Tip:
In a segmented frequency sweep, it is possible to set the sideband (
SBANd
)
parameter individually for each segment; see
. The
[SENSe<Ch>:]FREQuency:SBANd
setting is global and not valid for
segmented sweeps. The two sideband settings do not overwrite each other.
Note
: For the R&S
ZNLE only AUTO mode is supported.
Suffix:
<Ch>
.
Channel number. This suffix is ignored; the setting applies to all
channels in the active channel setup.
Parameters:
<Sideband>
POSitive | NEGative | AUTO
POSitive
LO > RF; the LO frequency is always above the measured RF
frequency.
NEGative
LO < RF; the LO frequency is always below the measured RF
frequency.
AUTO
The analyzer auto-selects the LO frequency, depending on the
receiver (RF) frequency.
*RST:
AUTO
Example:
*RST; :SWE:TYPE?; :FREQ:SBAN?
Query the *RST values for the sweep type and the sideband set-
ting. The response is
LIN
(linear frequency sweep) and
AUTO
(automatic setting of the LO frequency).
Manual operation:
See
[SENSe<Ch>:]FREQuency:SEGMent:AXIS
<Scale>
Selects either frequency based or point based x-axis for segmented sweeps.

Parameters:

POINt | FREQuency
Example:
SENSe:SEGMent:INSert 1MHZ, 1.1MHZ, 101, -21DBM,
0.5S, 0, 10KHZ
SENSe:SEGMent:INSert 2MHZ, 3MHZ, 101, -21DBM,
0.5S, 0, 10KHZ
Create two sweep segments with different frequency spans,
each with 101 sweep points.
SENSe:SEGMent:FREQuency:AXIS POINt
Select the point based frequency axis. The first 101 sweep
points are distributed over the left half of the diagram, the sec-
ond 101 points over the right half.
