"Internal"
The control signals as defined in the internal control list are used for
control purposes.
See also Chapter 5.6.4.1, "How to Create and Assign a Control List",
on page 285.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:SOURce on page 1002
Ramp Function
Selects the ramp function that describes the shape of the rising and falling edges dur-
ing power ramp control, see Figure 5-4.
"Linear"
The transmitted power rises and falls linear fashion.
"Cosine"
The transmitted power rises and falls with a cosine-shaped edge,
resulting in a more favorable spectrum than the "Linear" setting.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:SHAPe on page 1002
Ramp Time
Enters the power ramping rise time and the fall time for a burst. The setting is
expressed in symbols. See also Figure 5-4.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:TIME on page 1002
Rise Delay
Sets the offset in the rising edge of the envelope at the start of a burst, see Figure 5-4.
A positive value delays (the envelope length decreases) and a negative value causes
an advance (the envelope length increases). The setting is expressed in symbols.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:RDELay on page 1003
Fall Delay
Sets the offset in the falling edge of the envelope at the end of a burst, see Figure 5-4.
A positive value delays (the envelope length increases) and a negative value causes
an advance (the envelope length decreases). The setting is expressed in symbols.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:FDELay on page 1003
Attenuation
Determines the level by that the average signal level is attenuated during the signal
attenuation period, during the time the "Lev_Att" signal is high. See also Figure 5-3.
For information about the required control signal, refer to "Power Ramping and Level
Attenuation" on page 229.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:ATTenuation on page 1003
In Baseband Only
Restricts power ramping to the baseband signal.
