Note: Use [SENSe<Ch>:]SWEep:TYPE 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.
*RST value
LINear
SCPI, Command
Types
Confirmed, 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:SPAC LOG
Change to sweep type Log Frequency.
[SENSe<Chn>:]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:
<Chn>
Channel number used to identify the active trace. If unspecified the numeric
suffix is set to 1.
1 ...
Test port number of the analyzer, 1 to 2, 3 or 4, depending on the analyzer
model.
*RST value
1 (test port 1)
SCPI, Command
Types
Device-specific, with query.
Example:
CALC4:PAR:SDEF "Ch4Tr1", "A1"
Create channel 4 and a trace named Ch4Tr1 to measure the wave quantity a1.
The trace automatically becomes the active trace.
SENS4:SWE:SRCP 2
Select drive port 2 for the active trace.
[SENSe<Ch>:]SWEep:STEP <step_size>
Sets the distance between two consecutive sweep points.
