Timing error regarding mixed frequencies

Dear Sir or Madam,

We tried to make an easy Optisystem simulation, where we have mixed two electrical generated frequencies with each other. The frequencies we have chosen for this example
were 14.5 GHz and 10 GHz, so we expected the result should have a period time of 2 ns. A corresponding file is attached. In the simulation we were not able to see this
2 ns periodicity and it looks for us, that there is something like a small error accumulating over time. It would be great, if we could have some support in this regard
to resolve our problem.

Kind regards,
Paulomi Mandal
