NOT to be confused with other cheaper models, the DSO203 is a superb pocket-size 4 channel digital oscilloscope for common electronic engineering tasks and general measuring. It is based on the ARM cortex M3 (STM32VCT6), providing 72MS/s sampling rate with integrated FPGA and high speed ADC. Internal 2MB USB disk could be used to store waveforms, user applications and to upgrade firmware (already upgraded).
This is the BLACK unit.
Features 1) 2 probe connectors 2) 4 inputs & 4 tracks (2 analog 2 digital) 3) A custom waveform output (including the built-in sine, square, triangle) 4) Built-in 2M USB disk 5) Very low power consumption

The item is used - but in perfect condition. Comes complete with cover and both probes, VERY little use. All you need is (mini) USB to charge it up and the internal rechargeable battery keeps it's charge for months. IDEAL for out-on-the-road repairs.
Despite the "used" title this unit has no cosmetic wear, the screen has been protected with a cover and is perfect as is the case. Soft cover included. Hardware v2.7 DSO 1.52 pre-installed and ready to go.
I am ONLY selling this as I have a PC-based scope for use in fixed locations and do not need anticipated mobile use.
