• Supplied with professional front-end receiver AOR7030
• Uses audio decoder technology provided by CodingTechnologies   

• Continuous monitoring and logging of
  • Field strength
  • Estimated Signal-to-Noise Ratio
  • Audio quality   
• Recording of DRM RF signal
• Recording of defined status signals
• Monitoring output via UDP compliant to ETSI TS 102 349 V1.2.1   

• Inspection of input signal and processed signal at various stages in the decoder. The signal can be displayed in a plot or recorded on a file on hard disk

The graphical display provides different types of plots:

• Time-scrolled plots of a signal (similar to oscilloscope)
• Y plot of single input data
• XY plots of two-dimensional signals (e.g. QAM constellation)
• Spectral view of the signal using FFT
• Histogram plots
• Band-power makers which can be used to calculate the C/N automatically
