7.3.14.11 [SENSe:]LPORt...

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

anced ports.

[SENSe<Ch>:]LPORt<LogPt>:ZCOMmon...................................................................... 1288

[SENSe<Ch>:]LPORt<LogPt>:ZDIFferent.......................................................................1288

[SENSe<Ch>:]LPORt<LogPt>:ZDEFault[:STATe].............................................................1289

[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

SOURce<Ch>:LPORt<LogPt> <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
