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.
With option R&S ZNB/ZNBT-K4, Frequency Conversion Measurements, port-specific
source and receiver frequencies can be defined; see SOURce<Ch>:
FREQuency<PhyPt>:CONVersion:ARBitrary:IFRequency.
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 386
[SENSe<Ch>:]FREQuency:CENTer <CenterFreq>
Defines the center of the measurement and display range for a frequency sweep
(sweep range). The default center frequency is the center of the analyzer's maximum
frequency range: (f
MIN
+ f
MAX
)/2. The range depends on the instrument model; see
Table 8-16.
Suffix:
<Ch>
.
Channel number
Parameters:
<CenterFreq> Center frequency of the sweep
Increment: 0.1 kHz
Default unit: Hz
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 385
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>).
