TPSM863252EVM: Output Ripple

Part Number: TPSM863252EVM

Tool/software:

Customer did a ripple/noise measurements on the EVM with respectively loading of 1.5A and 3A(12Vin to 5Vout), and the measurement method is using shortcut probe like diagram shown. 

As a result, Vpk-pk ripple/noise is up to 700mV. it's worse than one shown on EVM. Could you help to clarify if any missing? Very thanks.
