Key facts

  • High-performance spectrum monitoring from 8 kHz to 40 GHz (with options)
  • Accurate AOA direction finding from 300 kHz to 8.2 GHz (with options)
  • Reliable detection of weak signals in dense spectrum environments
  • Cutting-edge signal measurements in the frequency and time domain (option)
  • Performance and device testing in line with ITU Recommendations

Premium-class signal reception and analysis

The R&S®ESMD wideband monitoring receiver was specially developed for signal search, radiomonitoring, radio detection and spectrum monitoring tasks. It performs ITU-compliant measurements and meets the requirements of security authorities and organizations. The receiver is ideal for both stationary and mobile/vehicular applications because it can be operated via the front panel or remotely controlled via LAN.

Features & benefits

Superior RF performance in dense spectrum environments

The R&S®ESMD provides an optimal trade-off between linearity and sensitivity and can reliably detect weak signals among strong unwanted signals in a crowded spectrum. This is achieved by extensive preselection filtering including filterbanks and tunable bandpass filters over the entire frequency range to protect against intermodulation from strong out-of-band signals.

ITU-compliant measurements

The performance of R&S®ESMD is in line with all respective recommendations from the ITU-R. The optional R&S®ESMD-IM option allows for ITU-compliant measurements of signal parameters such as bandwidth, center frequency and modulation depth.


Cutting-edge signal measurements

The R&S®ESMD features a comprehensive tool set for any kind of signal measurements:

  • Parallel time and frequency analysis in zero span mode
  • Polychrome spectrum for the detection of superimposed pulsed signals
  • Trace recording and replay
  • Automatic record and replay of I/Q data with various trigger conditions 
  • Parallel multichannel signal analysis and detection with R&S®CA120

Direction finding and radiolocation

The R&S®ESMD forms the basis of a precise direction finding or radiolocation system:

  • Accurate angle-of arrival (AOA) direction finding with R&S®ADDx single channel DF antennas
  • Mapping functions with automatic triangulation
  • AOA DF error correction
  • Support of TDOA with internal GNSS module
