When multiple analyzers are properly synchronized then they can be controlled as one large FireSpy with
many buses just as normally is done controlling a single FireSpy. The following picture shows the
Recorder when 3 triple analyzers are open and a Recording was made with only 6 out of 9 buses selected.
7.2. Time View
The Time View is one of the possible views in the Recorder which you can use to investigate the recorded
packets and events. It displays all packets and events on a time line. The relative positions of the packets
and events correspond to the time the packet or event was recorded and the length of packets in the view
correspond to the actual duration of the packets.
Note that before each packet you will also see the packet prefix. The duration of this prefix indicates the
time the transmitting node needed to start transmitting the data from the moment that it has ownership of
the bus. A shorter prefix means a faster reaction time of the node and a shorter overall packet transmit
time, and thus a better bus efficiency
Besides the Reset event, some other events can be displayed in the Time View. For instance the position
of subaction gaps and arbitration-reset gaps. These are only displayed if the recording of these events are
enabled (see
Filter/Trigger Settings ) and when zoomed in far enough.
The Time View also displays the position of the trigger.
7.2.1. How to use it
You can display/remove the Time View by checking/unchecking the Time View item in the View menu of
the Recorder. There is also a shortcut key to toggle the state. An example of the Time View is dispayed
