Adjacent Channel Power—Relative Attenuation
[:SENSe]:ACP:OFFSet:LIST:RATTenuation
<rel_powr>,<rel_powr>,<rel_powr>,<rel_powr>,<rel_powr>
[:SENSe]:ACP:OFFSet:LIST:RATTenuation?
Sets a relative amount of attenuation for the measurements made at
your offsets. The amount of attenuation is always specified relative to
the attenuation that is required to measure the carrier channel. Since
the offset channel power is lower than the carrier channel power, less
attenuation is required to measure the offset channel and you get wider
dynamic range for the measurement.
You can turn off (not use) specific offsets with the
SENS:ACP:OFFSet:LIST:STATe command.
Factory Preset
and *RST:
Range:
−40 to 0 dB, but this relative attenuation cannot exceed
the absolute attenuation range of 0 to 40 dB.
Default Unit: dB
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.
Adjacent Channel Power—Relative Attenuation Control
[:SENSe]:ACP:OFFSet:LIST:RATTenuation:AUTO OFF|ON|0|1
[:SENSe]:ACP:OFFSet:LIST:RATTenuation:AUTO?
Automatically sets a relative attenuation to make measurements with
the optimum dynamic range at the current carrier channel power.
You can turn off (not use) specific offsets with the
SENS:ACP:OFFSet:LIST:STATe command.
