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 failing. They can also help you determine if newly designed components are working as expected. This can be done by analyzing signal parameters such as amplitude, period, frequency, rise time, and pulse width. Modern digital oscilloscopes can also perform mathematical operations on waveforms, such as Fourier transforms, for faster analysis.
Vector network analyzers (VNAs) are test instruments that measure electrical network parameters. They are essential for radio frequency (RF) and microwave component analysis of a wide variety of passive and active devices including filters, antennas and power amplifiers. Network analyzers are ideal for transmission, reflection and impedance measurements as well as s-parameter measurements during design and production. Network analyzers...
View Full VersionWhat does the frequency of electricity mean? Here are the basics of frequency, regionality, and measurement Since electricity and voltage are invisible things, many people will think they are elusive. But in fact, they are only invisible, and it is not difficult to understand them. Below, we will introduce the frequency basis of electricity and voltage in an easy-to-understand way, regional differences in frequency, and how...
View Full VersionA signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. The information provided in the time domain (e.g., the signal pulse on...
View Full VersionThe 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,...
