Resolution Bandwidth - Berkeley Varitronics Systems BumbleBee-TABLET Manual

3.4 Resolution Bandwidth:

The BumbleBee measures the energy present within the frequency bins. The width of each bin is equal to
the Resolution bandwidth.
Fig 13.1 Burst of Signal Energy as observed using a 100 KHz resolution bandwidth.
Fig 13.2 Burst of Signal Energy as observed using a 500 KHz resolution bandwidth.
The Resolution Bandwidth of the trace shown in Fig 14.2 is 500 KHz. Each point in the spectrum above
represents the total energy present in a frequency bin 500 KHz wide. A lower Resolution Bandwidth is
very useful in accurately capturing and measuring individual frequency components within the spectrum.
However, for a large span, a smaller Resolution Bandwidth would result in a longer sweep time. A higher
Resolution Bandwidth can be used for a large span to reduce the sweep time. A Resolution Bandwidth
greater than or equal to the bandwidth of the signal can be used to measure the Channel Power.
