My memory is a little rusty, but IIRC

With remote control (RC) servos, there is a pulse width between 1ms and 2ms 
to give minimum to maximum angle.  
There is pulse repetition rate of 20ms.

I found these 
<https://en.wikipedia.org/wiki/File:Sinais_controle_servomotor.JPG> 
<http://www.seattlerobotics.org/encoder/200009/Servos.html>

Pulse width cycle time 20ms, repetition 50Hz
Pulse width duty 5% to 10%
