![]() ![]() The two arrows right below the numeric keypad can change which digit is to be adjusted. Both frequency and amplitude adjustment buttons are in the same section below ‘Run Mode’ section, which can be set either by the numeric keypad or by the knob above that keypad. Sine, square and triangle waveforms (3 most used waveforms in this lab) can be selected from Function section. It is able to provide 12 different standard waveforms, with dual-channel capability. The function generator we are going to use for this lab is a Tektronix AFG 3022B, as shown in Figure 2 – 1. It is widely used in development, testing and repair of electronic equipment, for example, as a signal source to test amplifiers, or to introduce an error signal into a control loop. They can be converted from one form to another using the following equations:Ī function generator is a piece of equipment used to generate electrical waveforms. Special attention must be paid when measuring the voltage or current of an AC circuit, as three different forms of voltage or current may be obtained from a measurement, namely V magnitude or I magnitude, V RMS or I RMS or V peak-to-peak or I peak-to-peak. Other time-varying applications, depending on the application, include the square wave and the triangular wave.Ī sinusoidal AC voltage or current is described by its amplitude, frequency and phase, for example,, where A is the magnitude, the angular frequency and is the phase. In AC circuits, the voltage and current sources are time-varying, with the most common being a sinusoidal variation. To use a digital multimeter to measure AC voltage and current.Īn AC (alternating current) is a function of time.To use an oscilloscope to measure frequency, period, voltage (magnitude, peak-to-peak, maximum, minimum, and etc), DC offset, etc, of the waveform. ![]() To use an oscilloscope to display and record a waveform.To understand the basics of AC (alternating current) circuits. ![]()
