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:TIME?
Query total sweep time.
SWE:POIN 2010
Multiply the (default) number of points by 10.
SWE:TIME?
Query total sweep time again. The analyzer estimates a sweep
time that is also multiplied by 10.
[SENSe<Ch>:]SWEep:SPACing LINear | LOGarithmic
Defines the frequency vs. time characteristics of a frequency sweep (Lin. Frequency or Log Frequency) .
The command has no effect on segmented frequency, power or time sweeps.
Note: Use
[SENSe<Ch>:]SWEep:TPYE
to select sweep types other than Lin. Frequency or Log.
Frequency.
<Ch> Channel number.
LINear The stimulus frequency is swept in equidistant steps over the
frequency range. In a Cartesian diagram, the x-axis is a linear
frequency axis.
LOGarithmic The frequency is swept in equidistant steps on a logarithmic scale.
In a Cartesian diagram, the x-axis is a logarithmic frequency axis.

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:SPAC LOG
Change to sweep type Log Frequency .
[SENSe<Ch/Tr>:]SWEep:SRCPort 1 | 2 | 3 | 4
Selects a source port for the stimulus signal (Drive Port) . The setting acts on the active trace. The effect
of the drive port selection depends on the measurement parameter associated to the active trace:
•
If an S-parameter S
<out><in>
is measured, the second port number index <in> (input port of the
DUT = drive port of the analyzer) is set equal to the selected drive port: Drive port selection
affects the measured quantity.
•
If a wave quantity or a ratio is measured, the drive port is independent from the measured
quantity:
<Ch/Tr>
Channel number used to identify the active trace. If unspecified
the numeric suffix is set to 1.
