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 384
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
Parameters:
<Offset> Port-specific power offset
Range: -300 dB to +300 dB (adjust to the analyzer's actual
source power range and the test setup)
Increment: 0.01 dB (other values are rounded)
*RST: 0 dB
Default unit: dB
<OffsetType> ONLY | CPADd
ONLY - only the port-specific power is used; the channel power
is ignored.
CPADd - the port-specific power is added as an offset to the
channel power.
*RST: CPADd
Example:
*RST; SOUR:POW -6
Reset the instrument, activating a frequency sweep and set the
internal source power (channel power) for the default channel 1
to -6 dBm.
SOUR:POW1:OFFS 6, ONLY; SOUR:POW2:OFFS 6, CPAD
Replace the source power at port 1 by +6 dBm, the source
power at port 2 by 0 dBm. The powers at the remaining ports (if
available) are not affected.
Manual operation: See "Port Overview" on page 491
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:SLOPe <Slope>
Defines a linear factor to modify the internal source power at port <PhyPt> as a func-
tion of the stimulus frequency.
