Occupied Power Bandwidth Calculation

This program calculates the occupied bandwidth of the carrier signal. It rst computes the
combined power of all signal responses contained in the trace. It then calculates the point for
which 0.5 % of the total power lies to the right of the right maker and to the left of the left
marker.
Before running the program, set up the measurement, calibrate the analyzer, and connect the
signal to the input port.
