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.
