User Manual 1173.9557.02 ─ 13
Parameters:
<Offset>
Port-specific power offset
Range:
-300 dB to +300 dB (adjust to the analyzer's actual
source power range and the test setup)
Increment: 0.01 dB (other values are rounded)
*RST:
0 dB
Default unit: dB
<OffsetType>
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 chan-
nel power.
*RST:
CPADd
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.
Manual operation:
See
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:SLOPe
<Slope>
Defines a linear factor to modify the internal source power at port
<PhyPt>
as a function
of the stimulus frequency.
Suffix:
<Ch>
.
Channel number
<PhyPt>
Test port number of the analyzer
Parameters:
<Slope>
Port-specific slope factor
Range:
-40 dB/GHz to +40 dB/GHz. The resulting power
range over the entire frequency sweep must be within
the power range of the analyzer; refer to the data
sheet.
Increment: 0.1-dB/GHz
*RST:
0 dB/GHz
Default unit: DB/GHZ
