measurement is switched off.
When performing a power calibration at all selected intermodulation orders, the command
SOURce<Ch>:POWer<Pt>:CORRection:IMODulation:SPORts[:ACQuire] should be used which
combines steps 1 and 2 of the legacy power calibration into one step.
When the upper tone source is an external generator
([SENSe<Ch>:]FREQuency:IMODulation:UTONe) and Port 1 is selected as Two Tone Output
([SENSe<Ch>:]FREQuency:IMODulation:TTOutput) the source calibration for the upper tone port
must not use any reference receiver. If the source power settings are not set accordingly before calling
this command an error will be returned.
<Ch>
Channel number
<pt>
Port number This suffix is ignored; the analyzer calibrates the port that is selected as
source port for the upper tone of the intermodulation measurement
([SENSe<Ch>:]FREQuency:IMODulation:UTONe).

Example:
See SOURce<Ch>:POWer<Pt>:CORRection:IMODulation:LTONe[:ACQuire]
SOURce<Ch>:POWer<Pt>: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 (Cal Power Offset). The value has no impact on the source
power.

Types
Device-specific, command or query
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 power levels 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
