Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:TIME on page 673
Rise Delay
Sets the offset in the rising edge of the envelope at the start of a burst, see Fig-
ure 5-23.
A positive value gives rise to a delay (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 672
Fall Delay
Sets the offset in the falling edge of the envelope at the end of a burst, see Fig-
ure 5-23.
A positive value gives rise to a delay, 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 672
Attenuation
Determies the level by that the average singal level is attenuated during the signal
attenuation period, during the time the "Lev_Att" signal is high. See also Figure 5-22.
For information about the required control signal LEV_ATT, refer to "Power Ramping
and Level Attenuation" on page 333.
The LEV_ATT control signal is defined in the "Control Data Editor".
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:ATTenuation on page 671
Baseband Only
Restricts power ramping to the baseband signal.
"Off"
Level attenuation is effected via the attenuator stages in the RF sec-
tion; only the remaining part is attenuated in the baseband. The sig-
nal is issued at the RF output with the defined level values.
"On"
Level attenuation is effected in the baseband only.
This setting is mandatory in the following cases: When only the base-
band signal is issued at the I/Q outputs. It is thus ensured that, with
power ramping active, this signal is output with the defined level val-
ues.
Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:BBONly[:STATe] on page 671
Trigger/Marker/Clock
The "Trigger/Marker/Clock" dialogis accessed via the "Custom Digital Modulation" main
menu.
