SDG Function generator output amplitude is double the setpoint when I modulate the output. Is this OK?
February 16, 2022
This is expected. When the AM depth is 0%, the output amplitude is the carrier’s amplitude. When the AM depth is 100%, the amplitude of the modulated waveform will be 2x the setpoint.
Common Fuse Information
February 9, 2022
Fuses are a common circuit element and are key to protecting from overvoltage and overcurrent situations that can damage important circuits. Fuse markings are typically stamped symbols located on the metal cap of the fuse. Here is a helpful guide to common fuse markings used with instrumentation, taking a common fuse type as an example: … Continued

Do your instruments support UDP communications over LAN?
August 5, 2021
Not at this time. Many instruments support communication via sockets (port 5025) and telnet (port 5024) but the port numbers cannot be changed. If you use VISA, you can implement LAN via TCP/IP, which does not need a port number. Here is a listing of current SIGLENT instruments with Socket and Telnet Support.
SDG available waveform lengths
July 29, 2021
The SDG series of arbitrary waveform generators allow you to create any function you wish. Here are the memory depths available for building arbs for each model:
How to check available internal memory?
July 29, 2021
Simply access the Save/Recall menu for the instrument in question and select Local. The menu will show used/total amounts. Here, the SDG6X has approximately 83 MB and the SDG1X has 85 MB of memory:
How do I find the Spurious Free Dynamic Range (SFDR) for an SDG function generator?
May 21, 2021
If the SFDR is not listed directly in the specifications, you can find it by selecting the largest value between the harmonic and non-harmonic spurious data from the specification sheet at the frequency of interest. For example, here is the SDG6X generator specs for harmonic and non-harmonic distortion: If the signal of interest was … Continued
Are SIGLENT products certified by a Nationally Recognized Test Laboratories (NRTL)?
May 7, 2021
Per OSHA, a Nationally Recognized Testing Laboratory (NRTL) is an independent third-part laboratory recognized by the United States Occupational Safety and Health Administration (OSHA) to test and certify products to applicable product safety standards. Examples of NRTLs include UL, CSA, and TUV. Many SIGLENT products are TUV certified, which also covers UL and CSA requirements. To … Continued
Can I output two different arbitrary waveforms with an SDG?
April 22, 2021
Yes. Two-channel SDGs (SDG1000X, 2000X, and 6000X) can output two separate arbitrary waveforms. Load the waveforms into the instrument Select the channel you wish to load to and then press Save/Recall Select the arbitrary waveform you wish to output for that channel Repeat steps 2-3 for the other channel Enable outputs Here is an example … Continued
