Re: Need help getting SDA5000 to read BER

I guess no one bothered to read the whole post. Or their reading comprehension is that of 3rd grader.Are you looking at this in the level measurement summary or next to the constellation display or both? Here's something from the book.Inverted Spectrum and Signal Lock: During the modulation and demodulation of the forward transmission of a digital stream, the spectrum inverts many times - meaning that it flips or mirrors itself, if the SDA does not lock onto a selected QAM channel, the cause may be spectrum inversion. It goes on to say that when you chose your base channel plan NCTA inversion is not anticipated and the default is set to NO.
