In addition to the test ports ("Port"), the source ports include all configured external
generators ("Gen"). Each port is displayed with its port number and device type ("Info").
For each port, the available power range and resulting port power are calculated from
the configured power conversion and source attenuation settings.
Power Conversion
Opens a dialog that allows you to define a port-specific source power range (for power
sweeps) or fixed power (for frequency, time and CW mode sweeps) for the current
channel. See "Modify Cal Power dialog" on page 567.
In the default configuration, the channel base power P
b
is used. The frequency-adjus-
ted result is displayed in the "Power Result" column.
Slope
Defines a linear factor to modify the port-specific source power as a function of the
stimulus frequency. The resulting output power at port frequency f is calculated as
<Power Result> + <Slope> * f.
Remote command:
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:SLOPe
Modify Cal Power dialog
The "Modify Cal Power" dialog allows you to define port-specific source powers, which
can be necessary to ensure a definite signal power at the inputs of the DUT.
Access: Port Settings dialog > "Arbitrary Power" tab > "Power Conversion" cells
Dependencies
Gen ports driven by the same internal source (R&S ZNBT only) must use the same
port power formula. The analyzer firmware enforces the alignment of formulas.
Related information
The settings in the "Modify Cal Power" dialog are also used to define the target power
for the scalar power calibration; refer to Chapter 5.11.3.2, "Modify Cal Power dialog",
on page 527.
The diagram in the center of the dialog visualizes the settings and results below.
