TBS 5922se

[Lambda]

Greeting! I have some problem with TBS5922se card .. Card on Qpsk2 modulation is often measured signal 0dB .. It also shows a very weak RF level, typically 60-90dBm .. The official specifications state Input level: -69 to -23dBm
The card does not react to a change BBG value, assume that the necessary changes in streamreader file?
