    Power Supply Design: Load Step Response with a SIGLENT DC Electronic Load

     April 3, 2020

    In this video, I compare the response from two power supplies using a stepped load to show the differences between a well-tuned supply and one that exhibits excessive ringing. Also, add in some basic instrument requirements to help get you started making your own step load tests.

    Here, I use a SIGLENT SDL1X-E DC Electronic load to perform the dynamic load requirements, an SPD1168X power supply to power the board, a CP4070 current probe to monitor the load current, and a SIGLENT SDS2354X Plus oscilloscope to measure the response and perform some averaging to clean up noise.

    Operating Tips **************************

    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:

    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

    How do I directly control an instrument using LAN?

     February 16, 2021

    For convenience, we recommend connecting your instrument to your LAN using a router that can configure DHCP directly and use an internet switch to connect the LAN to the instruments you wish to control. In some cases, you may wish to directly connect your computer to an instrument LAN port without a LAN available. This …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 18, 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
