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: See "Start Frequency / Stop Frequency / Center Frequency /
Span Frequency" on page 311
Note: The measurement range defined by means of the center frequency and the cur-
rent span ([SENSe<Ch>:]FREQuency:SPAN) 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[:CW] <FixedFreq>
[SENSe<Ch>:]FREQuency:FIXed <FixedFreq>
Defines the fixed (Continuous Wave, CW) frequency for all sweep types operating at
fixed frequency ("Time", "CW Mode"). The two command forms
[SENSe<Ch>:]FREQuency[:CW] and [SENSe<Ch>:]FREQuency:FIXed are
equivalent.
The frequency ranges are listed in Table 11-18.
Note:[SENSe<Ch>:]FREQuency[:CW]|:FIXed is equivalent to
SOURce<Ch>:FREQuency<PhyPt>[:CW]|:FIXed. Source and receiver frequency
are always equal; the four commands overwrite each other.
Suffix:
<Ch>
.
Channel number
Parameters:
<FixedFreq> Fixed stimulus and analyzer frequency
*RST: 1 GHz
Default unit: Hz
Example:
FUNC "XTIMe:POW:A1"
Activate a time sweep and select the wave quantity a
1
as mea-
sured parameter for channel and trace no. 1.
FREQ:CW 100MHz
Set the CW frequency to 100 MHz.
Manual operation: See "CW Frequency" on page 312
[SENSe<Ch>:]FREQuency:SBANd <Sideband>
Defines whether the analyzer measures with a local oscillator frequency LO below or
above the RF input frequency.
