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

Datalogging with the four-channel SDS1000X-E oscilloscope models

August 30, 2021

Datalogging Numerous test and measurement applications require data acquisition over a long time duration. Instead of milliseconds of measurement time, you may need tens of minutes or even hours of data. Normally, a data acquisition system is used for this type of application. But this may require developing software and troubleshooting code. SIGLENT has added … Continued

Oscilloscope Remote control TEK emulation mode

July 27, 2021

Overview This application note describes the features and usage of the Tektronix compatibility mode for remote control of the SIGLENT SDS5000X and SDS6000A oscilloscope series. In many cases, a SIGLENT SDS5000X/6000A scope can replace a similar Tektronix product without many changes to the existing code. Furthermore, it describes in detail the limitations of the individual … Continued

EasyPulse Technology and Its Benefits

July 13, 2020

INTRODUCTION: The majority of modern arbitrary/function waveform generators utilize DDS technology (Direct Digital Synthesis), but there are a few obvious defects using this technology directly. To solve these disadvantages, SIGLENT invented a pulse generating algorithm called EasyPulse technology. In this note, we will describe the basics of DDS and how EasyPulse can help get the … Continued

Power Supply Design: Load Step Response with a SIGLENT DC Electronic Load

April 3, 2020

Building a power supply that can handle various loads without oscillating can be a challenge. Computational models and computer simulations can help get your design headed in the right direction, but physical testing is essential to proving the performance of your design. One method of quickly determining stability is to use a load step response. … Continued

Analyzing GSM Radio Protocol with a Siglent SDS2000X Plus Oscilloscope

March 10, 2020

Two SIGLENT users, Karel and Simon Sotek, email2@avanaconsulting.de recently took a SIGLENT SDS2354X Plus oscilloscope and investigated a GSM cell phone signal. Here is their report: We took a retired Siemens A36 cellphone to learn the capabilities of this new Siglent scope. Available documentation and medium-density PCB of the selected A36 made the signal probing … Continued

Measuring the Modulation Index of an AM Signal using an FFT

June 13, 2019

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 by measuring the sideband amplitude and the carrier amplitude. In this application note, we are going to show a convenient method of using … Continued

Measuring Power Supply Control Loop Response with Bode Plot II

May 24, 2019

Introduction Stability is one of the most important characteristics in power supply design. Traditionally, stability measurements require expensive frequency response analyzers (FRA) which are not always available in a laboratory. SIGLENT has released Bode Plot Ⅱ features to the SIGLENT SDS1104X-E, SDS1204X-E, SDS2000X-E, SDS2000X Plus, and SDS5000X series of oscilloscopes. When combined with a Siglent … Continued
