An oscilloscope is a test instrument used to capture and display a graph of the waveform of an electrical signal over time. For example, it can graph voltage (y-axis) versus time (x-axis) on its display. Oscilloscopes are powerful tools for designing and testing electronic equipment. They play a very important role in determining whether system equipment components are working properly and which components are malfunctioning. They...
Using an arbitrary waveform generator, test engineers can verify the design of a circuit in just a few steps: (1) activate the output control; (2) select the waveform to be generated; (3) connect the output to the device under test; and (4) verify the performance of the device under test using an oscilloscope. The following is an example of the design of the output control circuit.
A multimeter is an instrument that can measure a wide range of parameters, such as alternating (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and so on. Modern digital multimeters use digital and logic technology to become smaller and smaller with more and more built-in functions. By introducing digital technology, digital multimeters can provide graphical displays, data logging and signal digitization as well as...
The Function Generator provides a preset list of waveforms or code patterns that it can generate. In a function generator, the user can change waveform parameters such as frequency, amplitude, and offset, as well as add simple distortion. Arbitrary waveform generators are more complex and can emulate real-world signals. Arbitrary waveform generators utilize pre-stored digital data to generate these waveforms,...
