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
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:
RoHS compliance
December 28, 2021
Many SIGLENT products are RoHS compliant to EU 2015/863. This is also known as RoHS 3 Check the datasheet for the product in question to find more information.
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:
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
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.

Common SPD power supply issues
September 14, 2020
The most common SPD issues are typically solved by switching the input switches (on the rear panel) to the proper voltage values. As the first step to troubleshooting, please ensure that the power switches located on the rear panel are correctly set for the line voltage of the area the instrument is being used in. … Continued
SPD Local Front Panel Lock Out SCPI commands
November 21, 2019
The current version of the SPD programming commands (located in the Quick Start Guide) do not include any front panel lock commands. These are typically used to control the functionality of the front panel keys. Locking the front panel prevents accidental changes to instrument operation during remote control. The SPD1000X and SPD3303X/X-E have three commands … Continued
