Default Oscilloscope?

For someone who hasn't ever used a scope before and just wants something to play around with, does this seem like a good option?

Everything else seems to start around $300...

Yes it's probably OK.

Things to notice - input impedance is a bit low, I would have thought (check against competitors) so it has the potential to load down sensor outputs (eg oxygen sensor). Also, is only one channel, when in the real world, having two channels is often very useful. Small screen also makes reading it harder.

If you're happy to use a laptop in conjunction, this sort of product is both cheaper and much better.

I have a Siglent SHS-806, but that's six times the budget!

Here's another choice for a basic DSO that has dual input, and a claimed bandwidth of 20 MHz for under $60. It's best to read up on this scope for it's limitations. For instance it has a good bit of internal noise on the display when run at max sensitivity. But for the price it looks OK.

The OEM software that you install on the computer leaves a LOT to be desired and this link takes you to a thread where some programmers have come up with their version of the software / manual etc.

Look at post #540 on this thread for better software

The software will run in demo mode if you install it and run it without having the hardware.
