...The Best DVB-T/H Analysis Tool...

Digital Broadcast Analysis (DBA) Software

Solve your digital broadcast analysis needs

The DBA analysis tool allows the digital broadcast design engineer and network technician to easily add all the required modulation quality and quality of service capabilities to their Tektronix Real-Time and Portable Spectrum Analyzer. The DBA analysis tool combined with the extraordinary spectrum analysis, transient capture, and frequency mask trigger capabilities of the Tektronix RTSA architecture will result in the perfect tool offering all the measurement capabilities required to fully characterize and diagnose any digital broadcast transmitter without requiring any extra tool. The built-in Transport Stream extraction capability along with the Tektronix MTS4SA closes the loop allowing for content analysis and complete cause-effect analysis. DBA offers a set of capabilities needed to characterize digital broadcast signals such as:

  • Modulation analysis: MER (Modulation Error Ratio), MER vs Carrier, MER vs. Carrier vs. Time (MERGram), and selective constellation display.
  • Complete Automatic Spectrum Quality Analysis as defined by the TR101/ETR290 standard.
  • Complete channel response characterization in both time and frequency domains.
  • Full Quality of Service Assessment at the transport layer as per TR101/ETR290 standard.
  • Full TPS analysis and consistency check.


Measurements may be performed over live signals allowing for the interactive measurements environment involved in equipment alignment and adjustments or over recorded data so triggered captures may be analyzed off-line. The DBA software can be run in any Windows based PC but it has been tailored to run right in the target instrument if desired. The display can show up to 4 simultaneous analysis windows and can be easily handled with a mouse and the RTSA embedded keyboard.
