In simulations the flow graph will be idle between frame transmissions and the phy will output the frames back-to-back. This is why there is a packet pad block to add some zeros between frames in case you need it. If you have an SDR connected, the SDR will stop transmitting when there is nothing to send, but the receiver will, of course, continue to sample and, therefore, output noise samples between frames. The number of samples depends on the sample rate and the time between frames. However, this is only a rough timing. The inter arrival time might vary by some milliseconds.
