The Siglent SDS1104X-E is a high-performance, feature-rich 100MHz digital storage oscilloscope designed for professional engineers, educators, and electronics hobbyists. With its four independent channels and a maximum real-time sampling rate of 1 GSa/s, this oscilloscope offers excellent signal fidelity and flexibility for complex circuit analysis. The SDS1104X-E utilizes Siglent’s Super Phosphor Oscilloscope (SPO) technology, delivering enhanced waveform capture rates of up to 100,000 wfms/s, which enables users to visualize transient signals with greater clarity and detail. A large 7-inch TFT-LCD display with 256-level intensity grading and color temperature modes provides an intuitive and visually rich interface for observing signal behavior. The oscilloscope also includes advanced triggering options, including serial bus decoding for I²C, SPI, UART, CAN, and LIN protocols, which is invaluable for embedded system debugging. It supports segmented acquisition (sequence mode), allowing efficient storage and analysis of rare and non-recurring events. USB, LAN, and optional Wi-Fi connectivity offer seamless data transfer and remote operation. With a robust set of math functions, FFT analysis, and a user-friendly interface, the SDS1104X-E combines affordability with capabilities typically found in higher-end instruments. It is an ideal tool for a wide range of applications, from design validation to troubleshooting and education.
