SOURce<Ch>:LOTRack:DFRequency?
If LO tracking is active in channel <Ch> (SOURce<Ch>:LOTRack[:STATe] ON), this

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.
