Siglent SDS1102CML 100MHz Good beginer scope?
RiRaRi:
Hi! I am newbie and i have never used scope but i would like to learn how to use it in terms of servicing vintage solid state audio equipment. I want to learn how to trace the signal and find "problems". Is this good scope for learning but also for good working in this field? Would you reccomend analog scope for begginers? Price of sigilent is very good i think, about 270EUR
tautech:
We no longer stock them as for 60E more the SDS1202X-E is so much more scope.

While it's always the question, what a "good beginner scope" really is, you said you want to learn. That leaves the question: how much do you want to learn? Of course it is easier to start with a simple instrument that doesn't have many features, hence can be learnt quickly, but on te other hand you might soon outgrow such an instrument and want something better.
You mention servicing vintage audio equipment as the main use case. In the good old times of analog scopes, I would have said that any scope will do, preferably two channels (but not strictly necessary) and bandwidht isn't important - even just 5 MHz will do.
The same is true for digital scopes of course, therefore the SDS1102CML would be more than enough scope for your needs.
On the other hand, modern scopes can do so much more than just show a visual representation of a signal. Nowadays these can be signal analyzers, with tons of automatic measurements, advanced math including FFT and even certain applications like Bode Plot in conjunction with a waveform generator.
So while a simple DSO can do most everything you could with a good old analog scope, you might want to dive into the word of powerful modern DSOs, where you then will have to reconsider many things you have learnt or got used to with the early digital scopes.
My ranking would be (with increasing cost, that is):
* SDS1102CML: does everything you need - for now. It's an older design that might still have some things that were common on analog scopes, but solved differently on modern DSOs.
* SDS1202X-E: is the bottom of the barrel entry level model in the modern DSO world. As a big plus it has a sensitive low noise frontend and it does provide a decent 1 Mpts FFT analysis.
* SDS1104X-E: is 4 channels, which you don't really need; it is similar to the SDS1202X-E, but it has more features and supports Bode Plot in conjunction with an external waveform generator, which can be very handy especially for analysing audio circuits. Think of checking the frequency response of an RIAA equalizer...
* SDS2102X Plus: That is already some luxury model, with big touch screen. It does everything the SDS1000X-E series does, but has two independent math channels, formula editor, better FFT (2 Mpts), 10 bit acquisition mode, more triggers, more measurements, more everything...
* Upcoming budget HD scope: Should come soon, would be similar to the SDS2000X Plus series, but lower max. bandwidth (completely irrelevant for audio) and true 12 bit A/D converters instead. Improves the dynamic range, especially helpful for FFT analysis and also squeezes a few additional dB out of the already huge dynamic range of the Bode Plotter.
radiolistener:
no, it's very old and has too small features. It's better to search SDS-1102X-E. It has a lot of features which are missing in old CML model, and much better graphics and speed.
RiRaRi:
Thanks. Unfortunately i am searching for something cheaper for learning. Also, i have to be aware of the fact that i might blow one up. I mean if something with some good function come up that is little more expensive im in.
Also i heard that a lot of scopes comes with function generator. Is this the case or?
