Beside the professional solution for RF measurement using the SAM-RX 100 receiver, a more cheaper alternative exists by using commmon USB-2 DVB-T sticks which are based on a DiBcom chipset dib7xxx.

Live Analysis of MPEG-2 Transport Streams
SAMcorder provides two possibilities for the live analysis of MPEG-2 Transport Streams.

  1. SAMbera

    SAMbera performs live DVB Measurement that is oriented on MPEG-2 Measurement Guideline TR 101 290. Because dvbSAM is focused on DVB-H, DVB-H specific enhancements in regard to this guideline have additionally been implemented (Time Slice and Jitter analysis). Call SAMbera from SAMcorder directly. For more information see the SAMbera product page.

  2. SAMalyzer

    SAMcorder creates a snapshot of the MPEG-2 Transport Stream which is currently received and send it to the SAMalyzer application. SAMalyzer performs an in-depth analysis of this transport stream. It extremely simplifies finding problems and errors within DVB-H broadcast services.
    Call SAMalyzer from SAMcorder directly. For more information see the SAMalyzer product page.


Note: SAMbera and SAMalyzer are not part of SAMcorder. Both tools have to be ordered separately.

Scanning and Navigation
  • comfortable scanning a wide frequency range
  • several frequency plans
  • find out and list all DVB-H and DVB-T services
  • comfortable navigation through all services of a channel

DVB-H Playout
  • use SAMcorder to playback a recorded TS
  • SAMcorder supports DekTec DTA 110T, a DVB-H/-T modulator
  • DekTec DTA 110T supports 4k mode
  • create your own DVB-H live signal
  • powerful and cost-efficient solution for testing DVB-H hard- and software components

General Considerations
SAMcorder provides the central input/output processor within dvbSAM suite.

SAMcorder is able to process DVB-H, DVB-T, DVB-S and DVB-S2 transmissions.

SAMcorder does closely interact with other components of the dvbSAM suite, especially with SAMesg, SAMalyzer, SAMitor and SAMflute.
