10. Instant Timing Pane
The Instant Timing pane provides a unique and intuitive way to understand various timing characteristics of
Bluetooth traffic as well as all other traffic types captured by the analyzer, including logic signals.
Bluetooth packets are presented chronologically left to right and are uniquely color-coded per the packet’s
sender. For Bluetooth, each master device is provided its own line (row), with packets to and from the master
device shown horizontally across the
Instant Timing pane.
Additionally, the
Instant Timing pane displays Wi-Fi, WPAN, and HCI traffic, generic communications (UART,
SPI, SWD, I2C), logic signals, a representation of throughput, and statistical information, all in synchronization.
The
Instant Timing pane provides for quick and easy timing measurements, slot timing, timing cursors, zoom
and pan features, detailed packet flyovers, color-coded assignments to devices, and other navigation tools.
A throughput graph tracks data-rate characteristics for L2CAP and SCO/eSCO transfers. In the
Navigator bar,
the user is provided with a global summary of throughput over the entire capture, as well as a bracketed window
that can be used to pan and zoom the
Instant Timing display.
A statistical graph provides a synchronized understanding of retransmissions, packet errors, and header errors.
The
Instant Timing pane is linked to the Overviews and the Instant Spectrum view. It is manually linked to
the
Instant Piconet pane by the Instant Piconet cursor, which when scrolled, updates the Instant Piconet view
per its current location. Conversely, when events are selected in the Overview or the
Instant Spectrum view,
this cursor is re-positioned accordingly.
Note that since the analyzer is designed to be passive (does not interact with or synchronize
to Bluetooth device clocks), timing measurements will be extremely precise.
To access the Instant Timing pane:
1. Select View | Instant Timing from the menu.
