| May 29, 2011 at 0:09 | comment | added | DeVilFisCh | Thanks for the heads up. I'll try looking for that model in the local market. Oscilloscopes tend to be prohibitively expensive on this part of the world so I hope I can find a good deal. I'm also concerned about possible damage on my device's inputs so I'll play safe and acquire an oscilloscope first. Thanks again. | |

It is really great to have access to for this sort of thing. I would err on the side of too much attenuation and work from there. You could easily damage a sensitive input with too much power. | |
