The dialog comprises the settings used to configure the power ramping, like the source
of the control signals, the form of the ramp function and the applied attenuation.
See also "Power Ramping and Level Attenuation" on page 92.
Power ramping is possible up to a symbol rate of 5 MHz. A higher symbol rate disables
the power ramping automatically and an error message is output.

State
Enables/disables power ramping.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp[:STATe] on page 725
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 3.5.4.1, "How to Create and Assign a Control List",
on page 134.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:SOURce on page 723
Ramp Function
Selects the ramp function that describes the shape of the rising and falling edges dur-
ing power ramp control, see Figure 3-3.
"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 723
Ramp Time
Enters the power ramping rise time and the fall time for a burst. The setting is
expressed in symbols. See also Figure 3-3.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:TIME on page 723
