Application Examples

AFG3000 Series Quick Start User Manual

Pulse-width modulation is used for controlling the speed of a DC motor or the luminance of an LED (Light Emitting Diode). 
Use the arbitrary/function generator PWM function to control the DC motor speed.

1. Connect the arbitrary/function genera-

tor output and a DUT using a 
BNC-to-alligator clip adapter.

2. Select Pulse as an output waveform 

and then select PWM as a modulation 
type.

Set the frequency to approximately 
100 kHz.

3. Connect the output to an oscilloscope. 

Confirm that a pulse-width modulation 
waveform is displayed on the oscillo-
scope screen.

Select Pulse Duty and change the duty 
rate. Observe that the motor speed 
changes if you change the duty rate.
