Verification of a working remote communications connection using NI – MAX 20th August 2021
Automating a test can dramatically increase the productivity, throughput, and accuracy of a process. Automating a setup involves connecting a computer to the test instrumentation using a standard communications bus like USB or LAN and then utilizing code entered via a software layer (like LabVIEW, .NET, Python, etc..) to sequence the specific instrument commands and process data. This process n...

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

Power Supply Design: Load Step Response with a SIGLENT DC Electronic Load 20th August 2021
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. In this test, a DC electronic load is used to...

EasyPulse Technology and Its Benefits

EasyPulse Technology and Its Benefits 20th August 2021
INTRODUCTION: The majority of modern arbitrary/function waveform generators utilise 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 o...

Programming Example: Create a stair-step waveform using Python and PyVISA using LAN (SDG1000X, SDG2000X, SDG6000X) 20th August 2021
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 with understanding the req...

Multi Channel function generator synchronisation 20th August 2021
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 mult...

Inter Modulation Distortion (IMD) testing 20th August 2021
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 analyser. IMD is an important test for verification of audio amplifiers and radio receivers as hig...

AWG Basics

AWG Basics 20th August 2021
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 to configure and deliver a known or simulated signal can be a critical addi...

The basic output waveform and related parameters of the arbitrary waveform generator 20th August 2021
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 can no longer meet t...

Secure products without K-lock slots 20th August 2021
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 the instrument. Here is an example: https://www.kensington.com/p/products/s...
