RFmx
Sets the step size for the RF attenuation level. This value is expressed in dB. The actual RF attenuation is coerced up to the next highest multiple of the specified step size. If the mechanical attenuators are not available to implement the coerced RF attenuation, the solid state attenuators are used.
