Rohde & Schwarz R&S ESMD

The R&S ESMD wideband monitoring receiver

The R&S® ESMD wideband monitoring receiver can handle all the tasks involved in the areas of signal searching, radiomonitoring, radio detection/reconnaissance and spectrum monitoring in line with ITU recommendations. The receiver is equally well suited for mobile and stationary applications. Its operation and functionality are optimized for monitoring tasks. Additional functions allow use in other areas, especially when realtime analysis of signals is required.


  • Frequency range from 9 kHz to 26.5 GHz (basic version: 20 MHz to 3.6 GHz)
  • Extensive preselection for optimum reception even in scenarios with dense signal occupancy
  • 20 MHz realtime bandwidth (optional 80 MHz)
  • Four additional digital down converters (DDCs) within the realtime bandwidth
  • RF spectrum with scan rates of up to 100 GHz/s (300 GHz/s with 80 MHz option)
  • IF spectrum of up to 20 MHz (optional 80 MHz)
  • Polychrome IF spectrum for reliable detection of pulsed signals
  • Video spectrum for displaying the demodulated signal
  • Waterfall display for all spectra
  • Two separate signal processing paths for demodulation/measurements and IF panorama
  • Wideband demodulation for accurate level measurements even for very short pulses
  • Can be expanded into a direction finder
