How to measure the IDD2 of ADUM1200 by test equipment?

Hello,

    As I measure the parameter IDD2 of ADUM1200，the lumped capacitance in J750 test equipment is 66pF (TYP). You know, in the datasheet, if the outputs load a capacitance(15pF in the datasheet),the IDD2 value will be higher than no load. While the datasheet shows the IDD2 value under no load. The lumped capacitance in the test equipment is unavoidable. So,how to measure IDD2 by test equipment?
