SCPI, Command
Types
Device-specific, command or query
Example:
LOM1 OFF; LOR1 OFF
Switch the local oscillators for the measurement channel b and the reference
channel a at port no. 1 off.
[SENSe<Ch>:]LPORt...
This subsystem defines the reference impedances of the balanced ports.
[SENSe<Ch>:]LPORt<log_port>:ZCOMmon <real>[, <imaginary>]
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>
<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
25 Ω (real impedance)

Types
Device-specific, command or query
Example:
*RST; :CALC:PAR:DEL 'TRC1'
Reset the analyzer and delete the (default) trace for channel
no. 1.
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.
[SENSe<Ch>:]LPORt<log_port>:ZDIFferent <real>[, <imaginary>]
Specifies the complex differential mode reference impedance for the balanced (logical) port numbered
<log_port>.
