(POWER RAMP
CONTROL...)
RAMP FUNCTION
Selection of shape of rising and falling ramp for
envelope control.
LIN
Linear ramp function.
COS
Cosine function. A more favourable
spectrum than that of the LIN function is
obtained.
IEC/IEEE-bus
SOUR:GSM:PRAM:SHAP LIN
RAMP DELAY
Input value for a shift of the envelope characteristic
to the modulated signal. A positive value causes a
delay of the envelope. The values are set in the units
of the symbol length.
IEC/IEEE-bus
SOUR:GSM:PRAM:DEL 0.1
RISE OFFSET
Input value for a positive or negative offset of the
rising ramp of the envelope at the beginning of a slot.
IEC/IEEE-bus
SOUR:GSM:PRAM:ROFF -1
FALL OFFSET
Input value for a positive or negative offset of the
falling ramp of the envelope at the end of a slot.
IEC/IEEE-bus
SOUR:GSM:PRAM:FOFF 1
SLOT ATTENUATION
Input value in dB for the level reduction of all active slots whose SLOT LEVEL
was set to ATTEN. Menu SELECT SLOT allows the slots to be determined
whose level is to be reduced.
IEC/IEEE-bus command
SOUR:GSM:SLOT:ATT 40 DB
SAVE/RCL FRAME...
Opens a window for saving and loading a frame configuration. Loading a
frame affects all parameters that can be set under SELECT SLOT.
