An AC power supply is responsible for providing AC power to the load. The power input can be either AC or DC. You need an AC power supply because the power from the wall outlet does not meet the specifications of the load. In order for the load to operate properly, you need to transform the AC power supply to tune the AC power from the supply to the voltage, current, and frequency required by the device. This can be accomplished by raising or lowering the voltage and then filtering the signal.
You can use an AC power supply for testing. The AC power supply can emulate grid outages, harmonics, surges, or other events that may cause the device under test (DUT) to fail.
Spectrum analyzers measure the amplitude of an input signal versus frequency over the entire frequency range to determine the power of the signal. Spectrum analyzers are capable of performing tests such as noise figure and signal-to-noise ratio (SNR) to characterize the performance of a device and its contribution to overall system performance. For more information, see the application guide Spectrum Analysis Basics. ,
View Full VersionUsing 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.
View Full VersionAll modern oscilloscopes are digital storage oscilloscopes (DSOs) that use digital signal processing to capture and display analog signals. If the oscilloscope has the ability to observe these signals simultaneously in the digital domain, it is a mixed-signal oscilloscope (MSO). If the oscilloscope has a built-in spectrum analyzer function, it is a mixed-domain oscilloscope (MDO), although this term is less common. ,,...
View Full VersionIn-phase quadrature modulation (IQ modulation) is the main modulation scheme used in communication applications. It is popular because of its efficient use of bandwidth, meeting the increasingly urgent need for bandwidth in a world where data volumes are growing exponentially. It is important to test with simulated IQ signals because designers are always faced with a lack of bandwidth in an interference-ridden spectrum. Example...
