OT/gloat: I got an oscilloscope!

B.B. · 2005-12-02T19:42:45+00:00

And I have no idea how to use it! It was $15 at a garage sale, so I figured at the very least I'd only waste $15 if it's junk. But it seems to operate. Or, at least it'll come on without smoking. Anyway, came with a power cord and one probe. (1x/10x switchable) There's a small photo of the beast. If I had a camera I'd take a better picture. Skimming google I've yet to find any information in english. Now, here's the thing. I can turn it on, and a blip flashes and shoots off to the left side, but that's all I've managed to get out of it. I tried setting all of the controls like I saw in the photo above, but did not get four flat lines. Just a blank screen. Is it busted or did I miss something obvious? Anyone know some quick and dirty field tests to see if it's functional? The fuse isn't burnt. It does seem to have been dropped at some point in the past. But nothing rattles--I think the handle took the brunt of it. And can someone give me a rundown of typical oscilloscope controls' names? And is there some combination of controls I need to avoid lest I blow myself up? Found some general info at I understand most of my switches and knobs now, but I still have no idea what the "Trig'D" light is supposed to indicate. Also, there are two bare metal terminals labeled "CAL (Vp-p)" 200mV and 1V. All input appreciated.

When I bought my first oscilloscope, I did not even know what an oscilloscope was for. Now a scope is one of my indispensable tools, somewhere along with the drill press.
