QAM CONSTELLATION FOR PROLINK-4 PREMIUM

The QAM constellation diagram is now available as an option for the most advanced TV & Satellite Analyser in today’s market, the PROLINK-4 Premium.

The constellation diagram is the result of combining I and Q signals resulting from the QAM digital demodulation. It is very useful to identify some type of problems present in the digital signal which are otherwise difficult to observe.

Some of those problems include noise, phase jitter, compression, IQ level unbalance, presence of interfering signals, etc... Various signal impairments can be seen only on a zoomed constellation display. PROLINK-4 Premium offers that function too.
