5.10.3 Next Trigger
When more than one record sequence is performed without first
erasing the record memory, it is possible to have more than one trigger point
in the record memory of the Analyzer488. This command places the cursor
on the next location (a location recorded after the present location) that was
marked as a trigger point.
If multiple record sequences were performed, it is possible that the
record memory may be overwritten one or more times. In this case, the next
trigger location may be at a lower location than the current trigger location.
5.10.4 Previous Trigger
When more than one record sequence is performed without first
erasing the record memory, it is possible to have more than one trigger point
in the record memory. This command places the cursor on the previous
location (a location recorded before the present location) that was marked as
a trigger point.
If multiple record sequences were performed, it is possible that the
record memory may be overwritten one or more times. In this case, the
previous trigger location may be at a higher location than the current trigger
location.
