摘要

Tektronix has just introduced its RSA6100A Series of Real-Time Spectrum Analyzers, targeting digital RF applications. The 6.2-GHz RSA6106A and 14-GHz RSA6114A provide 110-MHz real-time bandwidth simultaneous with 73-dB spurious-free dynamic range, making them well suited to the needs of a broad range of digital RF applications, from power amplifiers for advanced cellular radios to the latest pulsed radar signals. Modern RF signals have become extremely complex, typically employing sophisticated combinations of RF techniques such as bursting, frequency hopping, and adaptive modulation. Triggering on such events - not to mention finding anomalies among them - poses a considerable challenge for test instrument makers. The RSA6100A provides a unique Frequency Mask Trigger (FMT) not found in legacy swept spectrum or vector signal analyzers. The FMT allows the user to trigger a measurement based on the occurrence of a unique pattern of events in the spectrum, including triggering on weak transient signals while ignoring strong known signals.
