pna-x external spectrum analyzer loss

I am attaching an external spectrum analyzer to the back of the PNA-X through the J1 port. I am able to get a measurement through port 2 with the external spectrum analyzer. However, I am getting about a 30dB loss in the signal when passing through the pna-x internals vs connecting it directly to the DUT. I was wondering if there was any way to minimize this loss, or is this typical? I am currently setting the 'Port 2 Bypass Switch' from 'thru' to 'rear'.
