    Hi,
    

    While testing the ADAR1000 EVAL1Z board in Tx mode ( for single channel gain) it is necessary to terminate the other ports that are not in use or we can leave it open.

      Hi akladha, 
      

      During test, it is best practice to terminate the unused channels into a 50 Ohm load, especially if the other channels are active. The TX path is high gain (~40 dB) so any noise or extraneous leakage signals can impact the fidelity of a single channel measurement. 
      

      Regards, 
      Sam
