progress bar' in the toolbar will indicate the part of recorder memory that is filled with data.
Note that when the Recorder is not triggered yet, only the part before the trigger indicator in the progress
bar (the little vertical line) will be filled. If this part becomes full, recording continues and old data will be
removed from the memory while the new data is stored (cyclic buffer). After the Recorder is triggered, the
data will be stored after the trigger position until the recorder memory is full.
If recorder memory becomes full, the recording is automatically stopped. You can also stop the recording
manually by selecting the 'Stop' command in the 'Recorder' menu, or clicking the 'Stop Recording' button
in the toolbar.
9.1.1.3. Download and process symbols
When the recording has been stopped, you can download the recorded data by selecting the 'Download'
command in the 'Recorder' menu or clicking the 'Download recorded data from Analyzer' button in the
toolbar.
After the download, the data can be viewed using the different kind of views.
The recorder records every bit that is send over the bus, the processing of the recorded data is done in
software on the host. The processing starts simultaneously with the downloading of the data. If more than
one analyzer is used to examine a bus, the downloading can also be done in parallel. The progress dialog
will show the progress of each process. As the amount of data can easily get too large to fit in memory,
the decoded data is saved to file during the process.
9.1.1.4. Triggering
The Recorder can be triggered in different ways:
·
You can click the 'Trigger' button in the toolbar or invoke the 'Trigger' command in the 'Recorder' menu.
· You can apply a trigger pulse on the external trigger input on the Analyzer device.
The hardware-trigger logic will be described in full detail in ' Filter/Trigger '. Please be aware that for
FireStealth only the General Trigger functionality is available.
Each time you start the Recorder, a check is made if the user changed some settings in the Filter/Trigger
Settings window. If so, the user will be asked if these changes need to be activated or ignored before
starting the recording.
