function and the applied attenuation (see also "Power Ramping and Level Attenuation"
on page 321).
Power ramping is possible up to a symbol rate of 5 MHz. If a higher symbol rate is set,
power ramping is automatically switched off and an error message is output.
State
Enables/disables power ramping.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp[:STATe]
on page 653
Source
Enters the source for the power ramp control signals.
"Internal" The control signals in the internal control list are used for control pur-
poses.
See also
"Control and Marker List Editor" on page 354.
The signals are output on the LEV_ATT and BURST pin on the AUX
I/O interface of path A.
"External Digi-
tal " The control signal is fed in via the AUX I/O interface.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:SOURce

Ramp Function
Selects the ramp function that describes the shape of the rising and falling edges dur-
ing power ramp control, see
Figure 5-25 .
"Linear" The transmitted power rises and falls linear fashion.
"Cosine" The transmitted power rises and falls with a cosine-shaped edge.
This gives rise to a more favorable spectrum than the "Linear" setting.
