What Frank is saying is you need an 'S' meter, one that measures actual received signal strength. You can not rely on 'signal quality' meters on satellite receivers because these almost all measure bit error rates (ber) rather than signal strength. There is a relationship between the two but other factors can also influence (...)
Good evening, the price of a DVB-T meter (to analyze digital terrestrial signals) is too high for my pocket :D so I was looking for a complete circuit (a kit) to build it myself. I did not find anything. What I need is an istrument to measure the level, the ber.......all the parameters of the DVB-T signal of a preselected channel, so (...)
Do anyone know if there is a complete and working project to build a DVB-T ber meter (I mean a project with tuner, display , etc) ? Thanks
You need a modulator/signal generator that generates the signal compliant with your receiver. Use PN sequences as data input. As ber meter, you need a dedicated instrument (usually available as signal generator option) or you can acquire your baseband data and make a software post processing (Agilent ADS is well suited). I hope it can help. Mazz
You can not measure receiver sensitivity without modulated signal generator at input signal frequency and level meter to measure signal/noise ratio or ber of output, demodulated signal. Kind of instruments depends on type of modulation you are using.
Look Dallas Semiconductor ber tester chips DS2172 it is very good solution for cheap and simple ber testers from DC up to 52MHz.

Hi, can someone direct me to such a design,or where to start...? thanks.... Bull
