3.4       Occupied Bandwidth and 26 dB Bandwidth
3.4.1     Test Procedures
1.    Set resolution bandwidth (RBW) = 1% ~ 5 % of OBW, Video bandwidth = 3 x RBW
2.    Detector = Peak, Trace mode = max hold.
3.    Sweep = auto couple, Allow the trace to stabilize.
4.    Using occupied bandwidth measurement function of spectrum analyzer to measure occupied bandwidth
5.    Measure the maximum width of the emission that is constrained by the frequencies associated with the
      two outermost amplitude points (upper and lower) that are attenuated by 26dB relative to the maximum
      level measured in the fundamental emission.
