We usually use time as a frame of reference, focusing on when certain specific events will occur. This includes electrical events. Oscilloscopes allow you to view the instantaneous value of a particular electrical event (or the voltage value of some other event converted by an appropriate transducer) over time. In other words, we can use an oscilloscope to view the waveform of a signal in the time domain. Fourier theory tells us that any electrical phenomenon in the time domain consists of one or more sinusoids with the appropriate frequency, amplitude, and phase. This means that we can convert a time-domain signal to its frequency-domain equivalent. Spectrum analyzers and signal analyzers can measure the energy at each specific frequency in the frequency domain.
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 done by boosting...
View Full VersionTest engineers and developers use oscilloscopes to display, visualize graphs, and analyze electrical signals during research and development, verification, quality assurance, and troubleshooting or debugging of electronic systems, boards, and integrated circuits. Oscilloscopes play a key role in a variety of applications and technologies across all industries, including high-speed digital electronics, optical communications, RF, power electronics, automotive and aerospace...
View Full VersionNetwork analyzers perform component characterization tests. A network analyzer provides a calibrated excitation signal to an RF network or device under test (DUT) and measures the vector response at frequency with phase and amplitude information. A VNA provides transmission (transmission coefficient, insertion loss, gain), reflection (reflection coefficient, VSWR, return loss), and impedance measurements, as well as s...
