Frame Display
filtering has no effect here in that packets that are filtered-out in
Frame Display
are still used here as long as they otherwise meet the criteria for each radio button as described
below.
All
packets are used for average throughput, and
packets occurring in the last 1 second of the session
are used for 1 second throughput, except that
Bluetooth low energy packets from non-configured devices can be excluded as noted above.
Selected packets (the selected packet range is
shown in the timeline header) are used for average
throughput, and packets in the 1 second duration
ending at the end of the last selected packet are used for 1 second, except that Bluetooth low
energy packets from non-configured devices can be excluded as noted above.
Figure 4.47 - Timeline Header Showing Selected Packets
The viewport is the purple rectangle in the
Throughput Graph
and indicates a specific starting
time, ending time, and resulting duration. Packets
that occur within that range of time are used for average throughput, and packets in the 1 second
duration ending at the end of the last packet in the viewport time range are used for 1 second
throughput, except that
Bluetooth low energy packets from non-configured devices can be
excluded as noted above.

The width of each indicator is the largest 1 second throughput seen up to that point for that technology
(Classic
Bluetooth , Bluetooth low energy, or 802.11), where the 1 second throughput is calculated anew
each time another packet is received. The 1 second throughput indicator will never exceed this width,
but the average throughput indicator can. For example, the image below has a large average throughput
because the Selected radio button was selected and a single packet was selected, and the duration in that
case is the duration of the single packet, which makes for a very small denominator in the throughput
calculation. When the average throughput exceeds the indicator width, a plus sign (+) is drawn at the right
end of the indicator.
