Parameters:
<SettlingDelay> Settling delay
Default unit: s
Manual operation: See "Settling Delay / Reset Delay" on page 145
SOURce... (other)
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.
Parameters:
<PhysicalPort> Number of first/only physical port
Range: 1 to number of physical ports
<PhysicalPort> Number of second physical port (optional), forming a balanced
port with the first physical port.
The port numbers must be different. Moreover, a physical port
cannot be assigned to several logical ports.
Range: 1 to number of physical ports
Example:
*RST; :SOUR:LPOR1 1,2
Combine the physical ports 1 and 2 to the logical port 1 (bal-
anced)
SOUR:LPOR1?
Query the physical ports assigned to logical port no. 1. The
response is 1,2.
Manual operation: See "Select Predefined Port" on page 399
