Product-Specific Commands—Description
The End of analysis event does not necessarily
correspond to the last event of a fiber link. It
indicates that the analysis has stopped before the
end of the link because the instrument has
reached the limit of its dynamic range.
In most cases, the OTDR analysis will return the
type of the last event as being either reflective or
non-reflective (event type 3 or 2).

(corresponding to 4 events).
CALC:EVEN? TRC1,1 (where 1 is the event
number. Values 1 to 4 are valid). Returns the
event corresponding to the specified number.
