About this deal

The DSO138 is a lightweight, portable training oscilloscope built around an ARM Cortex-M3 processor (STM32F103C8) and a 2.4-inch colour TFT LCD with a 320x240 resolution. Key specs include a 0-200kHz analogue bandwidth, a maximum sampling rate of 1Msps, 12-bit vertical resolution, sensitivity from 10mV/Div to 5V/Div, and a record length of 1,024 points. This kit comes with an assembled case, making it ready to use straight away without needing to source your own enclosure. Designed for both training and development use, the DSO138 has a clear and easy-to-understand design, helping users gain a better understanding of oscilloscopes while ending up with a genuinely useful instrument. It can display frequency, period, pulse width, duty ratio, and peak-to-peak values on screen, and supports automatic, regular, and one-shot trigger modes with rising or falling edge selection, plus a handy HOLD function to freeze the waveform at any time. Source code is available, allowing users to add their own features.
