ABSTRACT:
A test method for determining radio frequency (RF) path loss between an RF source and an RF receiver for a plurality of RF channels in a given RF frequency may include determining RF path losses for selected RF channels within the given RF frequency band, and determining an RF path loss function based upon the RF path losses of the selected RF channels. The method may further include determining an RF path loss for at least one other channel within the given RF frequency band based upon the RF path loss function.
