Example:
*RST; :SYST:FREQ? MIN; :SYST:FREQ? MAX
Query the frequency range of the analyzer.
FREQ:CENT 100MHz
Set center frequency to 100 MHz.
FREQ:SPAN 50000
Set frequency span to 50 kHz.
Manual operation:
"Start Frequency / Stop Frequency / Center Frequency /
Note:
The measurement range defined by means of the center frequency and the cur-
) must not exceed the allowed frequency
range of the analyzer. If necessary, the span is reduced to min (<CenterFreq>
–
f
MIN
,
f
MAX
–
<CenterFreq>).
[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>:]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).
