Note:
Checking this option does not affect the sample. It only allows larger sample sizes.
Note:
If traffic is balanced on ports, sample size is the same whether you check or uncheck the
Sampling Memory Usage Optimization option.
Note:
Memory Assignment depends on traffic load distribution at the time when the system tries to
re‐assign physical links to memory banks. Therefore, if you repeat a capture with the same
Sampling Memory Size and Segment Number parameters, the resulting sample size may not be
the same. However, if traffic load distribution is similar, sample size will be similar.
Note:
The buffer status indicator shows buffer by FPGA, not by port.
If the Sampling Memory Usage Optimization Option is Not Checked
Each physical link (or logical link if MUX is enabled) is assigned to a specific memory space
(memory bank), depending on the Sampling Memory Size and Segment Number
parameters.
Important: If any physical link fills its memory bank, the recording process stops. Other
memory banks will typically be less than full (and can be empty). The sample file might be
smaller than the user‐defined Sampling Memory Size. You might even think that the
Analyzer malfunctioned.
