The Tektronix MDO4054 is a mixed-domain oscilloscope that integrates analog, digital, and RF signal acquisition into a single instrument. It enables time-correlated measurement across multiple domains, allowing engineers to visualize signal interactions and system behavior simultaneously. The MDO4054 combines four analog channels with 500 MHz bandwidth, 16 digital channels with high-speed acquisition, and a dedicated RF spectrum analyzer extending to 6 GHz. This architecture supports comprehensive debugging and verification of complex embedded systems by correlating events across time and frequency domains.
