Title: Christman present for myself .....NOD!!
Post by: peAk on December 16, 2017, 04:25:40 PM
New Oscilloscope Day!

After building one of those small scope kits, I have really been wanting a bigger/better scope. Not sure how much use it will get but there are definitely some things I really need to calibrate and its tough to do without a proper scope.

I know Jason recently got one of these and seemed happy with it. I also believe I have seen Alan with one as well. Seems to be the gold standard for a hobby scope.

Thank God for youtube tutorials!

That's a great Xmas present.  I would love to have one but I'm afraid they don't have a long enough YouTube video to teach me how to use it.

Nice!  I hope someday to get a nice scope like that.

Very nice.  For the handful of times I've needed it my old beater has done me well.  It's about the size of a small amp head but no complaints.

Nice! Mine is a two channel Rigol, I want to get a four channel at some point.

Nice Oscope. I wish I had one but I'd just be playing with the pretty pictures..

That's tits man! My old scope looks like it comes from an old horror flick....

So far I have only scoped the Gristilizer.

I plan to do my Total Recall and Aqua Boy Deluxe, as well my Minimoog.

Took me a while to get over the initial learning curve and get the basics going. Great machine, though. What I really love is how it removes the fog of mystery. Curious how something works or what X will do to Y? just put the scope on it. Though what really tickles me is being able to precisely bias transistors.

Don't know if you have one yet, but you really need a signal generator. I like to use a .1V to .2V peak-to-peak sine wave to stand in for guitar signal.

Glad you just brought that up. I just order a small signal generator kit from Amazon. You think this would be adequate? Or would I need something a little higher end?

I didn't get a kit, I got one of the super cheap FeelTech units. So far I just use it for that sine signal to simulate guitar, so for that I'd say minimum you need something that can do at least 5V peak-to-peak up to 10-15Khz.

What I haven't done with it yet is use it as a stand in for LFO in breadboarding.

simple signal generators will work for almost all audio applications, especially hobbyist stuff. they are useful for calibrating but don't forget you still have to try it with a real instrument after  :P

cool scope! does it do XY mode? does it do fft mode/spectrum mode?

I had to look up XY mode cause I wasn't familiar but yes, it does do X/Y mode as well as FFT. For me, it's a huge learning curve but I am definitely making progress every time I use it.

sweet, being able to see FFT's might be very cool, i highly recommend playing around with that. if you compare the input of a circuit against the output, you can see what kind of harmonics are generated.
