[SENSe<Ch>:]PORT...    Related Topics  

This subsystem controls the frequency reference oscillator.

[SENSe<Ch>:]PORT<phys_port>:ZREFerence <real>[, <imaginary>]

Specifies the complex reference impedance for the physical port numbered <phys_port>.

<Ch>

Channel number. If unspecified the numeric suffix is set to 1.

 

<phys_port>

Physical port number. The number of ports depends on the analyzer model.

 

<real>
<imaginary>

Real and imaginary part of the port impedance. <imaginary> may be omitted to define a real impedance.

Range [def. unit]

1mΩ to 10 MΩ for the real part [Ω]
–10 MΩ to 10 MΩ for the imaginary part [Ω]

*RST value

Default reference impedance of the connector family assigned to the port (real impedance, e.g. 50 Ω).

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.
