This brings the total price up to at least 710 USD (with a tablet device) or 460 USD (without a tablet device), which confirms that the real bench oscilloscope option is cheaper if you need 4 channels in total (400 USD). You would need to buy 2 SmartScopes to get 4 channels in total (2x 230 USD), and you still need to add the price of a tablet device next to the SmartScope (add an extra 250-500 USD). 2 - Real bench oscilloscope is cheaper and better: You can get a full-blown 4-channel bench oscilloscope for only 170 USD more (400 USD).

It should be said that if you buy 2 SmartScopes to have 4 channels, you end up spending more money than if you would buy a Rigol DS1054Z oscilloscope up front, which has a much higher bandwidth, a much higher sample rate, a bigger memory, a much higher waveform update rate, and multiple intensity grading levels! = Taking into account all of the above, I fail to understand where to position the SmartScope = 1 - Established players on the market: There are already, for many years, well-established players in the cheap USB scope segment, such as Owon, Hantek, and more recently SainSmart, that offer USB scopes, which are much cheaper (factor 2-3), which have better specs, and that come with much more advanced software (factor 5-10) such as automotive test software, etc. It is very hard, and almost impossible, to beat the Rigol oscilloscope.
8 - Rigol is the Chinese Toyota of oscilloscopes: The Rigol DS1054Z is the "most bang for buck" digital storage bench oscilloscope on the market today.
Even in future software versions, there is no way, that the SmartScope is ever going to reach a decent waveform update rate on the tablet device (impossible without dedicated hardware), and any decent intensity grading implementation, will likely eat up too much CPU, and will further slow down the software. There is no intensity grading at all in the SmartScope (0 levels), while the industry standard is at least 64 intensity grading levels these days. The waveform update rate is limited to 200 waveforms/s, while the industry standard is at least 30.000 waveforms/s these days. 6 - Multiple signals without math options: In the current software version you can combine several SmartScopes together for visualizing multiple signals, but what is the point of that, if the only math function that is available is A+B? Please enlighten me on this! 7 - Some features are below today's expectations or are simply missing: We have not talked yet about waveform update rate and intensity grading. really? This is very low in comparison with the Rigol DS1054Z oscilloscope, which comes with over 16 math functions. Who wants to sacrifice the warranty on a premium high-end device in order to use a low-end device? 5 - The math functions are very limited: The only math function that is available is: A+B.
#Sainsmart dds140 pro how to
Not all people (typical Apple users) will know how to do this, and even if they know how to do it, many people want to keep their tablet device in the factory configuration, to avoid that the warranty is voided. 4 - Tricky installation: Apparently iOS support only works after a jail-break of your Apple tablet device. According to some users, the software freezes and crashes randomly, and the performance is very slow in some measurement scenarios. 3 - Stability and performance issues in the SmartScope: Several people have reported stability and performance issues. But why on Earth, would you want that students and electronic hobbyists leave the comfort of a real bench oscilloscope, and make their experience limited to a touch-screen interface, that is not used anywhere in the industry up to today.
2 - Bad learning experience for target group: LabNation says that their focus is students and electronic hobbyists.
My impression is that there is a disconnect between the assumptions from LabNation and the actual preferences and expectations from end users, industry, schools and universities. But on what basis? A touch-screen interface is nice to have for media, or for navigation, but it will never replace the nice controls on a digital storage bench oscilloscope. = 1 - Real value of a touch-screen interface: LabNation keeps saying that the touch-screen experience is so unique and so much better. = Hereby, a separate thread about the SmartScope from LabNation, to share my thoughts about this device, and to hear feedback from other people.
