the power control locks and tries to achieve the target level. Readings outside the
range are not considered.

Delay Time
Defines a waiting period between the level adjustment of the generator and the next
measurement of the power sensor.
With this parameter, you compensate any dead times in the controlled system.
Remote command:
[:SOURce<hw>]:POWer:SPC:DELay
on page 793
Use Peak Power
Activates control by means of the peak power values, provided the power sensor sup-
ports this function. Otherwise, the dialog does not show this parameter.
Remote command:
[:SOURce<hw>]:POWer:SPC:PEAK
on page 793
Use SParameter - Power Sensors
Activates the use of the S-Parameter correction data of the connected power sensor.
For sensors with attenuator this checkbox is automatically checked.
Refer to the manual of the connected R&S NRP-Zxx power sensor for a description on
how to use the SParameter table.

5.5.9 User Correction
The "User Correction" function is used to create and activate lists in which level correc-
tion values predefined by the user are freely assigned to RF frequencies. Correction is
performed by the user-defined table values being added to the output level for the
respective RF frequency.
With frequencies which are not contained in the list, the level correction is determined
by interpolation of the closest correction values.
The lists are created in the "List Editor". Each list is stored in its own file with the prede-
fined file extension
*. uco
. The name of the User Correction file can be freely
selected. The files are loaded from the "Lists..." file manager. Externally created tables
with pairs of frequency and level values can be converted into User Correction files
using the import function. The external files must have the file extension
*.txt
or
*.csv
. These file formats are provided e.g. by the Microsoft Excel program. The sepa-
rators for table columns and for decimal floating-point numerals can be set. In addition,
internally created User Correction data can be exported into ASCII files using the
export function.
The amplitude can also be linearized automatically by means of an R&S NRP power
sensor connected to one of the generator output signals. With the aid of the "Fill with
