Starting in 2017, SIGLENT has been using this format for serial numbers for instrumentation:

Common Fuse Information

February 24, 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

Protecting an SPD from an active load/battery

December 28, 2021

The output channels of SIGLENT SPD series power supplies have a protection diode with protection voltage and current rating of < 32V/1A. If the reverse voltage and current of the battery or power source connected to the SPD is > 32V/1A, you should add a protection diode between the power supply and load as below:

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.

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:

SPD output performance

February 5, 2021

The constant voltage-constant current transition with SPD power supplies is controlled by a diode and has a typical response time of approximately 1 ms. The capacitance of SPD3 and SPD1 models is about 920uf.
