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

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.

DIY Spectrum Analyzer Input Protection

May 22, 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

Secure products without K-lock slots

May 20, 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

Programming Example: Using VXI11 (LXI) and Python for LAN control without sockets

October 3, 2018

In an effort to meet the demands of remote monitoring and control, modern test instrumentation is leveraging more communications busses and than ever before. Each type of bus can also have numerous layers that can be utilized for specific advantages. The VXI bus and subsequent software drivers form a convenient software API that can make remote control … Continued
