In the # Frames field, you can choose if the background traffic
generation is continuous or if a limited number of frames is
to be sent.
On the Frame tab, you can choose the MAC source address for
the simulated traffic to be the FrameScope Pro itself, or 10,
100, or 200 stations. If you choose to simulate multiple
stations, the amount of traffic generated — specified by
number of calls — will be distributed among the number of
stations selected.
