SDS1000X-U Series

Jitter spectrum measurements with a digital oscilloscope

February 21, 2022

Clockworks Signal Processing released an application note that measures jitter using a SIGLENT XE series of oscilloscopes. The basic idea is simple enough – measure the clock edges and see if they are all exactly evenly spaced or if they change (jitter) over time. A non-uniform clock fed to an ADC or DAC will produce … Continued

Differences in SDS1000X-U and SDS1000X-E oscilloscope models

December 8, 2021

The four-channel SIGLENT SDS1000X-E models (SDS1104X-E and SDS1204X-E models) and SDS1000X-U oscilloscopes are based on very similar digital platforms and share many features. They do have some differences that could be important for you to understand prior to selecting the proper product for your application. Here are the major differences (Note XE is used to … Continued

SDS FFT performance on low frequency signals

February 26, 2019

Like many modern oscilloscopes, the SIGLENT SDS series feature FFT math functions that calculate frequency information from the acquired voltage vs. time data. FFT stands for Fast Fourier Transform, and is a common method for determining the frequency content of a time-varying signal. Converting time domain data to the frequency domain makes measuring characteristics like … Continued
