Review of the DSO Nano - Compared to Tektronix Scope

[littlesie]

Hi,I need an oscilloscope to set my audio amplifier gains,to see when the sine wave is squaring off/clipping,would the DSO Nano be okay for that?

[atrepair]

Thank you for the review.

[speedbumphu]

Great review, thanks!

[N1CH0LAS12]

i want to get the version 2 of this to set up audio amps to see if they are clipping. Do u think it would work for tht purpose?

[neptronix]

Thank you for the review. For this price, and for up to ~100kHz, this is a pretty sweet little unit.

SO, the conclusion is: THE DSO NANO IS CRAP,and GET A REAL OSCILLOSCOPE

[gallamine]

@hannobisschoff1 No. The DSO Nano has definite purposes and it is a real oscilloscope. Buy what you need and not more. In most hobbyist cases, the DSO meets those needs. Now quit being rude.

[hannobisschoff1]

@gallamine I seriously was not being rude. I just know that you will LEARN much more with an old (and cheaper) analog oscilloscope, And isn't it all about learning?

[KaldekBoch]

@gallamine Completely agree! I just bought one of these along with a low current probe to monitor waveforms in motorcycle EFI systems for diagnostic purposes. We're talking way under 100khz frequencies here and the DSO nano is perfect for such a task.

[DrBigHappyFun]

It would be great if the camera were focused and not wobbling around.

[gallamine]

@DrBigHappyFun yeah, how dare someone post a free video that doesn't have perfect focus and steadycam! The nerve!

[overunitydotcom]

Why are you not using the right amplitude that fills the whole screen ???

[ms3bani]

try putting the tek in your pocket.

[jpmorgan187]

so whats the point of these nano scopes? who cares? why not just get a rigol, or tek if you can afford it?

[elnod]

@jpmorgan187

Because we can't all afford it?

[gallamine]

@jeclone, Ha! You're right. Unit conversion for dummies :)

[ji553r]

hmm i was just playing with mine and i was able to get the waveform from the amp on screen but i cant "zoom" in on the wave. at first it was almost a straight line then i played with the sensitivety it got a little bigger but it was "flashy" not easily readable

[gallamine]

@ji553r when you say "but i cant "zoom" in on the wave", do you mean zoom in time or in voltage? i.e Are you zooming the x-axis or y-axis? You can zoom by adjusting the time scale. It shows you how many seconds correspond to each block on the x-axis.

[ji553r]

@gallamine yes i think i somewhat figured it out. the XmS/Div is the "time" as you say meaning it can show more waves per block or less waves per block correct. (not too smart so im using lamence terms) and the sensitivety changes how large or small the wave is right? just gotta figure out how to charge it now my battery is dead on it

[thewii552]

@gallamine i think one of his problems is that he has to adjust the trigger...

[ji553r]

reallunacy read my mind i just got mine in and am wanting to use it to check waves off my amplifier. i think my max that i will be outputting is no more than 50 vac will that be too much too handle for the DSO?

[gallamine]

@ji553r @ji553r according to SparkFun's product page, the device has a "80Vpp max input voltage". So, you should be fine.

[Kasatome]

Would this be good for something simple like the pulse output to a HDD motor or would I need a better scope to measure that?

[gallamine]

@Kasatome I'm not familiar with how the HDD motors are driven. After a little searching, it appears they are a three phase motor - akin to a stepper motor. If the HDD is spinning at 5400 RPM, that's 324,000 rev/sec, and with three control lines, each has approximately a 100 kHz signal on it. Based on my experience, the DSO Nano should be able to represent 100 kHz signals pretty well.

YMMV. Let us know how things work out.

[jeclone]

@gallamine a standard hard drive spins at 7200 rpm also the rev per sec would be divided to seconds not multiplied 7200 per minute is 120 per second. but you are right that it is 3 phase and because of that this scope would be poor for that as you can't see the phase angles you could see if all phases are the right pwm but not if they are timed correctly

[reallunacy]

So do think this would be competent to check for clipping in audio applications from around 20-20,000Hz?

[gallamine]

@reallunacy yes, I don't see why not. Provided you aren't dealing with very high voltage signals, it should handle 20-20kHz quite well. The 20 Hz might be a bit difficult, but it has a scan mode that I think would work for that.

nice job.thanks,god example
