You should fixture the balun under test on a ground plane with 4 connectors grounded to that plane. The 4 analyzer cables go to these connectors. You don't connect anything from the DUT to the groun
Just my $0.02 Danny E73M This is a good point. If the cores are sitting close to a ground plane will the small asymmetries between the conductors in the bifilar turns and the ground plane be large en

Unfortunately that test doesn't subject the balun to the maximum CM stress it might experience in a typical application - at worst it subjects the balun to a CM voltage equal to the full differential
