O'Scope

Hello All,

It's 2013 and this time for sure within the next 2 wks or so I will purchase an O'scope. From Nuts & Volts Oct. 2012 I'm sort of stuck on the www.Saelig.com (DS1102E 100 MHz 2-Channel). Cost is listed at $400.00/Free shipping. I have one(1) dead BS2 stamp and my own OEM acting up, so it's time. Some day I'll move up to the Propeller but for now it's the BS2e/40 series.

Has any one used this family of products or read any other reviews? I never trust their own on-line testimonials.

I can make the space on my desk and would rather have a stand alone unit.

I did read some comments on Scopes on the Forum here.

Thanks

    See http://forums.parallax.com/showthread.php/146355-Analog-Discovery-Kit if you can use a USB scope. Looks like the $99 price is still good.

    You might want to look at the +$30 option, of SDS7102 100MHz 1GS/s 10Mpt 2-Ch Oscilloscope - larger screen, more pixels, and 10X the Memory depth.

    I think some of the better scopes also include Frequency Counters - fits in the corner of a FPGA, so no excuse for not doing this, from the trigger signal. ( found one : the UTD2102CEL - 6 digit counter, memory depth is less than the 10Mpt one tho )

    If you haven't already, you might want to check out the EEVblog forums. It's an all around good forum for electronics and there's a lot of discussion threads about what equipment to buy. Many of the EEVblog videos deal with oscilloscopes.

    Hello RDL2004,

    I did check out that Forum and WOW. They had lots of insight into that scope and all it's features. There seems to be a real problem with measurements @ or below 0.5 vdc, and having noise on one or both channels. Owon is on it's Chinese Holiday(month), so as there appears to be some insight to the fix(from Hacks), it has not been implemented into the current production line nor (PCB). One guy appears to have started a blogg over a year ago on this product and its been going strong up til even a few days ago(Lots of info). So I'm kind of stuck for now and will look around some more and wait for some more feed back on this Forum also.

    Thanks

    If you've never owned or used an oscilloscope before, I would actually recommend getting one of the cheaper PC based devices. After you've used one of these for a while you'll have a much better idea of what you really need and are willing to pay for. The Analog Discovery Kit would have been a great one to start with since it has several other capabilities besides the oscilloscope, but it looks like the $99 special deal has ended. You could always try to find one (or something similar) on eBay.

    I do agree with your preference of having a real, stand-alone instrument instead of a PC based device. I have a Tektronix 2247A I bought used on eBay quite some time ago, but it's a hulking monster. I bought a Rigol DS1052E a couple of years ago. It fits nicely on the bench top and has pretty much done everything I need a scope to do.

    Hello RDL2004,

    It's been a while, but 6 yrs AF and 5 yrs Private company. I did buy a pc base one from Parallax but I think that I returned it. I looked around and could not find it. Any way, I'm waiting to see what they say about the SDS7102 100MHz and it's ground issue. Maybe I can find something else in that range. I'm mainly going to be working on my own OEM's and Parallax MC. I'll read up on the DS1052E.

    Thanks for the feed back

    Hello All,
    Well I finally laid down the money for the Rigol 2102 yesterday, it should be here next Wed. or Thur. The 2072 will not be available til mid to late Aug. and that was from 3 places I cked. I got a deal and free shipping for $1075.00. I so badly wanted to get the Owon 7102 at ($300 or $400) but the reviews were not good and the 2 yr. blog seem to go UN-answered from the Company. If Owon just implement some of the offered fixes maybe their reviews would change(but maybe they are making enough money and don't care). Second try was the GW-Instek 2102A, this also seems like a great pick but memory depth and not so hot review on YouTube. nix that one. The third was the Rigol and its tear down was very good. The operation of the unit seem to be excellent. So its a done deal. As stated before this will be my first usage of a DSO and it been 15 yr. since I last used one.
    So now its do I want to get a Signal Generator or not? ($350-$550) range. I'm not total sure though, not much more.

    Thanks again for leading me to the EEBlog site.
