Remote command:
[:SOURce<hw>]:BB:DM:PRAMp[:STATe] on page 905
Source
Defines the source for the power ramp control signals.
"Internal"
The control signals as defined in the internal control list are used for
control purposes.
See also Chapter 4.6.4.1, "How to Create and Assign a Control List",
on page 286.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:SOURce on page 903
Ramp Function
Selects the ramp function that describes the shape of the rising and falling edges dur-
ing power ramp control, see Figure 4-4.
"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 903
Ramp Time
Enters the power ramping rise time and the fall time for a burst. The setting is
expressed in symbols. See also Figure 4-4.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:TIME on page 903
Rise Delay
Sets the offset in the rising edge of the envelope at the start of a burst, see Figure 4-4.
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 903
Fall Delay
Sets the offset in the falling edge of the envelope at the end of a burst, see Figure 4-4.
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 903
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 4-3.
For information about the required control signal, refer to "Power Ramping and Level
Attenuation" on page 232.
