„Description: Waveform Trigger Log Registers included in this block: See Registers 36865-36882.

8.82: System Event Log Header (37505-37522)

Memory Size: 4-byte unsigned integers representing the amount of memory, in bytes, allocated to the log.

Record Size: 2-byte unsigned integers representing the size, in bytes, of a record in the log.

First Index: 2-byte unsigned integers representing the Index of the First (Oldest) record in the log.

Last Index: 2-byte unsigned integers representing the Index of the Last (Newest) record in the log. The value 0x0FFFF indicates that the log is empty.

First Time Stamp: Thses registers (8 bytes) hold the Time Stamp from the First (Oldest) record in the log.

Time Stamp Bytes

Byte	Range	Description
0	0-255	Century
1	0-99	Year
2	1-12	Month
3	1-31	Day
4	0-23	Hour
5	0-59	Minute
6	0-59	Second
7	0-99	Centisecond

Last Time Stamp: These registers hold the Time Stamp from the Last (Newest) Record in the log. The byte order and description are the same as for the First Time Stamp.

Valid Bitmap: Undefined.

Max Records: A 2-byte unsigned integer represents the total number of records the log is capable of holding. In order to maintain a one-for-one relationship in parallel logs, the maximum number of records that a log can hold is defined by the log that holds the fewest records. Logs capable of hold- ing more records are restricted.
