Can't see on youre picture if you are using AC_RMS Measuring is this normal on Siglent???

So Youre Measured Values are a lot Better than on the Datasheet, you lucky Dude ;)

All good, it's not meant to be a competition. I just wanted to point out that, while the time base accuracy of the DHO1000 is exceptional for its class, the noise is par for the course. Which is still pretty good, and certainly a major improvement over any typical 8-bit scope.  :-+

The display is clearly another DHO1000 strength. I had a DHO1000 in December/January, and while am still happy with my decision to switch to the Siglent, I would not mind getting the larger, high-res screen back!

Siglent uses the term "StdDev" for what Rigol calls "AC.RMS". One company using mathematical terminology, one the EE term, but both mean the same thing. My screenshots show standard deviation measured in all four channels. In addition I have enabled statistics, so you best look at the "Mean" line, which shows the StdDev averaged over many sweeps for a more stable readout.

It indeed seems that either Siglent was very conservative in specifying the noise floor, or I have a better-than-average unit. I just checked the single-channel noise at 500 µV/div and 100 µs/div and get just below 50 µV (rms or std. deviation value). And my scope still thinks it's an SDS824X HD. Not sure what's going on, but I won't complain...

Hi,

sure not an Compilation, but i always like to see how other Scopes perform in Comparsion to his Datasheets.

Also would realy like to see this kind of stuff from the SDS1000X HD Series in Comparsion.

Also better on Siglent is the FFT i guess he using 2Mpoints instead of 1MPoints on Rigol, right?

For That i am using the QA403 for Audio and the TinySA Ultra for Higher RF Values.
May be any day, if i got lots of Money (Dreaming ;) LOL) an Spektrumanalysator in Kombination with an VNA would be nice Toy but they are so damm expensive :(
To Expensive for Hobby Purpose.

The SDS1000X HD is quite similar to the 800X HD, the larger screen (but with the same resolution) being the most obvious difference. Performance data are exactly the same as for the 824X HD, if I have not overlooked anything, and the internal architecture is the same. But there are a few additional features, notably including 50 Ohm inputs.

It's not so much the larger number of data points, but the more thoughtful software implementation, I'd say. E.g. you get Averaging and Peak Hold modes for the FFT, which Rigol does not offer. In general, the maturity of the software was what tipped the scale in favor of the SDS800X HD for me.

But this is drifting off-topic. If you want to learn more about the Siglent's capabilities, there is a great in-depth review & demonstration thread by forum member Performa01.

A picture of my DHO ;D ;D :-DD
50Ohm

Seems to be broken.  :P
