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

This LabVIEW VI (version 2018) provides a simple platform to begin creating LabVIEW programs. You can download the VI here: VISA_IDN.ZIP In this example, the user can: Select the connected instruments from the VISA Resource List drop down menu: NOTE: USB devices will automatically appear. For LAN connections, you will need to add the device. … 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, SDS5000X, and SDS6000A series of oscilloscopes. When combined with a … Continued
