Application Examples Application Examples This section contains a series of application examples. These simplified examples highlight the features of the arbitrary/function generator and give you ideas for using it to solve your own test problems. Lissajous Patterns Use the AFG3000 series dual-channel model to create a Lissajous pattern and observe the waveforms with an oscilloscope. 1.
Application Examples Measurement of Filter Characteristics Use the arbitrary/function generator sweep function to observe the frequency characteristics of the 50 Ω filter. 1. Connect the CH1 output of the arbitrary/function generator and an oscilloscope CH1 input with a BNC cable. Oscilloscope AFG3000 series 2. Connect the Trigger Output of the arbitrary/function generator and the external trigger input connector of an oscilloscope. Set the oscilloscope input impedance to 50 Ω.. 1 Filter 2 3.
Application Examples Motor Speed Control by Pulse-Width Modulation 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 generator output and a DUT using a BNC-to-alligator clip adapter. DUT (example: Motor) AFG3000 Series 1 2. Select Pulse as an output waveform and then select PWM as a modulation type.
Application Examples Carrier Null (Frequency Modulation) Use the arbitrary/function generator and spectrum analyzer to observe a carrier waveform of frequency modulation. 1. Select Sine as an output waveform and then select FM as the modulation type. 1 2. Set the waveform parameters as follows: ■ Carrier frequency: 1 MHz ■ Modulation frequency: 2 kHz 3. Change Deviation. Set the deviation to 4.8096 kHz. It makes the carrier waveform null.
