This subsystem defines the reference impedances of the balanced ports.
Command tree: [SENSe<Chn>:]LPORt<log_port>
Specifies the complex common mode reference impedance for the balanced (logical) port numbered <log_port>.
<Ch> |
Channel number. If unspecified the numeric suffix is set to 1.
|
<log_port> |
Logical port number. The logical ports must be defined using SOURce<Ch>:LPORt<log_port> <phys_port1>,<phys_port2>. An n port analyzer supports a maximum of n/2 (n even) or (n – 1)/2 (n odd) logical ports.
|
<real> |
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] |
*RST value |
25 Ω (real impedance)
|
SCPI, Command Types |
Device-specific, command or query
|
Example: |
SOUR:LPOR1 1,2 Combine the physical ports no. 1 and 2 to define the balanced (logical) port no. 1. LPOR1:ZCOM 27, 2 Specify a complex common mode reference impedance of 27Ω + j * 2Ω for the defined port.
|
Specifies the complex differential mode reference impedance for the balanced (logical) port numbered <log_port>.
<Ch> |
Channel number. If unspecified the numeric suffix is set to 1.
