Phase output of an AD5933 evaluation kit

I was testing using an EVAL-CN0217-EB1Z evaluation kit. No matter testing an individual resistor (10K, 100K), capacitor(15pF to 1000pF), or  parallel or serial combinations, the results always shows correct |Z|, but suprisingly zero phase. Is there anything wrong with my setting?

I tried put DUT at either R6 or Z position(with matching resistor on RFB).
