This enables the function generator to handle the dramatic variation in frequency scale required for signals. You can sweep up or down in frequency using linear or log sweeps. On certain function generators the frequency control combines several different controls: one set of controls sets the frequency range, or order of magnitude, while the other selects the exact frequency. The DS345 Function Generator can frequency sweep any of its function outputs (except noise). The function generator’s frequency control is used to manipulate the output signal’s rate of oscillation. The function generator’s duty cycle is its ratio of high to low voltage time as it concerns square wave signals. If your function generator supports arbitrary. Its direct current (DC) offset control changes the signal’s average voltage with regard to the ground. You can control and configure function generators directly from MATLAB using Instrument Control Toolbox. The function generator’s amplitude control changes the voltage difference between the output signal’s high and low voltage. Some arbitrary waveform generators can also operate like an ordinary function generators and often include waveforms like square, sine, ramp, triangle, noise, and pulse as well as waveforms such as exponential rise and fall time, sinx/x, and cardiac. The majority of function generators enable you to pick the shape of the output from several options including square wave, in which the signal immediately goes from high to low voltage sine wave, in which the signal curves from high to low voltage like a sinusoid and triangle wave, in which the signal goes from high to low voltage at a fixed rate.Īdvanced function generators - known as arbitrary waveform generators - use direct digital synthesis techniques to generate any waveform that can be described by a table of amplitudes. You connect the function generator’s electrical leads to the ground and the signal input terminals to the device under test (DUT). Attach the output of your circuit to a meter or oscilloscope to visualize the resulting change in signal.Ī function generator, which is used for testing the response of circuits to commonplace input signals, produces various voltage patterns at different frequencies and amplitudes.
