Logic Analyzer - oscilloscope

[epierre]

Hello,

Following my problem on CCD line scan, I was wondering how an oscilloscope could help me.

I have seen that is is possible with an arduino to make something, or use the AD9850 to improve the bandwith as described here and with lxardoscope.

Where I'm not clear is : does that meet my need ? would I need instead ot with it a logic analyzer ?

For the logic analyzer there is

• arduinoscope (software)
• LogicPirate with OLS as software
• Sigrok that connects to hardware such as USB analyzers, and OpenWorkbench Logic Sniffer
• saelae clones or not

Have a look at this one:
Analog discovery

I got one and I am happy with it. Not a pro-tool but I find it sufficient for Arduino/breadboard projects. It combines both analogue scope with logic analysis and signal generator with an arbitrary waveform generator.

Looks like a pretty good multi-device tool.. Any information on it's accuracy?

I ordered and received the following parts to build my own oscilloscope using an Arduino.

I have never used one before so I am learning, and I can always use the arduino and touch screen for other projects like the
Scene Controller [Preview] here.

@lininger This one is impressive ! In fact I restated my search for a logic debugger, for I need to analyse the logic of the clock signal that is more digital than analogic...

I'll go for a saelae clone to see how it works for me to start with, I saw another that seemed good, but it lacks support on its software...

No specifics, but it seem quite enough on breadboard-level development.
But for analog-stuff it will never compete with a proper scope, given the type of interconnects. But to measure noise on power rails and such I find it perfectly adequate.
And the logic part works just fine, analyzing SPI traffic (which is the only test I made so far). The only thing I have noticed is that it seem a bit clunky for analyzing longer digital runs. It does have multiple buffers it uses, but I am yet to learn how to make optimum use of them.

Thanks for the info. I think had I known about it before buying the DSO (Twintex TSO1202), I would have picked this up as the price was exactly the same. (I got a deal on the TSO1202)

@ServiceXp
Well, I am considering a TSO1202 in addition to that one. At some time. Looks at least on visual inspection like good value.
