Upper tone source:
NONE – no source selected (for query only)
PORT – internal second source at port <arg1>
GENerator – configured external generator no. <arg1>
*RST: NONE
<arg1> Analyzer port number or generator number
Range: 1 to number of ports of the analyzer or number of
configured external generators
*RST: n/a (no analyzer or generator port selected)
Example: See [SENSe<Ch>:]FREQuency:IMODulation:LTONe
Manual operation: See "Upper Tone" on page 338
[SENSe<Ch>:]FREQuency:SBANd
<Sideband>
Defines whether the analyzer measures with a local oscillator frequency LO below or
above the RF input frequency.
Tip: In a segmented frequency sweep, it is possible to set the sideband (SBANd)
parameter individually for each segment; see [SENSe<Ch>:]SEGMent<Seg>:
DEFine. The [SENSe<Ch>:]FREQuency:SBANd setting is global and not valid for
segmented sweeps. The two sideband settings do not overwrite each other.
Suffix:
<Ch>
.
Channel number. This suffix is ignored; the setting applies to all
channels in the active recall set.
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 "Image Suppr." on page 632
