Set to Default
Calls the default settings.
Parameter Value
"Number of Carriers" "1"
"Carrier Spacing" "0 MHz"
"Crest Factor Mode" "Off"
"Signal Period Mode" "Longest file wins"
Remote command:
[:SOURce<hw>]:BB:ARBitrary:MCARrier:PRESet on page 1047
Save/Recall Frame
Accesses the standard "Save/Recall" dialog, i.e. the standard instrument function for
storing and recalling the complete dialog-related settings. Refer to Chapter 11.4, "Sav-
ing and Recalling Instrument Settings", on page 679 for a detailed description.
The multi-carrier settings are saved as files with predefined file extension
*.arb_multcarr. The filename and the directory are user-definable.

Mode
Selects the way the carriers are distributed within the available bandwidth.
"Equidistant Carrier Spacing"
Sets an equidistant carrier spacing distribution, i.e. the carriers are
equally spaced and centered toward the RF frequency. The carrier
frequencies are automatically calculated depending on the selected
number of carriers and the carrier spacing.
"Arbitrary Carrier Frequency"
Enables the specification of the carrier frequency of each carrier indi-
vidually.
Remote command:
[:SOURce<hw>]:BB:ARBitrary:MCARrier:CARRier:MODE on page 1048
Number of Carriers
Sets the number of carriers for the multi-carrier waveform. By default the multi-carrier
table lists one carrier. A maximum of 512 carriers can be configured and activated.
When the number of carriers is increased, new lines are added at the end of the table.
If these carriers already have been defined before, the settings are preset according to
the former settings. Otherwise the parameters are preset with the default values.
See also Chapter 5.11.2.1, "Defining the Carrier Frequency", on page 383.
