The DHO4204 Digital High-Resolution Oscilloscope provides improved signal integrity and value with our latest oscilloscope technology. Our UltraVision III platform combined with a new ASIC chip design that provides true 12-bit samples makes the DHO4204 a great for high speed, high signal fidelity applications. With 200 MHz of bandwidth and 4 channels, these oscilloscopes have our best signal visualization capabilities and a bandwidth limited typical specification of just 18 μVrms AC for an ultra-low noise floor. Combine 250 million points of memory, our new Ultra Acquire burst capture mode, and advanced analysis functions for the best signal fidelity value on the market. The DHO4204 is a powerful entry level solution for engineers looking for next generation signal quality and value. All DHO4000 Series models include standard serial decoding for RS232/UART, I2C, SPI, and CAN busses. They all ship with a 3-year warranty and a passive probe for each channel. Post-sales software upgrades are available for bandwidth, additional serial decoding, and memory depth.
