Multi generator synchronization

August 7, 2023

1. Introduction Multi-channel function generators are useful in many situations. For example, in some testing the generator needs to output several phase-coherent signals and for the phase to be independently adjustable for each signal. In 3-phase power line harmonic distortion testing, a 4 channel generator is required to simulate the multiple voltages and currents. 1.1 … 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

The basic output waveform and related parameters of the arbitrary waveform generator

April 23, 2020

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 actual use, it is often necessary to artificially create some “irregular” waveforms or add some specific distortion to a waveform. Traditional function generators … Continued

AWG Basics-1

April 23, 2020

Many electronic designs feature the ability to monitor or measure input signals and then perform another task or function based on that input signal. A simple example could be a circuit that looks for an input voltage to exceed a specific amount and triggers another action after it occurs. In such cases, having the ability … Continued

Inter Modulation Distortion (IMD) testing

February 14, 2020

Two SIGLENT SDG owners and Amateur Radio operators and frequent experimenters, Steve Ratzlaff AA7U and Everett Sharp N4CY, got together and built a very thorough test procedure for testing Intermodulation Distortion (IMD) on a Loop Amplifier using a SIGLENT SDG2042X generator and SSA3021X spectrum analyzer. IMD is an important test for verification of audio amplifiers … Continued

Programming Example: Identification String (*IDN?) return with LabVIEW 2018

December 16, 2019

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 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
