Free PC Oscilloscope Software Preferences ?

Nov 30, 2006 16 Replies

I am looking for a free oscilloscope program for the PC to run under Windows XP. Does anyone have any preferences ? It needs to be quasi-real....not just a toy, but it can be very simple. I have no need for spectrum analysis and single trace would suffice, but I do need a calibrated timebase, for example. So far what I have found does not meet my needs (time axis won't run slow enough, uncalibrated timebase, doesn't quite work properly on my computer....etc.).

What is bandwidth required? There is good 'winscope' available free for frequencies upto 20Khz.

LOL what? An oscilloscope is hardware, what are you gonna do with software without hardware somewhere? What are you gonna scope with this program???? I mean you can download a free logic analyzer program, but without the hardware what's the use? Here's a free software that lets you control an oscilloscope...

So it's free, and then what??

Bandwidth required is whatever the sound card can provide....so 20 kHz is fine. But the WINSCOPE I have found (by Konstantin Zeldovich) is limited to a 50ms scan time. I want to measure time differences of up to at least 100ms so this is not adequate.

But thanks for your suggestion.

Sound card !

That could be useful in some circumstances....any suggestions as to good ones (that don't use serial ports as it has to run on a modern notebook) ?

Take a look at:

They claim to have sound card support, so it might be worth a look.

You can always use a USB to serial converter.

Bush league amateur stuff! What probe can you use? What can you probe worth a damn with 20Hz-20KHz? Except audio itself?

Get real...

Sure, here's the free program. When you're ready, buy the logic analyzer and stop wasting time with bush league amateur stuff. It's your time to waste, but life is short.

That works very nicely for my current requirement. Hope it doesn't evaporate after 30 days or something !

Thanks, Don.

Sometimes the bush league amateur stuff is all that is needed !

Thanks for the link.

It should not be impossible to get a 100$ FPGA board, generate a VGA display, use a 100MHz flash DC and have 100MHz logic analiser / digital storage scope for little more then that plus the price of the probe and a few discrete components. Like for example here:

Thanks for the link - by sheer co-incidence I was also looking for something like that, and it looks like a good one too.

Visual Analyser is free. Uses your soundcard as a scope, spectrum analyzer, audio signal generator, voltmeter etc. Scope has zoom, trigger, calibrate, screen capture and more.

OK But good enough for me.

Yes...that one looks pretty good for my needs too. Thanks.
