EKIT01-HMC7282B perfomance


I received an inquiry about a performance of EKIT01-HMC7282B from out customer. The customer got new EKIT01-HMC7282B in recent days. But the output signal on the eva kit is not good as another kit. The customer got the kit before. Do you have any comments about the output save form (please refer following picture)? How should we do for improving the wave form?
