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.
This setting is valid for sweep types with equidistant sweep points only. It does not apply to
logarithmic and segmented sweeps.
<Ch>
Channel number.
<step_size>
Stimulus step size.
Range [def.
unit]
Depending on the other channel settings. The minimum step size is equal to the
sweep span divided by the maximum number of points minus one
([SENSe<Ch>:]SWEep:POINts), the maximum step size is equal to the sweep span
([SENSe<Ch>:]FREQuency:SPAN). See also description of manual control and
program example below. [–]
*RST value
The default step size is equal to the default sweep span of the analyzer divided by
the default number of points minus one.
SCPI,
Command
Types
Confirmed, with query.
Example:
*RST; SWE:STEP?
Query the default step size. For a 6 GHz analyzer, the response is 29998500.
29998500 Hz = (6 GHz – 300 kHz) / 200.
SWE:STEP UP
Increase the step size.
FREQ:STOP?; :SWE:POIN?
Query the stop frequency of the sweep and the number of points. Increasing the
step size has changed both values.
[SENSe<Ch>:]SWEep:TYPE LINear | LOGarithmic | SEGMent
Selects the sweep type (frequency) 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
