[: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.
Parameters:
<SRate>
float
Range:
400Hz to 15MHz (FSK) / 25 MHz
Increment: 0.001Hz
*RST:
270833kHz
Default unit: Hz
Example:
BB:DM:SRAT 10 MHz
sets a symbol rate of 10 MHz.
[: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

Example:
BB:DM:STAN DECT
selects digital modulation according to the DECT standard.
[:SOURce<hw>]:BB:DM:STATe
<State>
The command enables or disables digital modulation. Switching on digital modulation
turns off all the other digital standards.
