SOURce<Ch>:POWer<PhyPt>:STOP
............................................................................1134
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude] <IntSourcePow>
Defines the power of the internal signal source (channel base power). The setting is
valid for all sweep types, except power sweep.
Tip: Use
SOURce<Ch>:POWer<PhyPt>:STARt
and
SOURce<Ch>:POWer<PhyPt>:
STOP
to define the sweep range for a power sweep.
Suffix:
<Ch>
.
Channel number
<PhyPt> Test port number of the analyzer. This suffix is ignored because
the selected channel base 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<PhyPt>[:LEVel][:IMMediate]:SLOPe
) and a port-
specific power offset (
SOURce<Ch>:POWer<PhyPt>[:
LEVel][:IMMediate]:OFFSet
).
Parameters:
<IntSourcePow> Internal source power
Range:
The usable power range is frequency-dependent;
refer to the data sheet.
*RST: -10 dBm
Default unit: dBm
Example: FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as mea-
sured parameter for channel and trace no. 1.
SOUR:POW -6
Set the internal source power for channel 1 to -6 dBm.
Manual operation: See "Power" on page 385
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:OFFSet <Offset>, <OffsetType>
Defines a port-specific source power or a power offset relative to the channel power
(
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]
). An addi-
tional "Cal Power Offset" can be defined via
SOURce<Ch>:POWer<PhyPt>:
CORRection:LEVel:OFFSet
.
Suffix:
<Ch>
.
Channel number
<PhyPt> Test port number of the analyzer
