Sense]:Acp:offset:list:rattenuation:auto Off|On|0|1 - Agilent Technologies E4406A VSA Series Programmer's Manual

Remarks: Remember that the attenuation that you specify is
always relative to the amount of attenuation used for
the carrier channel. Selecting negative attenuation
means that you want less attenuation used. For
example, if the measurement must use 20 dB of
attenuation for the carrier measurement and you want
to use 12 dB less attenuation for the first offset, you
would send the value −12 dB.
You must be in Basic or cdmaOne mode to use this
command. Use INSTrument:SELect to set the mode.
