DTT - Digital Terrestrial Television in Portugal: How to monitor the signal for little money...

Today I was looking at the spectrum with the VMA Simple Spectrum Analyser software and satisfaction took over...

Here is a nice measurement of the Portuguese TDT ("Televis√£o Digital Terrestre"):


In one single screen, the following information is automatically measured:

  • Transponder frequency (754MHz)
  • Transponder bandwidth at -6dB (8MHz)
  • Signal to noise ratio (16.4dB)
  • Signal power (62.9dB)
  • Real time spectrum
  • Waterfall diagram
Head on to the download page and try it out yourself!

All you need is an ADF4350/ADF4351 based spectrum analyser, which costs around 60 Euro on eBay.

Cheers,
Vitor
