Warning about Counterfeit Products
| Recently, there have been many sellers on sites like Amazon who are selling counterfeit SainSmart products. The counterfeit products look like authentic SainSmart products and they may be advertised under our trademark “SainSmart” or under other brand name. Please note that Sainstore and Amazon.com are currently the only authorized distributors on Amazon for SainSmart products. If you purchase from unauthorized distributors, you risk buying counterfeit products and receiving products and service that don’t meet our standards. We strongly advise that you purchase only from our authorized distributors or directly from us. |
DS203 is a pocket size 4-channel digital storage oscilloscope for common electronic engineering tasks. Its CPU is an ARM Cortex M3, STM32VCT6, with an AD9288-40 dual A/D converter sampling at 72 MHz, and a customer FPGA to manage the ADC and data buffering. A built-in 8MB USB disk enables you to store waveforms and to upgrade firmware. It also provides 4 application areas, convenient for users to load and upgrade at most 4 different application firmware. Schematics and source files are open-sourced to encourage improvements and innovation.

This pocket oscilloscope is largely employed for programs inside following circumstances:
- Repair popular electronic devices outside (Air conditioning or Industrial frequency inverter power supply, AC / DC switching electrical power supply or inverter, elevator and constructing fire safety products, industrial control circuit)
- Hardware preservation or software program debugging RS232, RS485, I2C, CAN along with other communications interface circuits, LED show and keyboard scan driver circuit, brushless motor drive circuit
- Audio devices and circuits, electronic toys and remote handle designs, car or truck repair electronic circuits
- College after-school teaching practice and college student advancement of electronic modest manufacturing
- Should sluggish signal adjustments observed applications (such as: relay and change contacts jitter, battery cost and discharge curves on the load transient response strength provide, temperature sensor attributes measurement)
- The relevant provide electronic circuit (SCR voltage regulator, strength component correction, electronic vitality saving lamps, dysprosium lamp mercury lamp sodium lamp xenon lights drive circuit), As for other problems this sort of as: CPU clock, RAM entry, bus and USB or Ethernet signal measurement, high frequency plus the video circuitry plus the must use FFT for signal analysis and so on event.
