291Operating Manual 1407.0806.32 ─ 13
Parameters:
<State> 0 | 1 | OFF | ON
*RST: 0
Example:
AM:STAT ON
activates AM modulation.
Manual operation: See "State" on page 170
[:SOURce<hw>]:AM:TYPE <AmType>
Selects exponential or linear amplitude modulation.
Exponential amplitude modulation is available for instruments, equipped with 12 GHz or
higher frequency options. For more details, see also the GUI reference chapter 5.4.2,
"Amplitude Modulation (AM)", on page 169.
Parameters:
<AmType> LINear | EXPonential
*RST: LINear
Example:
AM:TYPE EXP
activates the exponential amplitude modulation.
Options: (exponential): R&S SMB-B112/112L/120/120L/140/140L
Manual operation: See "AM Type" on page 170
7.12.2 SOURce:CORRection Subsystem
The output level is corrected in the CORRection subsystem. Correction is performed by
user-defined table values being added to the output level for the respective RF frequency.
In the R&S SMB, this subsystem is used to select, transfer and activate user correction
tables.
Each list is stored as a file. The name of the user correction file can be freely selected.
The file extension *.uco is assigned automatically and cannot be changed.
The files can be stored in a freely selectable directory and opened from there. The default
directory is set using command :MMEMory:CDIRectory on page 270. In the case of
files which are stored in the default directory, only the file name has to be specified in
commands. Otherwise, the complete absolute path has to be specified with every com-
mand. The extension can be omitted in any case.
In the following command examples, the files are stored in the default directory.
The amplitude can also be linearized automatically by means of a R&S NRP power sen-
sor connected to the generator output signal. With the aid of the command [:
SOURce<hw>]:CORRection:CSET:DATA[:SENSor<ch>][:POWer]:SONCe, a list
with correction values for external test assemblies can be automatically determined, e.g.
