SWE:POIN 2010
Multiply the (default) number of points 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 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.

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
Selects a source port for the stimulus signal
(Drive Port)
. The setting acts on 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.
<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.
*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.
