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.

= external, low-latency external trigger mode = on)
