(POWER RAMP
CONTROL...)
SET DEFAULT
Resets the subsequent parameters to the factory-set
values.
IEC/IEEE-bus
:SOUR:NADC:PRAM:PRES
RAMP TIME
Input value for the rise and fall time of the envelope
at the beginning or end of a slot. The time is set in
units of symbol period.
IEC/IEEE-bus
:SOUR:NADC:PRAM:TIME 0.25
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:NADC: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:NADC: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:NADC: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:NADC:PRAM:LOFF 1
SLOT ATTENUATION
Input value for the level reduction in dB 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
