than the specified data points prior to the triggering event. For more detail, (see

“Pre‐

Trigger” on page 103.

)

Note:

Trigger Position only works when the triggering option is Pattern.

In certain cases, when one port is recording traffic and filling up the memory much faster
than another port, you might see traffic appearing only on one port for a while, and the
other port's traffic will only appear later. This occurs as a function of the trigger position,
and is normal, expected behavior of the analyzer.

Trace File Name

Click the ellipses next to the Sample File Name text box and choose a file name and
location for the results of your current project.

Auto Run

To repeat the current capture and trigger setup automatically, check the Auto Run
checkbox and enter the number of times in the Number of Run text box. The capture and
trigger repeat automatically for the specified number of times, and the results are saved
in consecutively numbered Sample.scs files.

Memory Size

In the Protocol Analyzer Settings tab, you can allot memory for the trace recording. Check
Entire Memory to allow recording to use the whole memory, to capture the maximum
amount of trace data. (Minimum size of memory is 2 GB. Maximum size of memory is
16 GB.)

Partial Memory

To reduce the memory size, check Partial Memory and enter a buffer size in kilobytes, up
to the memory size in megabytes.

Note:

If the size of a data packet exceeds the buffer memory allocation, the project runs, but no data

capture occurs. You must increase buffer memory size to a value greater than the packet size.

Segmented Memory

Alternatively, you can use Segmented Memory. Enter an integer # of Segment, from 1 to
32, then enter an integer Segment Size in kilobytes, up to the memory size in megabytes
divided by the number of segments. The default segment size is 10 MB.

Each time a trigger condition occurs, the system records a new segment. You can use a
Snapshot or Pattern trigger, but not Manual Trigger. As the same trigger automatically
repeats, the system makes the number of segments that you entered.

Upload Manager

To upload segments manually in the Upload Manager (see

Figure 2.71 on page 106

),

select the Don’t upload segments and open upload manager automatically checkbox. 
To upload segments automatically for display as the system creates them, do not select
the checkbox.
