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

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...

Inter Modulation Distortion (IMD) testing

Posted on: June 18th, 2021 by Doug Lovell

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...

Multi Channel function generator synchronisation

Posted on: June 18th, 2021 by Doug Lovell

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. ...

Secure products without K-lock slots

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...

AWG Basics

Posted on: June 18th, 2021 by Doug Lovell

18/06/2021
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

Posted on: June 18th, 2021 by Doug Lovell

18/06/2021
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...
