I was forgetting, the same behaviour apply for DC output mode.
Yes, of course. DC is just the programmed offset without any variation (AC signal). It is produced by a DAC and runs through all amplifiers/buffers just like any other waveform.
Very likely there is a separate DAC just for the offset, and its output is added to the main signal.
That way the main DAC can always have full resolution, i.e. all 14 (or whatever) bits can be dedicated to the signal waveshape and you still get a respectable offset range.

Sure i agree, lot bang for the bucks, i'm using it on a daily basis, works good and it's pretty.
The output amplifier is rather weak, as I understand it delivers full power only up to 25MHz.
What would be your main use ?
There are just two things I don’t like so much:
1) There is no front connector for a sync signal. Yes, very likely there is one on the back, but I hate it when things that I actually use a lot are on the backside.
2) The output amplifier is rather weak, as I understand it delivers full power only up to 25MHz.
o Yes there's a sync connector on the back. Sync only works up to 1MHz (which seems really low to me).

Ouch! 1MHz isn't great indeed.
Does that mean the sync output is a train of 1µs pulses instead of a squarewave?

It is a 1.5V, positive-going pulse, with a fixed pulsewidth of 500nS. (so when the channel output gets up to 1MHz the sync signal is a squarewave.)

Not in my case, amplitude is correct (0-5V) and with sweep function i get a 50% duty cycle square wave synced to sweep ramp, see attachment.
Here is a video on generating a 4-phase signal using two SDG2000X generators:
"Seems that the frequency counter leaks a 10 MHz signal to it's input."
We did identify a cross-talk issue that is causing this leakage to the frequency counter port. The factory tells me they are working on the problem.
Thanks for your comments.

Any information about fix for this?, I would assume this is an hardware issue and thus will only be fixed on newer units?
From which serialnumbers will this be fixed?
I may be totally wrong in this, but a great deal of frequency counters are so sensitive that any strong signal around them will be enough to cause it to count. Do we know that the 10M signal is indeed leaking into the counter input? Or is the counter just sensitive and 10M is the strongest signal around?
There are spectrum analyzer plots running around here showing the leakage. It's at a high enough level that it will mess up counting a 10 MHz signal. It also would give you a neat spur on the generator output.
