SainSmart DSO203 MINI Kit, 72MHz, 4-CH, STM32 Metal shell *NEWEST VERSION* Review
Overview
The oscilloscope easily suffice common electronic engineering tasks. It's basedon ARM cortex M3 (STM32VCT6), providing 72Mhz analog bandwidth with integratedFPGA and high speed ADC. Internal 2MB USB disk could be used to store waveform,user application and upgrade firmware. This is the newest version with thesoftware upgraded to lib 2.25 app2.6
This pocket oscilloscope is largely employed for programs inside followingcircumstances:
1. Repair popular electronic devices outside (Air conditioning or Industrialfrequency inverter power supply, AC / DC switching electrical power supply orinverter, elevator and constructing fire safety products, industrial controlcircuit)
2. Hardware preservation or software program debugging RS232, RS485, I2C, CANalong with other communications interface circuits, LED show and keyboard scandriver circuit, brushless motor drive circuit
3. Audio devices and circuits, electronic toys and remote handle designs, car ortruck repair electronic circuits
4. College after-school teaching practice and college student advancement ofelectronic modest manufacturing
5. Should sluggish signal adjustments observed applications (such as: relay andchange contacts jitter, battery cost and discharge curves on the load transientresponse strength provide, temperature sensor attributes measurement)
6. The relevant provide electronic circuit (SCR voltage regulator, strengthcomponent correction, electronic vitality saving lamps, dysprosium lamp mercurylamp sodium lamp xenon lights drive circuit), As for other problems this sort ofas: CPU clock, RAM entry, bus and USB or Ethernet signal measurement, highfrequency plus the video circuitry plus the must use FFT for signal analysis andso on event.

Better than the other DSO 203's out there
By R. Vernon
This is the latest hardware and software rev of the DSO 203 as of 9/8/2012. It's WAYYY better than the V2.6. Nice screwed down battery compartment. Battery pre-installed. Feels better in your hands. Looking forward to the CHIP firmware. It's a decent micro-portable o-scope for doing things like ESR measurement (nice built in signal generator). Great for doing circuit tracing. I only had to build a small experiment box to get the octopus circuit up and running. You can buy MCX male to BNC/Coax/SMC pigtail cables to do all kinds of things including using your old attenuators. It's really not bad. Menu navigation takes about 10-20 minutes to learn. Don't get frustrated and just practice and you will get the hang of it in no time. Keep in mind the menu nav had to be really tight due to the lack of navigation buttons and screen real estate. I think a touch screen would be the only thing I would add. Being able to drag the trigger/ time-delta/ voltage-delta markers would have been nice.
OH, and go to EBAY to grab 3 MCX to micro clip pig tails for C,D and sig-gen out.

Very disappointed
By HD Rider
First of all, I have to say as an electrical engineer and a tech geek, I was like a kid in a candy store waiting for this to arrive. And when it did, I was excited to get it up and running. The build quality is excellent and looked like this was going to fit into my portable lab equipment quite nicely. But then, I tried to calibrate it. The included instructions are horrible, so I went online to check the calibration procedure. I followed it to the letter at least a half a dozen times. But it would never change the results. I then checked other websites and confirmed that the calibration steps that I was using were correct. But every time I tried to save the calibration, the unit would just get stuck in a calibrate loop. I gave it to an engineering buddy and he tried to calibrate it and got the same results. No parameters would ever change and the voltage reading were off by about 20% on every scale. So four hours of trying every possible technique to update the calibration were fruitless. It's a huge disappointment, because everything else about the unit was great, and even fun to play with. But if the voltage readings aren't accurate, its just useless to me. So back she goes. My quest for a little o-scope continues........

Returned in one day
By Mark Twain
I had this for less than one day and decided it just wasn't appropriate for any realistic testing I would do with it. The calibration changes depending on if you're running on batteries or the charger, the connectors are non-standard as far as test equipment goes, and the controls are too hard to use when you're trying to get something done.
I ordered an OWON benchtop 'scope and have been very happy with it.
