Power Supply Design: Load Step Response with a SIGLENT DC Electronic Load
April 3, 2020
Building a power supply that can handle various loads without oscillating can be a challenge. Computational models and computer simulations can help get your design headed in the right direction, but physical testing is essential to proving the performance of your design. One method of quickly determining stability is to use a load step response. … Continued
Testing Intrinsic Safety Barrier fusing and circuitry using an electronic load
December 16, 2019
From Wikipedia: Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. The idea is to minimize the risk of fire or explosion by physically eliminating any potential source of ignition. Many IS circuits utilize special fusing and elements that are designed to … Continued
Secure products without K-lock slots
May 27, 2019
Many products have Kensington, or K-lock slots to help provide a location to secure a cable lock or other device to help prevent theft. Some products do not have locations for cable lock connections. In this case, we recommend using a special glue or physical attachment system to secure the cable to the case of … Continued
Verification of a working remote communications connection using NI – MAX
November 19, 2018
Automating a test can dramatically increase the productivity, throughput, and accuracy of a process. Automating a setup involves connecting a computer to the test instrumentation using a standard communications bus like USB or LAN and then utilizing code entered via a software layer (like LabVIEW, .NET, Python, etc..) to sequence the specific instrument commands and … Continued
