DS213 oscilloscope standard class lineup: oscilloscope host (built-in lithium battery) = 1, (X1) oscilloscope probe = 1, (X10) oscilloscope probe = 1, warranty card = 1, L-type hexagonal screwdriver = 1, micro-usb charging cable = 1. DS213 is a 5-trace, 4-wire, general-purpose digital storage oscilloscope for electronic engineering tasks based on the ARM Cortex M3 core. DS213 adopts the FPGA's management control of the external ADC and the data caching mode of operation, and provides four application partitions for loading and upgrading the firmware of up to four different applications; and the built-in 8MB USB flash disk for storing the waveforms as well as upgrading the Built-in 8MB USB flash drive for storing waveforms and upgrading system firmware. The oscilloscope code application layer is open source, users can develop oscilloscope firmware according to their needs. Product Features: Small size, light weight, easy to carry, handheld operation; Waveform data can be stored, waveform analysis and comparison is more efficient and intuitive; A variety of triggering methods, support for positive and negative edge triggering, logic triggering, pulse width triggering; Powerful waveform processing capabilities, can automatically measure voltage, frequency, pulse width and other parameters.
