it last night and got the message "not supported".
I'll try it again tonight 8)

You should rethink that statement.

FFT results cannot be the source for math operations, but Math (incl. FFT) can take channel traces, zoom traces, memory traces and math traces as operands.

But that was exactly the point, whether FFT can be used as a source and after I tested it again to be sure, I said no.
And I didn't mean anything other than that. :)
