<ImaginaryPart> Imaginary part of the port impedance. This part may be omitted
to define a real impedance.
Range: - 10 MΩ to 10 MΩ
*RST: Default reference impedance of the connector fam-
ily assigned to the port (real impedance, e.g. 50 Ω).
Default unit: Ohm
Example:
PORT2:ZREF 52, 2
Specify a complex reference impedance of 52 Ω + j * 2 Ω for the
(physical) port no. 2.
CALC:TRAN:IMP:RNOR PWAV
Select renormalization of port impedances according to the
power waves theory.
Manual operation: See "Single Ended Mode / Common Mode / Differential Mode"

SOURce commands
The SOURce... commands affect the source settings of the R&S ZNL/ZNLE.
Port-specific and general settings
The SOURce... subsystem comprises channel-specific and general settings. Chan-
nel-specific settings are valid for the channel specified by the numeric suffix <Ch>
(SENSe<Ch>:...). General settings are valid for all channels; the channel suffix is
ignored. Refer to the description of the individual commands for more information.
SOURce:FREQuency...
The SOURce:FREQuency... commands configure the sources for frequency conver-
sion measurements and control the frequency and power of the internal signal source.

SOURce<Ch>:FREQuency<PhyPt>:FIXed.......................................................................973
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 ("Time", "CW Mode"). The two command forms
SOURce<Ch>:FREQuency<PhyPt>:CW and
SOURce<Ch>:FREQuency<PhyPt>:FIXed are equivalent.
The frequency ranges are listed in Table 11-18.
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.
