This is a “5-track, 4-wave line” digital storage oscilloscope for general-purpose electronic engineering tasks and it is based on the ARM Cortex M3 core.

The oscilloscope uses FPGA to manage the external ADC’s control and data cache mode. It provides 4 application partitions for loading and upgrading up to 4 different application firmware. The built-in 8MB USB flash drive allows users to conveniently store waveforms and upgrade the system firmware.

Mini size, lightweight, portable, and handheld; Just about 1/62 of the size of a benchtop oscilloscope; All operations can be done with 4 buttons + 2 encoders.

Up to 100M Sa/s real-time sampling rate instead of the equivalent sampling rate.

4 input channels, 2 digital + 2 analog channels; 1 output channel. Each channel can be freely switched; Supports user-defined outputs like waveform, frequency, duty cycle, etc., suitable for various occasions.

The waveform data can be stored, and the waveform analysis and comparison are more efficient and intuitive; +2% voltage accuracy and +1‰ frequency accuracy; Repeatedly polish the front-end analog circuit to optimize the noise floor to ensure accurate and reliable measurement.

It is suitable for experimental teaching in schools, electronic maintenance, engineering applications, and so on.

Jargon buster

Plain-language definitions for the technical terms used above.

ADC: An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
duty cycle: The fraction of time a signal or light source is switched on during a repeating cycle. On a proximity sensor, changing the duty cycle can affect detection range, response speed, accuracy and power use.
FIFO: FIFO stands for “first in, first out” and is a small memory buffer inside the sensor that stores recent readings in order. This matters because it can help capture motion data without the microcontroller needing to read the sensor every single instant.
