[SENSe<Ch>:]SWEep:AXIS:POWer '<power_ref>'
Selects the stimulus signal that is used for the definition of the power sweep range or fixed power.
This command is particularly useful in arbitrary mode (with option R&S ZVA-K4), where the
frequencies and source power levels at the ports are independent. For R&S ZVA analyzers without option
R&S ZVA-K4, all power levels are coupled so that this selection has no effect.
<Ch>
Channel number.
'<frequency_ref>'
String parameter, one of the following signals:
'Channel Base; Source' – Base channel power
'Port 1; Source' – Source power at port 1,
'Port 2; Source' – Source power at port 2
...
'Gen 1; Source' – External generator power 1
...
*RST value
'Channel Base; Source'

Types
Device-specific, command or query
Example:
*RST; SOUR:POW 5
Define a base channel power of +5 dBm. This power is also used as an
(initial) power for all test ports and external generators.
SOUR:POW1:OFFS -5, CPAD
Change the source power at test port no. 1 to 0 dB without affecting the power
at the remaining ports.
SWE:AXIS:POW 'Port 1; Source'
Select the source signal at port 1 as the reference signal for power definitions.
SOUR:POW -5
Shift all power levels by -5 GHz.
SWE:AXIS:POW 'Port 2; Source'
Select the source signal at port 2 as the reference signal for power definitions.
SOUR:POW?
Query the power at test port 2. The response is 0.
