SDS7102-V Series SmartDS Deep Memory Digital Storage Oscilloscope with VGA Interface, 2 Channels, 100MHz, 1GS/s Sample Rate

Everything they specify is accurate and functions well. I went through the extensive manual and tested every feature I could and I was very satisfied. If you do the math and the sample rate is enough for your application, this is a great device.I was also surprised to find out that it came with two probes, not just one.

As a stand alone scope, this does everything it advertises. Others commented about the poor manual, but I felt it was adequate. If you know how to use a scope, you can navigate most of the controls without reading the manual. Even advanced operation is menu driven and straight forward. The large display is easy to read and has plenty of room for measurement readings and function button labels. The external USB storage port works easily for transferring images and raw waveform tables to a PC.The software has problems. It is useful for converting the raw waveform files to XLS format and little else. You can capture data directly from a scope connected to a Windows system, but it crashes when I try to use it to alter settings on the scope (the "remote control" function). It pops up a null reference violation message and quits every time I push the "remote control" button.The VGA output works, but produces noisy and wavy video output (on a high quality LCD display) that makes some text hard to read. I don't understand the problem as the main display is crisp, precise and great looking.Good: For the price, it is a capable stand alone scope that meets specification. It is easy to use. All expected hardware was included, and in good shape.Bad: Software does not allow remote control of the scope as advertised. Crashing with a null reference undermines any confidence in its use. VGA output is marginal.Edit: The latest software download does allow remote control. It no longer crashes, but still has a few bugs and hiccups. Some features can be set, some can't, some get set incorrectly. I guess that is progress.

When trying to choose a new scope to replace my older Tektronix Digital Scope I kind of went through the seven hells of frustration trying to figure out which one to buy. At first the choice seemed easy as Rigol seemed to be the rave, but on closer inspection of Rigol scopes I was not that impressed, I think a lot of Fan boy Rigol stuff started up because of the Fact that Agilent used Rigol to make their bottom of line scope model so people expect it to be very good and in some ways Rigols are good scopes.The Owon or Aktakom as it goes by it's USA distributor is IMHO a best value right now because the construction and the features are top notch. Owon in making the SDS8200 series took care of most of the remaining problems in the 7100 series and they upped the capabilities quite a bit.It's Fantastic 8 inch (800x600) HD screen is the best you can get in the sub $1500 level of scopes. The 10M memory depth is unheard of in a sub $3000 scope, no other model has this memory depth, most top out at about 1 or 2MB. The 2GB sampling rate is enormous for a scope in this price range, most are 500MB some are 1GB but 2GB is huge.The construction as I said is top notch, it does not feel like a Chinese product it feels like something made in the USA, the fidelity of the signals it produces is very good, I tried mine up to 400 MHZ and while the signal had dropped about 6db it still had reasonable integrity. Using the 8202 within it's 200Mhz band range it performs like a champ, the triggering is solid, the waveform reproduction is accurate and looks oh so good on that 8" screen.The other great feature of the Owon is that its one of the only full size DSO's that can also be used as a portable, it has a battery compartment under the bottom and uses a single 7.6V 8Amp rechargeable pack (~$59 extra) I highly suggest you get one as you can use the scope for 4 hours on batteries if you need it for field work.The 8200 series and the 7100 series both have FFT built in which is great because the scope can double as a poor mans spectrum analyzer. I own a 1.8Ghz Tektronix Spectrum Analyzer and on comparison to the Owon I found the Owon was surprisingly good at displaying the Main Frequency but not so great on Harmonics.The only negatives I have found so far with the Owon is that the Firmware is not fully developed. Don't get me wrong it does a ton of stuff (Make sure to download the pdf manual and take a look) and all of it works perfectly but Owon has yet to really Tap into this Fantastic screen on the scope. They could use it to do split screen Zoom but they don't. They could add in a number of other menu functions and take better advantage of all the fantastic screen space and the really fine dot pitch they have available. During my research leading up to my purchase I did a lot of reading and found that Owon was resistant to firmware changes claiming that they had no Bugs in their firmware! Recently they did a 180 and are now releasing updates to add new features, this is great news as it means that the current Owon scopes may all be getting more features added.In summary I am impresses, it's a lot of scope for the money and while it may not be as popular as the Rigol it sure beats the crap out of a Rigol 1052 or any of those other Rigols in that sub $1200 price range and that's why I say for right now it's the Best bang for the buck.

Involvement: Expert (understands the inner workings) - Ownership: more than 1 monthPrice: * * * * *Ease of Use: * * * * *Build Quality: * * * * *Usefulness: * * * * *Overall Rating: * * * * *Pros: The bright color high resolution screen is the best of any I've seen no matter what price. The verticle screen resolution is high enough for full display of both 8 bit channels plus timing, amplitude and selection information. 200MHz bandwidth. 2 Giga-Samples/sec. Excellent triggering. 10 Mega-sample record length up to 1 Giga-sample/second. Intuitive functions. Battery life is greater than four hours on aftermarket battery. Internal AC power supply.Cons: It wasn't free but the price was very reasonable.It doesn't come with a battery but an aftermarket battery is easily obtained for less than 60 USD.Other Thoughts: Don't bother with premium shipping. This company sends the product whenever they feel like it. It took two weeks to send out my 3-5 day shipping order after I placed it. I didn't buy from Amazon and this information doesn't apply to Amazon. I have always had extremely prompt service from Amazon.Bottomline: excellent value best screen in class.
