SOURce<Ch>:LPORt<log_port>:CLEar [ALL]
Dissolves a balanced port numbered <log_port> or all balanced ports.
<Ch> Channel number.
<log_port> Logical port number used to number balanced ports. If unspecified the
numeric suffix is set to 1.
Range [def.
unit]
Range according to the current port configuration
(
SOURce<Ch>:LPORt<log_port>
). If an undefined balanced port
number is used, the analyzer generates an error message. Exception:
Parameter
ALL
, see below. [–]
ALL
If
ALL
is specified, all balanced ports are dissolved; the <log_port>
suffix is ignored. If
ALL
is omitted, only the specified balanced port is
dissolved.

SOURce<Ch>:POWer...
This subsystem controls the power of the internal signal source and provides output port settings.
Note: The SOURce<Ch>:POWer... subsystem comprises port-specific and general settings. Port-
specific settings are valid for the port specified by the numeric suffix
<Pt>
(...
:POWER<Pt>:
...).
General settings are valid for all test ports of the analyzer; the port suffix is ignored. Refer to the
description of the individual commands for more information.
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude] <numeric_value>
Defines the power of the internal signal source (channel power). The setting is valid for all sweep types
except power sweep.
Use
SOURce<Ch>:POWer<Pt>:STARt
and
SOURce<Ch>:POWer<Pt>:STOP
to define the
sweep range for a power sweep.
<Ch> Channel number.
<Pt> Test port number of the analyzer. This suffix is ignored because the
selected channel power applies to all source ports used in the
active channel. It is possible though to define a port-specific slope
factor for the source power
(
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate]:SLOPe
).
Moreover, it is possible to define a port-specific power offset
(
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate]:OFFSet
).
<numeric_value> Internal source power.
Range [def. unit] –40 dBm to +10 dBm. The exact range depends on the analyzer
model; refer to the data sheet [dBm]. UP and DOWN
increment/decrement the source power in 0.1-dB steps.
*RST value 0 dBm
