I'm playing around with some op-amp tutorials, trying to get a grip on how they work. I'd like to build some of them to get a better grip on how they work. I'm on CircuitLab right now since I've got a student license, but I can't seem to find anything resembling an oscilloscope.

For example, I wanted to build a op-amp square wave converter circuit and play around with the resistances and other components right now and watch the response in a scope. What's the best way?

I recommend NI Multisim, its not an online software but it has student version that its very easy to use and you can download for free.

The best thing that I recommend for you its the simulate mode of the program that has a real Tektronix oscilloscope to use. So you can practice the osciloscope handling too.

  • \$\begingroup\$ It's actually pretty clumsy if you've used a real Tek scope. The generic one is better for simulation. \$\endgroup\$ – Matt Young Oct 2 '13 at 21:45
