trigger segment equals the length of the memory
segment minus the delay. When the length of the delay is equal to, or exceeds,
the length of the memory segment, only post

9.3.3 More on continuous data storage
The most important difference between continuous data storage and sweeps
in a GEN3i is the fact that sweeps are stored in on
-
board volatile RAM, while
continuous storage takes place on the controlling PC's hard disk (or local hard
disk when installed).
The continuous data storage provides three modes:
l
Standard The continuous mode is standard when storage is started and is
stopped manually as depicted below:
