I am looking for some guidance on what is an acceptable signal strength at the input of a integrated digital television (iDTV)/DTT receiver, Freeview HD receiver or Freeview HD digital television recorder (DTR)/personal video recorder (PVR). I presume the two most important measurements of a DTT signal are strength and quality, ie, bit error rate (BER).
In an analog system, such as the free to air VHF and UHF signals that we have all used in the past, the two most important radio frequency measurements have been signal strength (dbµV) and carrier to noise ratio (C/N). A signal strength of 70dbµV and C/N in excess of 43 dB would be considered quite acceptable.
What are the comparable signal strength and bit error rate reqirements/standards for New Zealand's DTT/Freeview signals? I would appreciate it if someone could point me to a reference or source for this information.
Once I know what I need I come to the equipment limitations I face. I have a TV signal strength meter and an HP spectrum analyzer both capable of making VHF and UHF signal strength measurements (dbµV). They are both reasonably accurate and in agreement in making measurements on analog TV signals. What should I expect when I use them to measure a DTT signal?
I will be making the measurements on the MATV system that serves the apartment building where I live. I do not have a Freeview HD receiver or equipment capable of measuring BER on a digital signal. Your help in guiding me in how to use the equipment I have is very much appreciated.
