Hi folks. First time poster here. I am in the market for my first scope. I've been researching and learning and end up on this forum a lot reading information, so I figured I'd join as it seems a great place to help out....and I'll probably be doing even more reading once I get stuff ordered.
It will primary be used for guitar amplifier repair/building/modding. So it's a pretty simple, straight forward need. I was originally just going to find a used analogue scope but someone pointed out these DSOs and just seemed kind of cool. I like the smaller footprint and fft ability.
I was sent a link to Saelig and the Owon SDS5032EV. I've done some research and have reached that point of saturation. Being a scope newb, there is a LOT of information out there that I feel I'm just swimming in it trying to keep my head afloat. Bandwidth, sample rates, memory, volts/div, the list goes on....and on and on.
I also need a signal generator, and the Hantek 4000 series has one built in, and near as my newbie self can tell, a comparable THD compared to other budget generators that were said to be pretty decent. So this became an option, but there is so little information out there on it. No reviews. I'm not sure anyone has ever bought one and posted about it. lol
http://www.hantek.com/en/ProductDetail_3_4163.htmlOne thing I'm not too fond of is I can't seem to find these at a US supplier. I'd like to buy from a company that I can interface with, and have a little better peace of mind in terms of support.
I'm okay with going another direction and keeping them separate. I had considered this as well with a scope...
http://www.testequipmentdepot.com/instek/signalgenerators/sfg-1013.htmMy needs are simple. If it turns into something beyond a hobby, I will upgrade when the time comes. For now, just keeping it pretty budget minded now, but still decent stuff.
As I said, it's primarily to work on guitar amps. The cheaper Owon has a sample rate of 250MS/s. That in itself is fine in the audio spectrum, but I do worry if that might miss some potential oscillations, though (I really don't know). Also, I want to use the FFT feature (we actually want some harmonic distortion for tone). I know there is some correlation between sample rates and memory for better FFT representation (not that I understand it), and it would make sense that the better sampling of a wave you have, the more precise your FFT would be.....so would the 250Ms/s Owon be adequate for that? Or would a better sample rate lead to better results?
So that's the low down. Just a newb with simple needs looking for a decent setup for now. I'm just looking for any advice, reviews, thoughts, personal feelings to help keep from drowning in the ocean of information to consider.
Thanks!
