Arbitrary waveform generators are a type of signal generator that generate realistic waveforms and provide a wide range of excitation signals. The various types of signals they generate are often used to stress test devices for communication protocols.
A DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or a switching method. Switching power supplies are more efficient, lighter in weight and smaller in form factor. Linear power supplies can achieve lower noise, but this is no longer an advantage with modern switching power supplies. ,
View Full VersionAlternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power loss by increasing or decreasing the voltage of the AC line. Alternating current (AC) is a form of household electricity -...
View Full VersionSpectrum 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 VersionA function generator is an electronic test device that generates a variety of standard waveforms for a device under test (DUT), such as sine, square, ramp, or sawtooth waveforms. In circuit design and circuit boards, testing often requires the use of controlled signals to simulate routine operations. Testing physical systems and sensors often requires stable and reliable signals that are as low as a few microvolts and may be as high as...
