:TIME
[SOURce:]SWEep:TIME <number> selects the duration of the sweep or frequency
list generation when
TRIGger:SWEep:SOURce is set to TIMer. The duration is the
time from the start of the sweep or list until when the last frequency begins to be
output. The value set by this command is coupled to the
TRIGger:SWEep:TIMer
command value by the following equation:
TIME = TIMer * (points - 1)
where points is the
[SOURce:]SWEep:POINts value for frequency sweeps, or the
length of the frequency list for frequency list generation.
When changing the frequency list length when
[SOURce:]FREQuency[1]:MODE
LIST
is set, or the [SOURce:]SWEep:POINts value when any other MODE is set, the
TIME or TIMer value remains the same, depending on which command,
[SOURce:]SWEep:TIME or TRIGger:SWEep:TIMer respectively, was most recently
sent. The other value is changed based on the new points value.

MINimum selects 1.25 mS * (points - 1); MAXimum selects 4.19430375 S * (points - 1).
The above values bound the valid range for time.
Comments • When performing multiple sweeps or list generations with ARM:SWEep:SOURce
IMMediate
set, the last frequency point is output for the same length of time as all
other points. The
SWEep:TIME value is the time from the start of the sweep or
list until the last frequency begins to be output and does not include the time for
the last frequency point. Therefore, if a specific sweep repetition time is desired,
SWEep:TIME should be set according to the following equation:
SWEep:TIME = time * (points - 1) / points
Thus, to set a repetition time of 1 S for a 5 point sweep,
SWEep:TIME should be
set to .8 S.
