#### [SENSe<Ch>:]PORt...

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] | 1mW to 10 MW for the real part [W] – 10 MW to 10 MW for the imaginary part [W]
*RST value | Default reference impedance of the connector family assigned to the port (real impedance, e.g. 50 W).
SCPI, Command Types | Device-specific, command or query
Example: | POR2:ZREF 52, 2 Specify a complex reference impedance of 52 W + j * 2 W for the (physical) port no. 2.
