When measurement of all measurement points is completed and the
instrument is ready to receive the trigger signal for the first point of the
next sweep, this signal goes to the Low level again.
When the point trigger function is ON, the /READY FOR TRIGGER signal
goes High each time a trigger signal is received and goes Low when
measurement of each measurement point is completed and the instrument
is ready to accept a trigger for the next measurement point.
The times of T1 and T2 are the same as those when the point trigger
function is OFF. For more information, see Timing chart of I/O Port Signal
(Point trigger function:OFF).
