It is possible to reduce errors generated between multiple D/A conversion paths. A characteristic acquisition device includes [1] an arbitrary signal generator that converts a first (second) input digital pattern into a first (second) output analog pattern, [2] a digitizer that converts a first input analog pattern into a first output digital pattern, and [3] a characteristic acquisition device that includes a first transmission characteristic deriving unit that derives a first transmission characteristic which converts the first input digital pattern into the output digital pattern where the input analog pattern is the first output analog pattern, a second transmission characteristic deriving unit that derives a second transmission characteristic which converts the second input digital pattern into the output digital pattern where the input analog pattern is the second output analog pattern, and a transmission characteristic ratio deriving unit that derives a transmission characteristic ratio which is a ratio relating to the first transmission characteristic and the second transmission characteristic.
