if it were a hardware fault, I'd expect the glitch to exist over a wider range of frequencies.

Although I realise it's been diagnosed unfixable in software by Rigol, I am not convinced. At that point I assumed non-linearity in the SA's mixer, but that doesn't add up either as you'd expect that behaviour to exist over a fairly broad frequency range.
I tried it at a number of levels too, in case it could be shown that the TG was operating non-linearly somewhere in the frequency chain: the error the 815 SA shows is much less with lower TG power, but the relative TG discontinuity remained the same at the 10MHz transition irrespective of power.
There is a definite discontinuity that occurs at 10MHz, but it was significantly less than that shown on the SA.

At least they should give the TG option for free because it's a faulty project.įWIW, a few weeks ago I did a test where I connected the triggers of a a scope and the 815 and let the TG sweep. I always think that if an instrument is not able to measure something is't just a bells and whistles flipper game. Not nice if I think I gave money to pay an engineer who is not able to fix this issue. If you own a 815-TG you will have it and believe me, every time I need to measure a filter in the HF region my eye falls always on that glitch.
The problem arise when you turn On the TG, the SA sweep forget numerous bits passing exactly on 10.000.000 Hz. It's confirmed by others with the HW as mine (check the original post for details), it was present in a brand new one by the reseller, it's present in all the 815-TG. Hi smgvbest, before to open the ticket with the Rigol I already checked what you are suggesting, it's confirmed by the Germany Rigol support that it's a common issue in ALL 815-TG and that they are not able at this time (already 1 year passed since I wrote them) to find a solution and that I have to keep it as it is.
