power (SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]).
Suffix:
<Ch>
.
Channel number
<PhyPt> Test port number of the analyzer. This suffix is ignored; the gen-
erator is selected via <Gen>.
<Gen> Generator number
Parameters:
<Offset> Port-specific power offset
Range: -300 dB to +300 dB (adjust to the generator's actual
source power range and the test setup)
Increment: 0.01 dB (other values are rounded)

SYST:COMM:RDEV:GEN2:DEF 'Ext. Gen. 2', 'SME02',
'gpib0', '22'
Configure an R&S SME02 generator as external generator no.
1, assigning the name "Ext. Gen. 1" and a GPIB address 21.
Configure a second R&S SME02 generator, assigning the name
"Ext. Gen. 2" and a GPIB address 22.
