Channel Measurements
RRC Weighting
RRC, or Root-Raised-Cosign weighting, is offered with Channel Power and
ACPR measurements.
When RRC Weighting is applied to transmitted and received power, the edges
of the channel are 'smoothed' to help prevent interference. To accurately
measure a channel that has RRC weighting, set the same value of RRC
weighting as that used in the transmitter and receiver.
