RFmxTdscdmaMX.GetReferenceLevelHeadroom Method

Gets the margin RFmx adds to the Reference Level method. The margin avoids clipping and overflow warnings if the input signal exceeds the configured reference level. RFmx configures the input gain to avoid clipping and associated overflow warnings provided the instantaneous power of the input signal remains within the reference level plus the reference level headroom. If you know the input power of the signal precisely or previously included the margin in the reference level, you could improve the signal-to-noise ratio by reducing the reference level headroom.
