SPD constant current performance (current compliance protection)
February 15, 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 29, 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

What is the difference between a switching and linear power supply?
October 24, 2017
Linear DC regulated power supplies (“linear supplies”) alter the output voltage to the required value through the power frequency (50/60 Hz alternating current) voltage transformer. After being lowered (or raised) to the appropriate AC voltage value, the waveform is rectified, filtered, and stabilized by a voltage regulation circuit, and is then output as a regulated … Continued
How to install the USBTMC driver
October 24, 2017
SIGLENT Technologies uses a broad range of products that utilize the USBTMC unified protocol to communicate with the host computer and control. Users can use SIGLENT provided PC software to send commands to remotely control the instrument. In addition, you can use NI-MAX (National Instruments Measurement and Automation Explorer) for instrument control. Here is an … Continued
Calibration Traceability
October 23, 2017
Excerpt from the ANSI-ASQ National Accreditation Board: http://anab.org/news/newsletter/winter-2014/nist-traceability-statements NIST Traceability Statements Many calibration customers request on their accredited calibration certificates a statement that the measurement is traceable to the National Institute of Standards and Technology (NIST). They want assurance that the standards used for the calibration are ultimately traceable to the International System of Units … Continued
