Programmatically selecting a built-in arbitrary waveform with an SDG
January 3, 2019
The SDG series of arbitrary waveform generators have a number of built-in arbitrary waveforms including health-related waveforms like cardiac and math waveforms like sinc. To read the available waveforms, you can send the following string: STL? This will return a list similar to the following (the exact return data depends on the instrument model and firmware … Continued

Test and measurement equipment is exempt from FCC emissions limits per CFR 47, Part 15, para 15.103(c): https://www.gpo.gov/fdsys/pkg/CFR-2002-title47-vol1/pdf/CFR-2002-title47-vol1-sec15-103.pdf Specifically: “(c) A digital device used exclusively as industrial, commercial, or medical test equipment.”
Create an arbitrary waveform using Coordinate Mode with EasyWave software
August 24, 2018
There are a number of ways to create waveforms for arbitrary generators. The correct method depends on: The number of segments of the waveform? Required precision of the location of each sample? Complexity of the waveform? Is it a number of pulses or a number of complex curves/small details? For sequences of pulses/square waves or to … Continued
Create variable duration waveform bursts using Gated Bursting techniques with SIGLENT SDG generators
August 23, 2018
Some applications require sourcing a waveform with variable duration on and off times and/or delivering variable width bursts of a specific waveform type. This is typically the case when you want to control the amount of energy delivered to the device-under-test (DUT). Bursts of signals with dwell or dead time between bursts can limit the … Continued
Waveform Combination and adding noise to SDG1000X, SDG2000X, and SDG6000X generator output signals
May 4, 2018
The X series of SIGLENT SDG arbitrary generators, including the 1000X, 2000X, and 6000X models, offer a large array of adjustments and features that can make common tasks quite simple. One common application is to add a certain amount of noise to a standard waveform and then adjust the characteristics of the noise level. This … Continued
USB Connectivity Checklist
April 24, 2018
The Universal Serial Bus (USB) is very popular and has added a tremendous level of convenience and flexibility to computer and peripheral controls, including test and measurement instrumentation. As with all technology, it isn’t always sunshine and blue skies. Here are some common troubleshooting steps for USB connection issues: – Is the instrument plugged in … Continued
Potential Solutions to Easy software window rendering/font issues
March 8, 2018
The installation of SIGLENT EasySpectrum and other “Easy” software is typically uneventful. But, there may be an occasional issue. Here are some steps that may help clear up any issues that you may encounter: Here is an example of a mis-rendered window view of EasySpectrum: Here are some steps that may help fix the issue: … Continued
Format for programmatically building an Arbitrary Waveform for SDGs
February 26, 2018
The SDGs require UTF8 formatting for the words used to build an arbitrary waveform. The code may report “UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0x80 in position 77: ordinal not in range(128)” This indicates that the arbitrary waveform data is coded as “ascii” which is not the expected data format “utf8”. Here is the proper … Continued
Smooth output transitions with SDGX series AWGs
December 27, 2017
INTRODUCTION: Many waveform generators are based on the Direct Digital Synthesis (DDS) technique. This design has become common primarily because it features great stability and flexibility. But, not all DDS based generators have the same output performance. In some situations, the output waveform will not smoothly transition from one setting to another. This is typically … Continued
