BB:DM:SOUR DLIS
the internal data generator is used.
BB:DM:DLIS:SEL 'test'
the data list test.dm_iqd is used.
Example:
[:SOURce<hw>]:BB:DM:SRATe <Srate>
The command sets the symbol rate. The value range is dependent on the selected mod-
ulation type. On changing to an FSK modulation type, excessively high values are auto-
matically limited to the maximum value that can be set for FSK (see data sheet). The
symbol rate can be entered in Hz/kHz/MHz or Symb/s / kSymb/s and MSymb/s.
When a standard is selected (DM:STANdard), the symbol rate is automatically set to the
appropriate default value.
The value range is dependent on the selected modulation type (:BB:DM:FORM). When a
standard is selected (:BB:DM:STAN), the symbol rate is set to the default value.

Default unit:
BB:DM:SRAT 10 MHz
sets a symbol rate of 10 MHz.
Example:
[:SOURce<hw>]:BB:DM:STANdard <Standard>
The command selects the standard. After selection, modulation parameters "Modulation
Type" (:BB:DM:FORMat), "Symbol Rate" (:BB:DM:SRATe), "Filter"
(:BB:DM:FILTer:TYPE and :BB:DM:FILTer:PARameter:...) and "Coding"
(:BB:DM:CODing) are automatically set in accordance with the standard. The USER
parameter cannot be set. A query returns this value if a user-defined Custom Dig Mod
setting was loaded or if one of the associated settings was changed subsequent to the
selection of a standard. The user defined settings are stored and loaded with com-
mands :BB:DM:STAN:ULIS:... (see chapter 7.15.3.3.2, "DM Lists", on page 645).
