DekTec Launches DTU-238 RF and ASI Analysis Probe

DekTec adds DTU-238 to their line of USB-2 measurement probes. Connected to a laptop or tablet, the DTU-238 forms a comprehensive solution designed to provide real-time recording, analysis and monitoring of terrestrial, cable and baseband DTV signals.

The DekTec DTU-238 is a portable unit for real-time analysis of terrestrial (DVB-T2/T, ISDB-T) and DVB-C cable signals (DVB-C2 is also supported). An extra DVB-ASI input lets you analyze baseband Transport Streams. The unit is USB powered and does not require a separate power supply.

The following DTV standards are supported:

  • Terrestrial: DVB-T2 including T2-lite, DVB-T and ISDB-T*.
  • Cable: DVB-C2 and DVB-C (QAM-A). DVB-C2 is not used much yet, but the DTU-238 is prepared!
  • Please note that QAM-B and 8VSB is not supported; for those standards the DTU-236A is required.
  • Baseband: DVB-ASI. This allows recording and analysis of baseband Transport Streams.
  • The following software is available for the DTU-238:
  • RFXpert for performing real-time measurements on various RF parameters, including MER, RF level and BER (bit error rate). Spectrum, constellation and eye diagram are displayed in the user interface and can be used to assess the signal quality.
  • StreamXpert is a user-friendly Transport Stream analyzer for showing the detailed contents of the TS and decoding audio, video and data (tables). PCR accuracy can be measured and plotted and TR 101 290 error conditions are detected and logged.
  • For building custom applications, the DTU-238 is fully supported by the free Windows SDK (WinSDK) and Linux SDK.
  • The DTU-238 is shipping now
