Symbol Rate
Selects the symbol rate. The value range of this parameter depends on the selected
modulation type; the range is automatically redefined.
An error message appears if the selected symbol rate is outside of the redefined
range. The symbol rate is set automatically to the maximum allowed value for the new
modulation.
Remote command:
[:SOURce<hw>]:BB:DM:SRATe

Coding
Selects the coding (see Chapter 3.4.1.5, "Supported Coding Schemes" , on page 105).
The dialog shows only the coding settings that are permissible for the selected modula-
tion type and installed options (see
Table 3-8 ). All other coding methods are grayed
out.
A subsequent modification to a modulation type for which the selected coding is not
available, automatically disables the coding ("Coding = Off").
