Hello everybody,

Well with getting back into trying various electronic project all of which at some point in time or another need an oscope and with teslacoil work, and the fact that my old 1ch oscope died finally, I was thinking of getting a new and since ebay is great for finding "gems in the rough" so to speak I noticed this oscope for sale

and was wondering what some of the wiser folks around here thought of owon and wether or not this was is a good oscope?

Okay, firstly what do you plan on using the scope for? Do you want to see a ringdown or are you doing analysis work?

I must say its a real steal because I paid twice that for my BK scope 12 years ago! That's how much things have progressed. But the question is still how much of a workhorse do you need? Do you need one that will do FFT and talk to your computer, and save to disk? Are you looking to generate a report of your work?

I'm just looking for a scope thats ligh and portable with 2ch. I'd like to use for anaylising waveforms, say from the interuptor to the primary and compare, being able to upload to the pc is just a bonus, otherwise most of the other small ones were eitehr 2x the price or pco and I didn't want to always be tied down to a pc. Checking for ringdown would be a use for it.

Also what is FFT?

The big thing I was concerned about was is it a good or decent company, is it a deal or houl I wait to see if a cheaper one comes up?

FFT is fast Fourier Transform. That allows you to see the spectral density (power ) distribution of a waveform, its basically the math equalivent of a spectrum analyzer, so you have a scope and analyzer deal package, or 2 for the price of 1.

My opinion is that $350 for a portable scope is a real bargain, but you will need to consider a few details when it comes to PC interfacing and recalling waveforms. If the scope is GPIB only, that presents some problems in recalling waveforms, a detail I'm getting more familiar with. If it has a serial connection, or USB, you're pretty well set for life.

25MHz is more then enough of a scope if you're sticking to TC's alone. But if you want to do radio work, or HF, VHF or UHF, then you're going to need a more capable instrument.

I think my first scope was 10MHz Analog and it was more then enough to handle looking at waveforms, but again, what you plan on doing determines what you need.

You can always get a scope for TC stuff now, and get a scope with more bandwidth later too, so that's the other side of the coin. What you want to do and how soon.

I have had excellent luck with the OWONEDU5022, although I will warn you that the adc's in it aren't all that great and there the 5mv/div setting is all but useless because there is so much background noise on it. Also the USB transfer software seems a little flaky, but worse comes to worse a factory reset in the scope always fixes those problems.

I will vouch that its inputs are quite well protected, I accidentally pulled a 3" flame off my sstc to one of my probes and aside from meting the probe a bit the scope was fine

Awsome thanks guys for the valued information, I had kinda bought a Differnet owon scope b4 posting but it seems I made the good choice anyways, and hazzmatt "..." said it for me it comes with a usb to pc interface. Thanks again guys for the valued input.

Sounds real good! Hope to see some waveforms soon! ^^

As my first scope I'm looking at a http://us.fluke.com/usen/products/specifications.htm?cs_id=1982(FlukeProducts)&category=OBS(FlukeProducts) . I think this will work for any testing for the miniBrute build. Any opinions?
