SDG1X firmware 1.01.01.33R1 adds TrueArb capability
May 27, 2019
Starting at firmware version 1.01.01.33R1, the SIGLENT SDG1000X series of arbitrary waveform generators now feature TrueArb output capability. Traditional arbitrary waveform generators use DDS (direct digital synthesis) to create waveforms. This technique is very powerful, but at higher output frequencies, DDS begins to lose resolution because it will skip or drop output samples in order … Continued
USB Connectivity Checklist
February 28, 2019
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
SIGLENT SPA1010 Amplifier output control
February 15, 2019
The SIGLENT SPA1010 Amplifier can be a useful accessory for applications requiring higher voltage and/or current from a signal source like a SIGLENT SDG arbitrary waveform generator. The SPA features a power-on indicator LED, Short LED, a X10 indicator LED, and a set of switches on the front panel. To use: Connect the output of … Continued

Programmatically selecting a built-in arbitrary waveform with an SDG
February 15, 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

Are your instruments FCC compliant?
December 18, 2018
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.”
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
What instruments accept SCPI commands for remote control?

All SIGLENT instruments (except for the SHS1000 and SHS800 hand-held oscilloscopes) support SCPI remote control commands. For more information, download the specific instrument programming guide located on the product page.
Generating Complex Waveforms Using Siglent’s Combine Function on the X-Series Dual-Channel Generators
October 24, 2017
It is common in engineering to combine two signals into one, such as superimposing noise on a sinusoid to simulate a desired signal containing undesired noise, or testing the OIP3 (Output 3rd Order Intercept Point) of an amplifier by generating a two-tone signal. The Siglent X series dual-channel waveform generators (SDG1000X, SDG2000X) can accomplish this … Continued
