The basic output waveform and related parameters of the arbitrary waveform generator
Traditional function generators can output standard waveforms such as sine waves, square waves, and triangle waves. However, in actual test scenarios, in order to simulate the complex conditions of the product in…

EasyPulse Technology and Its Benefits
INTRODUCTION: The majority of modern arbitrary/function waveform generators utilise DDS technology (Direct Digital Synthesis), but there are a few obvious defects using this technology directly. To solve these disadvantages, SIGLENT invented a…

Comparison / Differences between the SDS1000X and SDS1000X-E oscilloscope families
The original SDS1000X versus SDS1000X-E comparison has reached the end of its useful life as a buying guide. A current entry-level decision is better framed around measurement quality, channel count, memory, protocol…

Measuring Power Supply Control Loop Response with Bode Plot II
Introduction Stability is one of the most important characteristics in power supply design. Traditionally, stability measurements require expensive frequency response analysers (FRA) which are not always available in a laboratory. SIGLENT has…

Measuring the Modulation Index of an AM Signal using an FFT
Introduction In AM schemes, the modulation index refers to the amplitude ratio of the modulating signal to the carrier signal. With the help of Fast-Fourier-Transforms (FFT), the modulation index can be obtained…
