DSO203 Oscilloscope – Overview

   This digital oscilloscope device can be used for different hobby, professional activities or common electronic engineering tasks. Its management MCU is ARM Cortex-M3 based. Internal USB disk with 8MB size, enables DSO users to store and call different DSO waveforms and raster images to the screen, and also to upgrade the latest available device firmware versions.   

   Hardware design uses a receiving FPGA Integral circuit, manages the control and buffering of data streams to the high quality, 72-MSamples per seconds input ADC. Inside the device is integrated 8M USB disc, suitable for any custom user information – for example to firmware update and to store and call the users waveforms on the screen.

   User information is divided into 4 application related zones, connected with 4 different kinds of firmware application data.
