<Format>
LINear | LOGarithmic | POWer | CW | POINt | SEGMent
LINear - linear frequency sweep at constant source power
(
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:
(
[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 - logarithmic 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 fre-
quency points defined by means of the commands in the
[SENSe<Ch>:]SEGMent<Seg>...
subsystem.
POWer - power sweep. The measurement is performed at con-
stant frequency (
SOURce<Ch>:FREQuency<PhyPt>:FIXed
but with variable generator power that is swept in linear, equidis-
tant steps over a continuous range
(
SOURce<Ch>:POWer<PhyPt>:STARt
). 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<PhyPt>:FIXed
) and
SOURce<Ch>:POWer<PhyPt>[:LEVel][:
) 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.
*RST:
LINear
Example:
*RST
Reset the analyzer, activating a linear frequency sweep.
SWE:TYPE LOG
Change to a logarithmic frequency sweep, resetting the stimulus
values of the sweep points.
Manual operation:
See
[SENSe<Chn>:]SWEep:SRCPort
<Port>
Sets/gets the source port for the stimulus signal. The setting acts on the active trace.
The effect of the drive port selection depends on the measurement parameter associ-
ated 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 of the mea-
sured quantity:
