How to Extract Data from the Binary File of Siglent Oscilloscope
June 12, 2024
Data can be formatted in many different ways. Binary data formatting often provides the smallest payload size and therefore transfers via USB/LAN more quickly. Unfortunately, binary is very difficult to interpret by humans. So, binary data is often reformatted to other types (ASCII, etc..)/ Here is a link to the binary data format for many … Continued

Baltic Labs: Generate a stereo-FM multiplex waveform with Python and AWG
October 20, 2022
Sebastian @ Baltic Labs had a recent project that required a stereo-FM multiplex (MPX) signal containing two different tones in the left and right stereo audio channels. This article shows how to generate such an MPX signal for Siglent SDG-series arbitrary waveform generators with Python and PyVISA. Generate a stereo-FM multiplex waveform with Python and … Continued
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
Comparison/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
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
Programming Example: SDS Oscilloscope save a copy of a screen image via Python/PyVISA
February 26, 2020
Here is a brief code example written in Python 3.4 that uses PyVISA to pull a display image (screenshot) from a SIGLENT SDS oscilloscope via USB and save it to a drive on the controlling computer. NOTE: This program saves the picture/display image file to the E: drive, which may or may not exist on … 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
