The following section shows the various ways the HP E1313/E1413 can
control channel scanning, and how to select the trigger mode to accomplish it.
The Continuous Mode provides the fastest scanning. The time between
channel measurements is controlled by the trigger timer interval and is
consistent from channel-to-channel as well as from the last channel in the
scan list back to the first channel in the list when the scan list is re-executed.
ARM
t is the sample time between channels.
c
The large arrow is the arming event or signal. The smaller arrows
are sample triggers generated by the HP E1313/E1413 when
stepping through the channel list.
