SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]
<IntSourcePow>
Defines the power of the internal signal source (channel power). The setting is valid for
all sweep types except power sweep.
Tip:
Use
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 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 (
) and a port-specific power offset
(
Parameters:
<IntSourcePow>
Internal source power
Range:
-300 dBm to +200 dBm. The usable power range is
frequency-dependent; refer to the data sheet.
Increment: 0.1 dB
*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.
SOUR:POW2:SLOP 10
Set the power slope factor for the wave transmitted at port 2 to 10
dB/GHz. The internal source power and the waves at the other test
ports are not affected.
Manual operation:
See
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:OFFSet
<Offset>, <OffsetType>
Defines a port-specific source power or a power offset relative to the channel power (
). An addi-
tional "Cal Power Offset" can be defined via
.
Suffix:
<Ch>
.
Channel number
<PhyPt>
Test port number of the analyzer
