SOURce<Ch>:RLO:POFFset <Value>
Defines the power offset of the the (optional) rear LO Out port for channel <Ch>.
If SOURce<Ch>:RLO:PABSolut on page 1417 is OFF, then the output power is equal
to the channel base power f
b
plus the power offset. Otherwise the output power is set
to the fixed power offset.
Suffix:
<Ch>
.
Channel number
Parameters:
<Value> Offset value in dB
Options: R&S ZNA-B8
Manual operation: See "Port Power Offset" on page 576

SOURce:LPORt...
The SOURce:LPORt... commands define the logical port configuration (balanced
ports, renumbered single-ended ports).

SOURce<Ch>:LPORt<LogPt> <PhysicalPort>[, <PhysicalPort>]
Assigns the logical port number <LogPt> either to the single-ended physical port
<PhysicalPort1> or to a pair of physical ports <PhysicalPort1>,<PhysicalPort2>, at the
same time defining them as balanced port.
Important:
●
All required logical ports (balanced and single ended) must be created explicitly.
●
A balanced port configuration generally introduces a new set of mixed mode mea-
sured quantities. Therefore the traces must be redefined when a balanced port is
created. To avoid any inconsistencies the analyzer deletes all traces when
SOURce<Ch>:LPORt<LogPt> is used.
●
It is essential to complete the logical port assignment before defining other port
properties such as common or differential mode impedances: whenever a logical
port is created using SOURce<Ch>:LPORt<LogPt>, the parameters of all existing
logical ports are reset.
Suffix:
<Ch>
.
Channel number.
<LogPt> Identifying number of the newly created balanced or single-
ended logical port.
Must be between 1 and the number of physical ports (see
INSTrument:TPORt:COUNt?). If unspecified the numeric suf-
fix is set to 1.
