Developing Real-Time Test Applications with NI VeriStand: Tips and Tricks
At DMC, we’ve built dozens of real-time test systems using NI VeriStand—from battery test systems and BMS HILs to fuel cell simulators. While VeriStand offers a robust framework for deploying real-time applications, the real magic lies in the non-obvious tips and tricks our engineers have discovered through hands-on experience. Here are some of our favorite…

Real-Time Battery Testing: A Synergy of NI LabVIEW, TestStand, and VeriStand
Design and Architecture Based on the client’s requirements, DMC decided to leverage the NI software and hardware platforms for this project. NI TestStand was used as the test executive to provide configurable sequencing in the application. TestStand was wrapped in a LabVIEW operator interface and programmed using DMC’s Flex Framework and object-oriented best practices. LabVIEW…

Custom Deterministic Sequencing for a Hardware in the Loop Validation Test
Summary Hardware-in-the-loop (HIL) and production validation tests often rely on precise, deterministic sequencing to ensure that every stimulus, measurement, and control action occurs with exact timing. NI VeriStand’s real-time sequences (.nivsseq files) are widely used for this purpose, offering microsecond-level deterministic control on PXI and CompactRIO targets. While the Real-Time Sequence Editor provides a powerful…

Communications Monitoring and Emulation with MIL-STD-1553B and RS-422
Summary Communications emulation and monitoring is a core part of all avionics test projects in aerospace, but frequently involves painful editing, difficult troubleshoot, and complex requirements that aren’t easily met by a fully automated solution. As part of the SLS NASA BOLE project, DMC designed and developed a solution for HIL testing MIL-STD-1553B and RS-422…

Why Buy New? The Case for Modernizing Test Rigs in Aerospace & Defense
In the Aerospace and Defense sectors, the push to modernize aging test infrastructure is stronger than ever. With increased funding, hyper-focus on operational readiness, and shortening timelines, organizations face a critical decision: invest in brand new test rigs, or modernize the control systems and software of their existing assets? At DMC, we believe that control-system…
