Is Rigol DS1054Z still a good option in 2019?

You feed in a small signal, let's say a sine with 100mVpp, then you press stop and resolve to vertical and post the result.
A DHO800 owner does the same and also posts the result.

Another marketing ploy. No one ever “stretches” a saved (stopped) oscillogram vertically! “Stretching” horizontally is normal, this is why you need more memory.

Vertical Accuracy:
TDS700D - 1% - 8 bit.
DS2000A - 2% - 8 bit.
DS1000Z - 3% - 8 bit.
DHO & HDO - 3% - 12 bit.
It's like making a DMM 6½ characters, but leaving the accuracy at 4½...

Noise comparisons must be made in the same room and on devices with the same frequency band! My device is hacked to 300 MHz.
Limit 100 MHz.
There is no noise in an open field, deep forest or in the middle of the ocean...

At what bandwidth...?
--- End quote ---
≥5 μs/div, up to 500 kHz this is enough.

--- End quote ---
LOL...DHO8-9 IS 12 bit Hi-Res...
That was probably nothing, whatever you wanted to say.

The HDO1000 and HDO4000 have Hi-Res 14 and 16 bits.
DHO800 and DHO900 do not have this!

LOL...
The conversation with you is over...

--- End quote ---
What model did you choose then?
--- Quote from: Martin72 on January 22, 2024, 09:02:02 pm ---There is something like a horizontal time setting, you could use that, every scope has it.
--- End quote ---
This was my theory but wasn't sure if it work same in practice without any hassle and deformation of wave.
--- Quote from: Fungus on January 22, 2024, 08:49:50 pm ---Maybe better to have more detail horizontally.
Whatever: It's obviously the way things are going so you might as well get used to it.
--- End quote ---
Yes you are right, checked many other models and look like this is new standard now.
So I'm considering now DHO904 or wait for bargain on DHO1074 :box:
Unless find another model to confuse me :palm: :-DD :-DD

I bought a DHO1074 during the Black Friday sale: Larger screen overall, and a larger proportion of the vertical space is actually available for trace display. I was really pleased with the display, but ended up returning the scope due to other issues. Waiting for the SDS1000X HD now...
memed:
How much was black friday deal for this model(DHO1074) that time? What problem you had with that oscilloscope?

Not speaking for ebastler, but it was crazy cheap. Like $599 US and I believe the same in Euro. With my eevBlog Saelig discount I think I paid $562 US with shipping but before sales tax. I've since upgraded it to an $1849 US equivalent scope. Crazy deal for <$600.
Yes, it's buggy. There are threads here full of the issues identified. I'm sure I'd be happier with the SDS1000X HD, and depending on its price when released, I may sell my DHO1074 to buy it.
That said, it does indeed have a beautiful screen, and honestly the bugs haven't (yet) hindered my use. But I'm a hobbyist, and not a sophisticated user. So YMMV.
