Not sure whether you can get the same deal locally; Rigol NA's website says "US and Canada only".

I will buy in USA today! I'll check that discount right now, thanks!
EDIT: I just saw it, great price, but the DHO1000 series does not have a logic analyzer and I would prefer to integrate it. While it has more bandwidth than the 900 and a larger screen, it lacks a built-in signal generator too. The AWG of the MSO5000 or the DHO900 are not wonderful, especially when compared to higher budget instruments, but they are sufficient for me to evaluate signal adaptation circuits for sensors. It seems to me that the alternative is still the DHO900 or the MSO5074 (hacked of course). Thank you!

Yep, the lack of AWG and LA really hurts those two families. Like what are you even supposed to do with a 2 channel scope alone? Cannot decode any serial protocol and see the results the same time. Siglent has this nice feature that you can connect an AWG to a scope with an USB cable and the scope will do Bode plot with it, Rigol, this is missing. It's only software. I don't see why would you buy that 12 bit scope, unless it's your 3rd scope or something.

I don't understand you tszaboo, sorry, my English is not good and I'm probably missing your point. The two oscilloscopes we are talking about have 4 channels and both have at least one AWG integrated (included in the cost, the MSO actually has two but both enabled by a hack). AWG in rigols have the same functionality of siglent that is external via USB and a added cost. I consider a disadvantage and external device that could be integrated inside the same device. Both have BODE analysis (with limitations in the DHO900 and apparently some bug) but from what I observe with the same functionalities as the siglent. It is true that the siglent has, according to the reviews, less noise than the MSO, but no less than the DHO900.
What would be your real point in favor of Siglent?

I see it, I have more noise in my old Agilent (rigol?), it's not relevant in digital signals.
--- Quote ---There's features to mitigate it but they usually come with conditions, like needing a repeating signal and averaging several copies of it together ("waveform averaging" mode).

Yes, abussing from the 8GSa/s I can average 6 points and still has the same bandwidth of the DHO900
--- Quote ---As noted earlier though, it's moot for digital work.

Agree, THANKS for help me

I was talking about the DHO1072 and DHO1074.

Ahhhh, ok, yes, I don't dispute that the DHO1000 model has better analog characteristics than the 900, but I need the logic analyzer and to a lesser extent the signal generator, but I need both.
