ADL5721 Eval Board Noise Figure

Hello,

I am seeing a discrepancy in my signal budget that contains the ADL5721. We have the ADL5721 eval board and are noticing around a 0.5 dB discrepancy in noise figure between what we measure ourselves and the data that is provided in the datasheet. We have tried various test configurations and still can't match the datasheet values, so any insight would be very helpful. Below is a plot of the discrepancy we are seeing. Thanks in advance.
