Oscilloscope

Kit - 2007-01-25 11:23:00
Hi all, I have finally decided to break down and buy a oscilloscope. But I found I don't know what to get. As this will be by first oscilloscope I don't need any thing fancy. I don't have a lot of money so a used one would be fine, if it had a manual or I could get one. I would be willing to sp...Oscilloscope

Beginning Oscilloscope Question

rpsommers@gmail.com - 2007-05-04 20:30:00
I just received an oscilloscope I bought off eBay. I'm trying to test it but can't seem to get any vertical deflection. I setup a little LED flasher with a 16F88 and put it in INTRC+ClkOut. When I measure the clock frequency with my multimeter I get 62kHz. But I can't get the scope to show any d...Beginning Oscilloscope Question
