Default O2 Sensor Check

I have a 2005 SRX 3.6 and am getting the P0430 code. The check engine light stays on. The car runs great until it gets really warmed up, then it starts chugging some.
I know it has to do with the catalytic converter. Before I get too involved with that, I would like to check the O2 sensors. Can someone tell me how to check to see if they are bad?

Thank you.
