+The noise is only calculated once on the host, and simply added to the waveform buffer. This means that for cyclic waveforms the noise will be the same on each period.

-  - Select Math mode and input a function sucha s 2*(cos(6*t)*sin(2*t))
+  - Select Math mode and input a function such as  2*(cos(6000*pi*t)*sin(2000*pi*t))
+  - Set sample rate to 75MSPS (this is the sample rate of the generated signal)
+  - Set record run length to 1ms.
+  - Run the signal
   - Monitor oscilloscope
+<note>Sample rate & record length parameters: Since t goes from 0 to infinity, we need to specify how long will t be generated for the specified function - in this case it will go from 0 to 1ms with 75 MSPS granularity(13.3333 ns). These settings will generate (1 * 10^-3) * (75 * 10 ^9) points = 75000 points.
