[SENSe:]LPORt...
The
[SENSe:]LPORt...
commands define the reference impedances of the bal-
anced ports.

[SENSe<Ch>:]LPORt<LogPt>:ZCOMmon
<RealPart>[, <ImaginaryPart>]
[SENSe<Ch>:]LPORt<LogPt>:ZDIFferent
<RealPart>[, <ImaginaryPart>]
These commands specify the complex common mode and differential mode reference
impedances for the balanced (logical) port numbered
<LogPt>
.
Use
[SENSe<Ch>:]LPORt<LogPt>:ZDEFault[:STATe]
to toggle between config-
ured and default reference impedances.
Suffix:
<Ch>
.
Channel number
<LogPt>
Logical port number. The logical ports must be defined using
<PhysicalPort1>,
<PhysicalPort2>
. An n port analyzer supports a maximum of
n/2 (n even) or (n - 1)/2 (n odd) logical ports.
Parameters:
<RealPart>
Real part of the port impedance.
Range:
1 mΩ to 10 MΩ
*RST:
ZCOMmon: 25 Ω; ZDIFferent: 100 Ω (real impedan-
ces)
Default unit: Ohm
<ImaginaryPart>
Imaginary part of the port impedance; may be omitted to define
a real impedance.
Range:
- 10 MΩ to 10 MΩ
*RST:
0 Ω (real impedances)
Default unit: Ohm
