SWEep Linear or logarithmic frequency sweep, depending on the selected
spacing (
[SENSe<Ch>:]SWEep:SPACing LINear | LOGarithmic
).
The frequency range is set via
[SENSe<Ch>:]FREQuency:STARt
etc.
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 the
[SENSe<Ch>:]SEGMent<Seg>...
subsystem.
CW | FIXed Time sweep. The measurement is performed at constant frequency
(
[SENSe<Ch>:]FREQuency:CW|FIXed
) and repeated over a specified
period of time at constant time intervals.
*RST value SWEep
SCPI,
Command
Types Confirmed (with device-specific *RST value and parameters), command
or query.
Example:
FREQ:MODE CW
Activate a time sweep.
FREQ:CW 100MHz
Set the CW frequency to 100 MHz.
[SENSe<Ch>:]FREQuency:SBANd POSitive | NEGative | AUTO
Defines whether the analyzer measures with a local oscillator frequency LO below or above the RF
input frequency.
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.
<Ch> Channel number.
POSitive The LO frequency is always above the measured RF frequency.
NEGative The LO frequency is always below the measured RF frequency.
AUTO The analyzer auto-selects the local oscillator frequency, depending on
the receiver (RF) frequency and the test port.
*RST value AUTO
SCPI,
Command
Types Device-specific, command or query.
Example:
*RST; FREQ:TYPE?; :SBAN?
Query the *RST values for the sweep type and the sideband setting.
The response is
LIN (linear frequency sweep) and AUTO (automatic
setting of the LO frequency) .
