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

SPD wiring suggestions
March 7, 2019
The SIGLENT SPD series of power supplies have only positive voltage and current setpoint values. That is, you can select voltages or currents that are from 0 to the max value (0-32 V, for voltage.. as an example for the SDP3000X/X-E). Here are the suggested wiring configurations to achieve both positive and negative potentials at the … Continued

SPD constant current performance (current compliance protection)
January 3, 2019
The SIGLENT SPD series of power supplies offer constant current mode. This setting limits the current output of the specified channel and can be used as a constant current source and to protect your device-under-test (DUT). In this tip, we show the typical performance of the SPD as it switches between constant voltage (CV) and … Continued
SPD programming tips
December 26, 2018
The SPD series of power supplies feature remote programming capabilities and can be controlled via USB or LAN connection. In this note, we will use Python and PyVISA to create a program that will connect to an SPD, enable the output, delay, and then disable the output. There are two areas that differ from some … Continued
