SCPI, Command
Types Confirmed, command or query
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as
measured parameter for channel and trace no. 1.
SOUR:POW -6
Set the internal source power for channel 1 to -6 dBm.
SOUR:POW2:SLOP 10
Set the power slope factor for the wave transmitted at port 2 to 10
dB/GHz. The internal source power and the waves at the other test
ports are not affected.
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate]:OFFSet <numeric_value>, ONLY |
CPADd
Defines a port-specific source power or a power offset relative to the channel power
(
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude]
). An additional Cal Power
Offset can be defined via
SOURce<Ch>:POWer<Pt>:CORRection:LEVel:OFFSet
.
<Ch> Channel number.
<Pt> Test port number of the analyzer.
<numeric_value> Port-specific power offset.
Range [def. unit] –300 dB to +300 dB [dB]. UP and DOWN increment/decrement
the phase in 1-dB steps.
*RST value 0 dB
Offset parameters
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 value CPADd
SCPI, Command
Types Confirmed (with additional device-specific character data
parameters), command or query
Example:
*RST; SOUR:POW -6
Reset the instrument, activating a frequency sweep and set the
internal source power (channel power) for the default channel 1
to -6 dBm.
SOUR:POW1:OFFS 6, ONLY; SOUR:POW2:OFFS 6, CPAD
Replace the source power at port 1 by +6 dBm, the source power
at port 2 by 0 dBm. The powers at the remaining ports (if
available) are not affected.
