For example, to run cbAInScan on one channel at 18 MHz with the CONTINUOUS option set, determine the
minimum sample size from the table to be 262,144 (since the Rate is between 14 and 20 MHz). The minimum
contiguous memory is calculated as:
(262,144 / 512 ) = 512 KB
Minimum Sample
Size (two packets)
Min Contiguous
Memory (based on
Min Sample Size)
*Note that the EventData for ON_PRETRIGGER events may not be accurate. In general, this value will be below
the actual number of pretrigger samples available in the buffer.
