The occupied bandwidth is the difference in frequency between the points where the integrated power crosses 0.5% and 99.5% of the total power in the spectrum.

What is instantaneous bandwidth and occupied bandwidth?
IBW and OBW refers to bandwidth defined by the frequency range within which the Base Station can be operated, defined by the band-pass filter of the BS, e.g. 3.4 – 3.8 GHz (400 MHz)
What does if bandwidth mean?
IF Bandwidth is a range of frequencies centered around the IF frequency, limited by the 3dB amplitude points. Intermediate frequencies are used for three general reasons. At very high (gigahertz) frequencies, signal processing circuitry performs poorly.
What is the OBW and why is it important?
Occupied bandwidth (OBW) measures the bandwidth that occupies a certain power specified as a percentage of the total power in the acquired spectrum. A spectrum is configured for span, resolution bandwidth, and sweep time. The total power is measured after RBW filtering and averaging.
What is instantaneous bandwidth in RF?
Real-Time (Instantaneous) Bandwidth
This means that the device can continuously acquire 20 MHz of RF spectrum without re-tuning the local oscillator (LO). Real-time bandwidth is largely determined by the RF analog front end of the instrument.
