Mid-range spectrum analyzers gain real-time imaging to show live Rf

摘要

The explosion of digital RF has created a highly complex technology environment, requiring next-generation test and measurement instruments. To address that need, Tektronix Inc. has extended its patented DPX waveform image processor technology to mid-range RSA3000B series real-time spectrum analyzers (RTSAs). Thus, enabling an unprecedented RF signal discovery capability for a broad range of digital RF applications including RFID/NFC, radio communications, and spectrum management. DPX transforms volumes of real-time data and produces a live RF spectrum display that reveals previ-ously unseen RF signals and signal anomalies. As a result, models RSA3300B and RSA3408B are able to provide a unique live RF view, which was not possible with the older models without DPX technology. Digital RF signals carry complex modulation and change from one instant to the next, hopping frequencies, spiking briefly and then disappearing. According to technical marketing manager Darren McCarthy, DPX waveform image-processing capability brings a new level of insight to mid-range RTSAs and permits test engineers to see hidden, intermittent and infrequent signals.
