An upgrade to SEEED’s single-channel DSO Nano, the DSO Quad v2.6 is a pocket-size oscilloscope with four separate channels and a signal generator for electrical testing and experimentation. Based on an ARM cortex M3 (STM32F103VCT6) 32-bit platform, which provides a 72 MS/s sampling rate with built-in FPGA and high-speed ADC, the device delivers powerful performance in a lightweight and portable package. Its clear 2.5-inch screen and easy-to-navigate buttons make operating the DSO Quad a breeze. With its 2 MB internal USB disk, you can store waveforms, user applications, and upgrade your firmware, too.
