The Real-Time Signal Analyzer-Tektronix RSA5103A replaces conventional instruments, offering the measurement confidence and functionality you demand in everyday tasks.

The RSA5000 Series offers industry-leading real-time specifications and includes the best minimum signal duration for 100% probability of intercept and best real-time dynamic range. With the RSA5000 Series instruments, you get the functionality of a high-performance spectrum analyzer, wideband vector signal analyzer, and the unique trigger-capture-analyze capability of a real-time spectrum analyzer – all in a single package.

Visualize and characterize devices and components with precision and accuracy using the powerful, industry-leading RSA5000B Real Time Spectrum Analyzer. This advanced spectrum analyzer makes high-performance and sensitivity measurements for spurious signals much faster than other spectrum analyzers, so you can conduct conventional measurements and troubleshoot quickly, accurately, and successfully.

Key Features and Benefits
  • Reduce Time-to-Fault and increase design confidence with Real-time Signal Processing
