PNA calibration

I am newly user of PNA N5242B and I use 85052D calibration kits to do the calibration.

However, when I finished the calibration wizard (Smart Cal), the signal just went wrong.

For example, the S21 of the thru was not a line but randomly like noise.

The screen did show from the NO COR to C 2port.

Can somebody tell me what happened ?
