The Tektronix MDO4104-6 is a mixed-domain oscilloscope that integrates spectrum analysis with time-domain capture, enabling simultaneous acquisition and analysis of analog, digital, and RF signals in a single instrument. This architecture eliminates the need for separate test equipment and provides time-correlated visibility across frequency and time domains, critical for debugging complex designs where RF behavior intersects with digital logic and analog circuits.
