Channel Measurement Equipment (CME) DT4200

Professional Channel Measurement Equipment for easy drive testing with up to 6 antennas

The channel measurement equipment (CME) is a test receiver designed for easy drive testing with simultaneous measuring of up to 6 antenna signals. The antennas and their frequency bands can be chosen according to customer requirements. The CME supports the entire frequency range from VHF to S-band.

Features:

  • Stand-alone unit comprising DT4200 PC Unit and Antenna Assembly
  • Simultaneous handling of up to 6 antenna signals
  •  Each of the 6 RF inputs has a high analog bandwidth of 34.67 MHz; supporting center frequencies from VHF to S-Band
  • Power is measured in bandwidths of 542 kHz, with the number of available power level detectors (16 to 64) depending on the number of simultaneously measured antennas
  • Power level measurement rate is 2.116 kHz (for each of the up to 64 Sub-Bands)
  • Snapshot recording of baseband I/Q data (single antenna bandwidth up to 34.67 MHz, multi-antenna bandwidth up to 52 MHz) to hard disk for further analysis, e. g Channel Impulse Response (CIR) 
  • Connectivity for GPS Receiver
  • High reliability hardware built for continuous operation
  • Comfortable realtime GUI
  • In-the-field GUI for easy data verification and initial analysis during trials
  • Detailed post-processing tool chain for advanced signal analysis
  •  Remote GUI software allowing full control of the CME via secure web access through the internet 
  • 12 V powered equipment

Applications:

The channel measurement equipment (CME) is a flexible test receiver designed for multiple applications in the context of statistical analysis of the QoS and coverage of satellite and terrestrial communication systems like:

  • Analysis of the QoS for mobile satellite systems (e.g. DVB-SH, ESDR, SDARS, future broadband systems)
  • Verification of the coverage of terrestrial repeaters
  •  Analysis of antenna subsystems in the field (e.g. antenna diversity gain, comparison of different antennas)

The CME includes 6 antenna inputs. If more antennas are required, several CME units can be used in parallel. The measurement bandwidth of a single antenna is up to 35 MHz, which is split into up to 64 sub bands to measure several carriers in parallel or to allow the analysis of frequency selective fading.

The standard version of CME supports the VHF, UHF, L-Band and S-Band. The modular approach allows a customisation to different frequency bands.

The CME supports 3 operation modes:

  • Power level measurement mode
  • CW mode
  • Snapshot recording mode
