I wanted to generate a very high frequency(65MHz) signal as shown. When any part of the signal is zoomed out, it should have sufficient sinusoidal components as I drawn downwards.

OK, have fun. Thanks for the announcement. Now we know what you are going to do, or wanted to do.
If you actually have any questions, then attach your data and code to read it in with the paperclip icon after you read this:

Here's my code. But when I zoom it, It just a plane line. But I need multiple sinusoids inside. How do I do that? You can do any chage to get the requirement.
Fs = 10^7;
dt = 1/Fs;
one_signal_period = 0.01;
t=(0:dt:one_signal_period-dt);
a= 5*exp(-t/0.0007);
a(1) = 0;
b=exp(-t/0.0007);
b=flip(b);
c = a+b;
plot(t,c);

Hi Reji,
Depends on how much you want to zoom out. Two things which come on the top of my head are using the zoom out function in the tools section of the plot window and the second would be setting the xlimits to a large value.
Hope it helps
