The user-defined (stair) is the discrete alternative of continuous User-defined function described above. The Stair function is defined through a discrete set of values Xi, i = 1…N and associated probabilities S(Xi) . This is the pair of set (Xi, S(Xi)) where Xi represents all possible values that might be assigned to the variable, whereas S(Xi) represents their cumulative probabilities:

This example returns frequencies that will operate at 904 MHz, for another snapshot it will be 902 MHz, etc…
