• Truncate Data Fields to 4 Quadlets — Selecting this option causes all data
blocks to be truncated after the first four quadlets. This feature is useful
when the contents of the data are not as important as the number of
packets recorded. Truncating the data packets leaves more room in the
buffer for other data.
• Beep When Trigger Occurs — When this option is selected, the analyzer
box will beep when the trigger event is detected.
•
Save External Interface Signals — Selecting this option causes signals
from the External Interface Breakout Board to be saved in the recording
file. The analyzer records external signals provided by the user (bits
I0-I7on the External Breakout Board). These bits, along with output bits,
are sampled once per each packet's quadlet during recording. Selecting
this option instructs the software to save those signals in the recording file
during data uploading so they can be viewed and analyzed later. Select
this option only if you provide valuable data on external inputs/outputs.
Step 4
Set the Buffer Size. Use the slider or the arrow keys on the keyboard to adjust
the buffer size. It can be set anywhere between 640 kilobytes and 64
megabytes. This determines the amount of data that the analyzer will record.
Step 5
Set the Trigger Position (for manual and event trigger recordings only). Use
the slider or the arrow keys on the keyboard to adjust the trigger position. It
can be set anywhere between 1 and 99%. This determines the amount of data
that will be recorded before and after the trigger event. For example, if the
slider is set at 30% post-triggering, then the first 70% of the data in the
recording will be things that happened before the trigger, and the last 30%
will be things that occurred after the trigger.
Step 6 (Optional) Enter an Options Name. You can use the options name to identify
the current set of recording options. If you save the settings, then the next
time the options file is loaded, the options name is displayed in the text box.
Step 7 (Optional) Set the Trace Filename & Path. Use this option to specify a name
and location for the Trace file that is generated with the current set of
recording options. If not specified, the default name, data.fdb, and the default
location, \FireInspector, are used.
Step 8 Click OK to apply the settings and close the Recording Options dialog.
