Best oscilloscope for beginer

(1/5) > >>

khatus:
Hello i am an electronics enthusiast.My subject of  interests is micro controller,FPGA and Power electronics.Since i am a beginner,I don't want to spend too much for oscilloscope i.e looking for a cheap one.While searching in the internet many suggests Siglent SDS1102CML and RIGOL DS1074Z are best for beginner.
But i get confused which should i buy siglent or rigol??If there are any good cheap oscilloscope then also suggest those names

Howardlong:
You will get a ton of different answers, but my first thought bearing in mind your applications is that two channels will be a frustration. While I don’t always use more than two channels, it’s far from an uncommon scenario to use three or four.

The DS1054Z is four channel and can be coerced into 100MHz bandwidth, and all the options enabled. I don’t have experience of the Siglent so I can’t comment on it in comparison.

human dont always use more than two hands, just because they are the only two given to human. if human are given with 4 hands, they will happily use all of them, and they will say... I don’t always use more than four hands.

jazper:
I say get a siglent 1104-xe if you can afford it. Better hardware than the rigol, more features, 4 channels and an easier interface than the rigol.

If you can't afford it, consider getting a few extra multimeters

tggzzz:
Firstly, decide what bandwidth you need. For "digital" signals[1], completely ignore your signal's frequency (i.e. it doesn't matter if it is 10MHz or 10Hz), concentrate on your signal's risetime and falltime, and use BW=0.35/t.

Secondly, decide how many channels you need to observe simultaneously.

Thirdly, if those channels are "digital", consider using a cheap logic analyser to observe them.

[1] I use the term loosely, unless you are considering photon counting or femtoamp circuits. In other cases the signals are actually analogue signals, which are interpreted by the receiver as digital signals. Use a scope to ensure those analogue signals will be correctly interpreted as digital signals - i.e. signal integrity. Then flip to using digital tools, especially logic analysers and printf statements.
