DPX Acquisition Technology for Spectrum Analyzers Fundamentals
Tektronix' patented Digital Phosphor technology or DPX® is used in our Real-Time Spectrum Analyzers (RTSAs), to reveal signal details that are completely missed by conventional spectrum analyzers and vector signal analyzers. The full-motion DPX spectrum's Live RF display shows signals never seen before, giving users instant insight and greatly accelerating discovery and diagnosis. DPX is a standard feature in all Tektronix Real-Time Spectrum Analyzers (RTSAs).
This primer describes the DPX spectrum display and how it addresses situations involving brief, intermittent, complex and/or coincident signals. Also covered are the methods for achieving its key performance specifications.
