E8364B PNA Network Analyzer Ecal problem

Hi, 
I am trying to use the Ecal method for calibration in E8364B PNA Network Analyzer, just using 2 ports PNA1 and PNA2 at the moment.I am connecting the PNA1 to PORTA of the Ecal and PNA2 to PORTB. Even though all the connections are made properly, the error  " +187, Unable to orient Ecal module. Please ensure the module is connected to the necessary measurement ports"  keeps showing up.
On the contrary, whenever I connect the ports PNA1 and TSA1 and calibrate, its getting calibrated. Can any one help me on this matter ?

Thanks in advance.
