Real-Time Spectrum Analyzer Software for RTSAs, Oscilloscopes, and Logic Analyzers

RSAVu (RSA6000A, RSA3000 Series RTSAs, DSA/DSO70000 Series, and TLA5000/7000 Series)

Offline Analysis Software for RSA6000, RSA3000 Series RTSAs, DSA/DSO70000 Series Oscilloscopes, and TLA5000/7000 Logic Analyzers

RSAVu software enables offline analysis of data captured from Tektronix Real-Time Spectrum Analyzers (RTSAs) and oscilloscopes. The software offers users the same demodulation and analysis capabilities included in the RSA3408B software option suite. From 3G wireless standards to the latest RFID formats and pulsed-signal analysis, RSAVu is a tool designers can use to analyze signals without having acquisition hardware connected. The software supports data files saved on the RSA6106A, RSA6114A, RSA3408A/B, RSA3308A/B and RSA3303A/B Real-Time Spectrum Analyzers and DSA/DSO70000 Series oscilloscopes with option UWB.

When used with the RSA6000 Series RTSA and oscilloscopes, RSAVu can be installed and manually operated directly on the instrument. When used on an external PC, RSAVu supports a remote interface for performing data analysis in automated test environment. Users can programmatically load RSA data files and extract demodulated parameters using their test software to minimize time required for conformance and stress testing.
