SOURce<Ch>:POWer<PhyPt>:CORRection:GENerator<Gen>:LEVel:OFFSet
<Offset>
Specifies a gain (positive values) or an attenuation (negative values) in the signal path
between the external generator and the calibrated reference plane. The value has no
impact on the generator power.
Suffix:
<Ch>
.
Calibrated channel number
<PhyPt>
Calibrated port number. This suffix is ignored; the generator is
selected via
<Gen>
.
<Gen>
Generator number
Parameters:
<Offset>
Gain or attenuation value
Range:
-300 dB to +300 dB (adjust to the test setup)
Increment: 0.01 dB (other values are rounded)
*RST:
0 dB
Default unit: dB
Example:
Assume that a DUT requires a constant input power of +35 dBm
at its port 2, and that the measurement path contains an ampli-
fier with a 30 dB gain.
SYST:COMM:RDEV:GEN1:DEF 'Ext. Gen. 1', 'SME02',
'gpib0', '21'
Configure an R&S SME02 generator as external generator no.
1, assigning the name Ext. Gen. 1 and a GPIB address 21.
SOUR:POW:GEN1:OFFS 5, ONLY
Set the source power of generator no. 1 to +5 dBm.
SOUR:POW:CORR:GEN1:LEV:OFFS 30
Specify the gain of the amplifier in the signal path between the
external generator and the input port of the DUT.
SOUR:POW:CORR:ACQ GEN,1
Perform a source power calibration using the external generator
no. 1 as a source port and the target power of +35 dBm.
Manual operation:

SOURce<Ch>:POWer<PhyPt>:CORRection:LEVel:OFFSet
<Offset>
Specifies a gain (positive values) or an attenuation (negative values) in the signal path
between the source port and the calibrated reference plane. The value has no impact
on the source power.
Suffix:

Calibrated channel number
<PhyPt>
