The menu is used to set the power ramping. Control signals "Burst" and "Lev_Att" are
used to control power ramping (see chapter 5.8.2.6.1, "Power Ramping and Level Attenu-
ation", on page 335).
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 - Power Ramp Control - Digital Modulation
Enables/disables power ramping.
SCPI command:
[:SOURce<hw>]:BB:DM:PRAMp[:STATe] on page 644
Source - Power Ramp Control - Digital Modulation
Enters the source for the power ramp control signals.
"Internal"
The control signals in the internal control list are used for control purpo-
ses.
The signals are output on the LEV_ATT and BURST pin on the AUX I/O
interface of path A.
In the case of two-path instruments, the path B signal can be placed on
one of the USER interfaces.
"External Digital
"
The control signal is fed in via the AUX I/O interface.
For two-path instruments, path A = LEV-ATT pin, path B = user-definable
USER pin or USER connector.
SCPI command:
[:SOURce<hw>]:BB:DM:PRAMp:SOURce on page 644
Ramp Function - Digital Modulation
Enters the form of the transmitted power, i.e. the shape of the rising and falling edges
during power ramp control.
"Linear"
The transmitted power rises and falls linear fashion.
