Sexiii. I am soon in the market for one. Thoughts on some good ones?

what is that shit even used for

Viewing electrical signals. If your measuring DC, (or just AC amplitude) a multimeter will suffice. For detailed analysis on a signal in and out of a testing circuit, an oscilloscope is highly desirable. (Here's a shitty picture of square wave on the ol' Tek)

I'm not at home so I can't take pictures, but is anyone else part of the Tek 7000 master race?

In the past I'd have told you to beg one off of your local university, but rigols are so cheap it's almost worth buying new.

The usual advice applies regardless: 20Mhz bandwidth/80Msps minimum, 5mV/div - 5V/div amplification range minimum (preferably something that can go down to the tens of microvolts per division), external trigger (if mixed signal then it should be able to trigger off of logic signals too), 1 Megohm input impedance, XY mode, external Z. Any digital scope worth buying has FFT/math modes and storage.

If you buy used make sure you get probes and can find a service/callibration manual for it online, BAMA is a good source of old manuals. A good manual has full schematics, a good scope is worthless without a good manual.

That's pretty sick Anon

why dont u post this shit on sci
theres nobody ITT who takes EE and does it seriously enough to warrant this thread

anyone who says otherwise is lying

>>55661231
I disagree, I also am wanting to get an oscilloscope as I have taken EE as a hobby.

I don't think I could beg my local uni though, what would I even say?

>>55661249
The only time any uni will give you an oscilloscope is when they are clearing house and throwing old shit out.

>>55661269
In my case, my uni is apparently not even allowed to give it - I remember having to bargain and sweet talk someone just to get the right to pick up something that was basically going to get trashed anyway.

lul

When I used to work for GE I copped like 15+ alpine white mech keyboards for free from recycling, not counting fucking working DMMs. You just need to find your way to the recycling and garbage area of an electronics manufacturing facility.
