a. The specification is ±0.14 dB. Note that this small relative uncertainty does not apply in esti-
mating absolute amplitude accuracy. It is included within the absolute amplitude accuracy for
measurements done with the electronic attenuator. (Measurements made without the elec-
tronic attenuator are treated differently; the absolute amplitude accuracy specification for
these measurements does not include attenuator switching uncertainty.)
