20 Tektronix Streamlines Compliance Testing with NI TestStand Application: A scalable compliance test solution that can support multiple standards and reduce complexity as well as test time. Challenge: Designing a framework for compliance testing that reduces complexity and testing time. Key Benefit: NI TestStand is an open flexible platform that supports multiple instruments, future standards, and a variety of buses, as well as the execution performance requirements needed to reduce compliance test time. By using NI TestStand, Tektronix reduced compliance test time by approximately 70 percent. Jit Lim, Tektronix Inc.
