Is there a conversion factor to determine average received power level for an ATSC_8VSB DTV off air signal knowing the level of the pilot carrier or the level of the flat top of the data. Currently on my USB-SA44B I am receiving a pilot of -44.8dBm at 536.31MHz (CH25 DTV) and a flat top data level of about -60dBm sweeping from 520/550MHz?
Best Regards
J.ClarkHi Clark,
I’m not familiar with any sort of conversion, but the common way to measure power of a modulated/non-CW signal is to use the channel power measurement. You can enable/configure that in the measurements control panel. When using the SA44B, for the most accurate channel power measurements, disable spur rejection in the File->Settings menu.
Let us know if you have additional questions.
Regards,
Andrew
