Enter an external trigger delay time.
External trigger delay time and point trigger interval
External trigger pulses, supplied until the next measurement becomes ready after the start
of a one-point measurement, are ignored, and the next trigger is generated by a pulse
supplied after the completion of the one-point measurement.
The time until the next trigger can be accepted after the start of a one-point measurement
depends on the IFBW and other settings of the analyzer. For example, in the case of a
frequency’s zero-span measurement, the time until the next measurement is ready after the
start of a one-point measurement is obtained by dividing the time required for a single
sweep in On Sweep mode, instead of On Point mode, by the number of measurement
points. If you use the point trigger function with external trigger pulses that are wider than
this time, point trigger measurement is performed at each pulse input.
The figure below shows the timing chart of an external trigger when the point trigger
function is on.
