Rigol DHO804 Test and Compare Thread

As a main device, not a single 7" scope would be on my list, the small screen would be too tiring for me in the long run.
If that weren't the case and I had a tight budget and no scope yet, the SDS1104X-E and the DHO804 would remain.
However, since I need Bodeplot and the Rigol doesn't offer one, I would have to opt for the siglent.
That's quite a shame, because I like the DHO804 better in some areas (what exactly will follow).
And even if I had more money to spare, a DHO900S would be out of the question for me, as I consider it a rather superfluous model.
What can it do better than the 800, almost nothing.
If you don't need an LA, the device is a more expensive 800.
As things stand, I think the 800 series is the best of all the new Rigol scopes, no joke.
The "oddities" and the sometimes rather meager features can be forgiven for the cheap 800, as the owner of a DHO1000 or even 4000 I would feel a bit stultified in view of the fact that most of the hardware used there is also available for a quarter or eighth of the price with the 800 and the software and thus the operation is the same anyway.

I agree. If you could modify the DH800 to have a bigger display, it would be more or less equal to the way more expensive DHO models.

With the Siglent you have to add the cost and extra bench space of a signal generator. A DHO900 could compare very favorably to that.

If you're not going to use the LA then the DHO900 makes no sense at all. Some people might think it has a higher bandwidth but that's not really true and it's just more opportunity for aliasing.
The DHO900 is a sweet deal for Rigol though. $200 higher sticker price could maybe make them three times the profit, all for the cost of a $1 edge connector.
(I think this is the reason they so massively underrate the official bandwidth of the DHO800)

Yep. The DHO804 is amazing value.

I wouldn't have the "problem" with the Rigol, of course.
But then I wouldn't have a bode plot either. ;)
This is a good opportunity to buy yourself a nice generator.
And Rigol could of course also implement Bodeplot and then design it so that you can use external (Rigol) generators for it.
But I don't think that will ever happen.
That's just a point for me, if you don't need a Bodeplot, you can live very well with the 800.

Was the Siglent Bode plot 100% perfect on launch? :popcorn:
(I'm still waiting for an explanation of the Siglent's FFT problems shown in Dave's review of the DHO800...)
