SOURce<Ch>:FREQuency<PhyPt>[:CW] <FixedFreq>
SOURce<Ch>:FREQuency<PhyPt>:FIXed <FixedFreq>
Defines the fixed (Continuous Wave, CW) frequency for all sweep types operating at
fixed frequency ("Power", "Time", "CW Mode"). The two command forms
SOURce<Ch>:FREQuency<PhyPt>:CW and
SOURce<Ch>:FREQuency<PhyPt>:FIXed are equivalent.
The frequency range depends on the R&S ZNB/ZNBT model; see Chapter 8.3.14,
"[SENSe:] Commands", on page 1113.
Note:SOURce<Ch>:FREQuency<PhyPt>[:CW]|:FIXed is equivalent to
[SENSe<Ch>:]FREQuency[: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
<PhyPt> Test port number of the analyzer. This suffix is ignored because
the selected frequency applies to all source ports in the active
channel.
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 385
SOURce<Ch>:FREQuency<PhyPt>:CONVersion:ARBitrary:EFRequency<Gen>
<Boolean>, <Numerator>, <Denominator>, <Offset>, <SweepType>
Defines an external generator frequency for frequency-converting measurements. The
external generator frequency is either a range (for frequency sweeps) or a CW fre-
quency (for power, time and CW Mode sweeps).
Suffix:
<Ch>
.
Channel number
<PhyPt> Test port number of the analyzer. This suffix is ignored because
the generator is referenced via <Gen>.
