Timing Chart of I/O Port Signal (Point trigger function:on, Low-latency external trigger mode: on)
When both the point trigger function and the low-latency external trigger
mode are on, the /EXTERNAL TRIGGER signal must be inputted for each
measurement point during a single sweep. The /INDEX signal goes to the
High level before staring measurement of the first measurement point and
returns to the Low level after the completing measurement of all
measurement points.
The /READY FOR TRIGGER signal goes to the Low level when the
instrument is ready to accept the trigger signal for the first point and then
goes to the High level when the trigger signal for the first point is received.
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 and the low-latency external trigger
mode is off, 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.
