User Manual 1173.9163.02 ─ 38
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 port 2, and that the measurement path contains an amplifier
with a 30 dB gain.
*RST; SOUR:POW 0
Reset the instrument and set the internal source power (base
channel power) for the default channel 1 to 0 dBm.
SOUR:POW2:OFFS 5, ONLY
Replace the source power at port 2 by +5 dBm. The powers at
the remaining ports are not affected.
SOUR:POW2:CORR:LEV:OFFS 30
Specify the gain of the amplifier in the signal path between the
analyzer port 2 and the input port of the DUT.
SOUR:POW:CORR:ACQ PORT,2
Perform a source power calibration using port 2 as a source port
and the target power of +35 dBm.
Manual operation:
See
SOURce<Ch>:POWer<PhyPt>:GENerator<Gen>:OFFSet
<Offset>, <Mode>
Defines the power of an external generator or its power offset relative to the channel
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)
*RST:
0 dB
Default unit: dB
<Mode>
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
