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.
