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

Programming Example: Create a stair-step waveform using Python and PyVISA using LAN (SDG1000X, SDG2000X, SDG6000X)

April 24, 2020

The SIGLENT SDG series of arbitrary waveform generators can use waveforms created programmatically. The waveform data can be sent as individual samples formatted as binary little-endian, 2s complement values. In this programming example, we create a 10 point arbitrary waveform that starts at the least-significant bit and steps up to the most-significant bit to help … 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 17, 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

Multi generator synchronization

July 19, 2019

1. Introduction Multi-channel function generators are useful in many situations. For example, in Radar 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. … Continued

Secure products without K-lock slots

May 27, 2019

Many products have Kensington, or K-lock slots to help provide a location to secure a cable lock or other device to help prevent theft. Some products do not have locations for cable lock connections. In this case, we recommend using a special glue or physical attachment system to secure the cable to the case of … Continued

DIY Spectrum Analyzer Input Protection

May 24, 2019

Spectrum analyzers like the SIGLENT SSA3000X and SVA1000X series are extremely useful instruments that can provide invaluable insight into broadcast signal performance, transmitter troubleshooting, and interference as well as RF device characterization and EMC testing. But, like other spectrum analyzers, they are very sensitive and can be damaged easily, if the proper precautions are not … 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. Now, using a Siglent oscilloscope, like the SDS1204X-E with the newly released Bode Plot Ⅱ software, together with a Siglent arbitrary waveform generator (SDG or … Continued
