The DS211 is a pocket-sized digital storage oscilloscope designed to meet basic electronic engineering requirements. It is an updated version of the DSO201 and features a 2.8-inch color TFT LCD display with a resolution of 320×240 pixels. The device is incredibly lightweight, weighing only 65g, making it highly portable and ideal for fieldwork or DIY projects.

The DS211 is equipped with an STM32F103VC MCU and an internal ADC, and it comes with one analog channel and one internal channel. The device has an analog bandwidth of 200kHz and a maximum sampling rate of 1MSa/s, with a maximum memory depth of 8k. The horizontal scanning speed can be adjusted between 1µs/Div and 2s/Div in a 1-2-5 sequence step, and the vertical sensitivity can be adjusted between 20mV/Div and 10V/Div in the same sequence step.

The device has a DC/AC coupling option and can operate in ascending or descending edge trigger mode. It also comes with an AUTO_FIT mode for automatic adjustment of waveforms. The DS211 has three waveforms options: -A, RecA, and A + RecA. It also provides signal output options including square wave, sine wave, triangle wave, and sawtooth.

The DS211 has a built-in 8MB U disk for storage, and it supports trigger modes such as Auto, Normal, Single, None, and Scan. The device features automatic measurements of frequency, cycle, duty, Vpp, Vram, Vavg, and DC voltage. It also has precise vertical and horizontal measurement options with markers, as well as a rising/falling edge trigger with adjustable trig level and sensitivity. The device also has a hold/run feature for easy waveform analysis. Overall, the DS211 is a versatile and portable device that can be used for a range of electronic engineering applications.
