Linearity can be expressed by the amplitude of fundamental freq. component (freq. you want) relative to adjacent second harmonic freq. component.
Linearity is the best if your oscillator has only single fundamental component..
You can make a simple sinusoidal oscillator using a **555** oscillator and simple LPF..
Depending on frequency.. This

How often do you want your 5 cycles? Do you want the cycles to be switched on at a certain part of the **wave**form. It looks like pin 3 controls the output level, so link it to V cc with a high value resistor.

You can use a comparator and connect a variable DC voltage to one of the inputs to vary the trigger point on the **sine** **wave**.
Use the comparator output to trigger a one-shot such as with a **555** or a CD4098 to get a fixed pulse-width output.
