zoomable, in which case the scroll cursor is shown. When the zoom cursor is in the
Timelines
or
Zoomed Throughput Graph
zooming occurs around the point in time where the zoom cursor is
positioned. When the zoom cursor is outside the
Timelines
and the
Zoomed Throughput Graph
the
left edge of those displays is the zoom point.
The Throughput Graph s for Classic Bluetooth in the Coexistence View and the Bluetooth Timeline
can look quite different even though they are plotting the same data. The reason is that the Coexistence
View uses timestamps while the Bluetooth Timeline uses Bluetooth clocks, and they do not always match
up exactly. This mismatch can result in the data for a particular packet being included in different intervals
in the two
Throughput Graph s, and can have a significant impact on the shapes of the two respective
graphs. This can also result in the total duration of the two Throughput Graph s being different.
Another factor that can affect total duration is that the Bluetooth
Timeline
's
Throughput Graph
stops at
the last Classic Bluetooth packet while the
Coexistence View
’s
Throughput Graph
stops at the last
packet regardless of technology.

All source MAC addresses that have been seen during this session are listed in the dialog that appears when
the
Set
button is clicked. Also listed is the last source MAC address that was set in the dialog in the previous
session. If that address has not yet been seen in this session, it is shown in parentheses.
