• The total channel sample time is the minimum sample time plus the user-
programmed channel delay. The longer the channel delay, the longer it takes to
sample the channel.
• The total scan sweep time is sum of the channel sample times of all the channels
scanned. A scan sweep will start when the selected trigger source is asserted if a
previous scan sweep is not still in progress (see "Trigger Type" on page 4-7).
• The interval at which scan sweeps occur can be fixed by programming the trigger
type to Timer and setting an interval time.
