my first oscilloscope Tek 2225
probes are still on order... I don't have a known good function generator right now so I don't have a way to test its calibration, open to suggestions. But for now I'll just start learning how to use it!
Nice scope!
I guess you know you don't have to wait till your probes arrive? For low frequency, audio, etc, you can just use any old wires, with whatever kind of BNC adapter you can find. Any bit of coax with a BNC on one end, any impedance, spliced at the other end to alligator clips. Even plain wires. In the audio to few hundred KHz range, short cable impedance effects can be ignored.
With unshielded wires you'll get a few (tens to hundreds) millivolts of mains hum pickup, but it's all part of the learning experience. Have fun!
Oh, and btw. That scope, like most, has a calibration output. It's the little clip point in the bottom-center of the controls area. You can just wire it directly to the channel BNC inputs for amplitude and sweep calibration, since it is a low fundamental frequency square wave. It's also used for probe edge compensation adjustment, once you get them.
