Radar and EW done right


Verify and validate that radar and electronic warfare systems and subsystems are working as intended, and troubleshoot when they are not. Control analysis from the time domain to get better insights into the frequency domain to ensure proper operation. See and test the smallest details and the larger trends of pulsed signals.


  • Pulse Measurement (Opt 20) characterizes 31 pulse parameters
  • Cumulative statistics on millions of pulses for long term trend analysis
  • Best triggering: find the pulses you need to investigate further
  • Real Time DPX Spectrum and Zero Span help view trends and provide insight

Spectrum Management and Spectrum Monitoring


Unmatched "stare" bandwidth helps detect, classify and locate signals of interest, making the RSA5000 ideal for interference hunting. Detect bursted signals of interest and low signal-to-noise ratio signals other analyzers miss, and rely on long record spectrogram for signal history and frequency mask trigger with alarms aids documentation and unattended monitoring.


  • 165 MHz real time bandwidth with 80 dBc SFDR
  • Swept DPX display finds transient signals across entire 26.5 GHz frequency range
  • Real time DPX spectrogram with over 60,000 traces records hours of high POI spectrum traces
  • Streaming IQ option for 3rd party device long term signal recording

EMI Pre-compliance & Diagnostics


Perform pre-compliance measurements with quasi-peak detector and spurious measurements to quickly asses DUTs and ensure they will pass final EMI compliance testing. If there are failures, use powerful Real Time Spectrum Analysis (RTSA) to understand the mechanism and quickly identify root cause.


  • Spurious measurements with pre saved limits to the FCC, CISPR, ETSI, ANSI standards
  • Faster measurements for high sensitivity: spend less time with spurious measurements due to unique wide band spectrum analysis architecture
  • Quasi-peak detector lets you test the same way the Compliance lab tests
  • Real time displays to visualize and investigate failures: save time by seeing live RF spectrum

RF troubleshooting for the most difficult problems


Discover infrequently occurring signals, trigger on them, capture the signal into memory and analyze the signal fully. Track down problems with the interaction of hardware and software, power supply noise, and other difficult to measure aspects in the RF space.


  • See the signals that other analyzers miss, in real time
  • Save time and gain insight with synchronized frequency, time and modulation displays without switching between modes
