How to observe QAM singals in time-domain in Simulink?

I am trying to build up an OFMD transmitter by using Simulink. The chosen modulation scheme is 64-QAM. I am wondering how to observe the QAM signals in time-domain.

My simulink model consists of the following key blocks: Random integer generator, QAM modulator, S/P converter, IFFT block, Cyclic prefix block, buffer and Spectrum scope.

After the IFFT algorithm, the frequency-domain QAM signals in converted to time-domian signals. How to observe the QAM signals in time-domain?

Many thanks if someone can give some guidance./Lei
