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:
<Ch>
.
Calibrated channel number
<PhyPt>
Calibrated port 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 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.
