There are terrible noise (sine wave) on the AD5560 FORCE OUTPUT while operating

Hello , mates

I have a strange terrible problem when operating my AD5560 board. Eight AD5560s are powered by a common -5V power rail ( LTM8027 )  , and each chip's HCAVDD powered by 10.5V  independently generated from LTM4622A . 

Now when I force voltage on a DUT ,  there are always serious noises added to a DC output , as the picture shown  below .

Does anyone meet the same or similar case before ?

I 'm looking for you ...

Thank you all in advance .
