Duty Cycle Range : 0.0170%~99.983% , Resolution 0.0001%(<8.5kHz)
Duty Cycle Range (Extd.) : 0.0000%~100.0000%, Resolution 0.0001%
AFG can be used for performance test of Servomotor.
The pulse duty variable resolution can be set up to 0.0001%.
PWM control signal for Servo motors
The settable duty times depend on the rise & fall time settings, as defined below:
Duty ≧ 0.625×100×[rise time - 0.6ns +fall time - 0.6ns]/period
Or Duty ≦ 100 - {62.5×[(rise time - 0.6ns) + (fall time - 0.6ns)]/period}

High resolution duty setting
Freq < 25MHz (20MHz AFG-3021/3022): 0.01ns pulse width (or 3 digit resolution)
Freq < 8.5 kHz: 0.0001% duty cycle
The Extended Mode function extends the setting range of the pulse duty cycle to 0%100%
and the setting range of the width to 0.00ns-1000ks
