RRC Filter
Turns the Root Raised Cosine filter on or off. This filter is the type specified in the NADC and
3GPP W-CDMA standards and is only available when 3GPP W-CDMA, NADC, or Tetra is
selected as the Radio Std from the Mode Setup menu. If 3GPP W-CDMA is selected, the
rolloff value (alpha) for the filter will be initially set to 0.22. T is set to 1/RefBW (default 260
ns). If NADC is selected, the rolloff will be initially set to 0.35. T is set to 1/RefBW (default
42 ms). If TETRA has been selected, the rolloff will be initially set to 0.35. T is set to
1/RefBW (default 55.6 ms). The rolloff value can be changed using Filter Alpha.
The filter is unavailable when the measurement method is set to RBW.
