buy a better oscilloscope than the Siglent SDS1104X-E
uargo:
ok thanks everyone, I think the question then would be:
SDS2104X PLUS or SDS1104X HD?
I am designing an antenna rotor controller and I need to reduce the noise from the power supply and the reference voltage for the ADC readings. I need a fairly accurate oscilloscope to see the noise at 600uV or less
Martin72:
So the MSO5074 from rigol will be definitely out of the game... ;D

The MSO5074 is currently 810 pounds + VAT in the UK. The SDS2104X+ is 1050 pounds + VAT. If you can afford the higher price you get a better instrument. The market seems to be functioning properly.
uargo:
but why do I want to buy the Rigol MSO5074 if it doesn't work for me later. The question is whether the Siglent SDS2104X PLUS will suffice, or better the Siglent SDS1000X HD or the Rigol HDO1000X HD.
Can someone who has these oscilloscopes advise me?

But what does "better" mean in this context?
You need to provide more detail of work to be performed to get more targeted advice.
Maybe you don't need a "better" scope at all?
What is a type of work you could not do that prompted you to want a "better" scope. Start with that.
Siglent SDS2104X Plus is a 500 MHz scope platform. Low noise, good for both high BW and small signals. MSO. Very good BODE plot.
Rigol MSO5000 is 350Mhz design without 50Ω inputs. It has 2 Ch AWG, 4 decodes. Higher noise and lower sensitivity. It is good for general purpose work, not ideal for fine analog work. For Arduino kind of work decent choice.
Both Siglent and Rigol 1000HD platforms are low BW, up to 200 MHz, so same as SDS1104X-E. They would be very good for fine analog work, but with BW limit.
So as @coppice already said, Siglent SDS2104X Plus is best compromise of all listed, with limited other info...
Even very expensive scopes will never be perfect for "everything". They all specialize something: BW, noise, math, screen size, decoding...That is why people end up with many scopes...
