Example:
SWE:TIME 1
Set a total sweep time of 1 s.
SWE:TIME:AUTO?
A query returns the value 1.
[SENSe<Ch>:]SWEep:TYPE LINear | LOGarithmic | SEGMent | POWer | CW
Selects the sweep type, i.e. the sweep variable (frequency/power/time) and the position of the sweep
points across the sweep range.
<Ch>
Channel number.
LINear Lin. frequency sweep at constant source power
(
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude]
)
. The stimulus frequency (
[SENSe<Ch>:]FREQuency:...
) is swept in
equidistant steps over the frequency range. In a Cartesian diagram, the
x-axis is a linear frequency axis.
LOGarithmic Log. frequency sweep. The frequency is swept in equidistant steps on a
logarithmic scale. In a Cartesian diagram, the x-axis is a logarithmic
frequency axis.
SEGMent Segmented frequency sweep. The sweep range is composed of several
continuous frequency ranges or single frequency points defined by
means of the commands in the
[SENSe<Ch>:]SEGMent<Seg>...
subsystem.
POWer Power sweep. The measurement is performed at constant frequency
(
SOURce<Ch>:FREQuency<Pt>:CW|FIXed
) but with variable
generator power that is swept in linear, equidistant steps over a
continuous range (
SOURce<Ch>:POWer<Pt>:STARt
,
SOURce<Ch>:POWer<Pt>:STOP
). In a Cartesian diagram, the x-axis is
a dB-linear power axis.
CW Time sweep. The measurement is performed at constant frequency
(
SOURce<Ch>:FREQuency<Pt>:CW|FIXed
) and source power
(
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude]
)
and repeated over a specified period of time at constant time intervals.
POINt CW Mode sweep, time sweep triggered according to the current trigger
settings.

Command
Types
Device-specific, command or query
Example:
FUNC "XFR:POW:S12"
Activate a frequency sweep and select the S-parameter S12 as
measured parameter for channel and trace no. 1.
SWE:TYPE LOG
Change to sweep type Log Frequency .
