ACP Alpha (TEDS)
0.35 (See Using Standard Setups/Presets)
0.02 or 300 Hz / ACP Adjacent Channel Power: The power from a modulated communications channel that leaks into an adjacent channel. This leakage is usually specified as a ratio to the power in the main channel, but is sometimes an absolute power. BW (whichever is higher) to 1.0
specifies the alpha for your ACP filter in your ACP PvT TEDS demodulation analysis measurement.
In the ACP PvT measurement, the upper and lower adjacent channels are filtered through a Root Raised Cosine (RRC) filter with a default 18kHz bandwidth and a default .35 alpha. The filter alpha determines the shape of the adjacent channel filter. and the .35 value means the adjacent channel filter roll-off region on each side is 35% of the filter's bandwidth. For more information, see Root Raised Cosine Filter.
