User manual

The height of Classic Bluetooth and Bluetooth low energy packets indicates their frequency range (1 MHz and 2
MHz respectively). Since 802.11 channels are so wide (22 MHz), 802.11 packets are drawn with an arbitrary 1
MHz height and centered within a separate frequency range box which indicates the actual frequency range.
Selecting a packet by clicking on it draws a selection box around it (as shown above) and highlights the
applicable entries in the legend.
Figure 4.68 - Highlighted entries in the legend for a selected packet.
Summary information for a selected packet is displayed in the timeline header.
Figure 4.69 - Timeline header for a single selected packet.
When multiple packets are selected (by dragging the mouse with the left button held down, clicking one
packet and shift-clicking another, or clicking one packet and pressing shift-arrow), the header shows Gap
(duration between the first and last selected packets), Timestamp Delta (difference between the
timestamps, which are at the beginning of each packet), and Span (duration from the beginning of the first
selected packet to the end of the last selected packet).
