Re: Portable oscilloscopes
IIRC, Glenn has the Velleman SA-HPS140I and seems to like it a lot...but that Owon does look cool, and the reviews are favorable.
BTW...Amazon has a better price http://www.amazon.com/HDS1021M-Handh...m_sbs_indust_4
Re: Portable oscilloscopes
Thanks Al, yeah I had seen that price on Amazon as well- very nice. I linked the other site since it had actual specs. As for the Velleman HPS140i, check out this price :) http://www.scopemetrics.com/cart/ind...ct_detail&p=10
If it can do what I need, that would be an excellent choice as well. Waiting for some feedback from Glenn since he has used it. It doesn't look like it has DMM features, but at that price, I could always buy a separate DMM if I wanted to.
Re: Portable oscilloscopes
We have the HPS10 in our workshop and that's also a nice device..
Re: Portable oscilloscopes
Thanks!
I ended up ordering with the OWON HDS1021M unit. Very nice specs and a great color tft lcd screen to make viewing much better. It was only $205 on Amazon so tough to pass up.
Re: Portable oscilloscopes
I had this scope http://www.vellemanusa.com/products/...=enu&id=351263
I found that I was as close with a scope as I was by ear so I rarely used it. I usually adjust by ear and then use a DMM and a 60Hz test tone to get the gains as close as possible.
Re: Portable oscilloscopes
Why not the DSO Nano?
Sent from my Springfield XD with love!
Re: Portable oscilloscopes
I wanted good multimeter functions as well in one unit. ;)
BTW, the screen resolution on the OWON makes it much easier to determine a clipping point, not to mention it's just much easier to see/read period (than the TPI). I was just out checking output on the scope to test it and it looks great.

Re: Portable oscilloscopes
And a quick vid of it reading the waveforms of sine waves on a test cd. They change every ten seconds (and i'm playing with time and sensitivity here to get a larger view of the waveform for ease of identifying clipped signal...didn't see any though). Sorry for the motion, trying to adjust scope, hold camera and operate the remote control at the same time- doesn't work well.

Re: Portable oscilloscopes
You might also consider getting one or two of these braking resistors to make a voltage divider for testing amplifier outputs
PS...I ordered the 4-pack that he sells, only to find out that I would have saved $20 by ordering them individually :doh:
