Overview: DS213 is a "5-track 4-wave line" digital storage oscilloscope for general purpose engineering and electronic task based on ARM Cortex M3 core DS213 using FPGA to manage external control of ADC and data cache mode. It provides 4 application partitions to load and update up to 4 different application firmware. It also has an integrated 8 MB USB flash drive to store waveform data and update the system firmware. The oscilloscope code application layer is open source, and users can develop the oscilloscope firmware according to their needs. Features: Compact size, light weight, easy to carry and operate. Waveform data can be stored, and waveform analysis and comparison are more efficient and intuitive. Multiple trigger methods, support positive and negative edge trigger, logic trigger, pulse width trigger. With built-in 8M USB disk, large storage capacity.
