PXIe-6943 - 1

50 MHz Digital Test Instrument The PXIe-6943 Digital Test Instrument (DTI) provides 32 high-performance digital I/O channels in a space-saving, single-wide PXI Express compatible module. The PXIe-6943 DTI operates at data rates up to 50 MHz with 1 ns edge placement, variable slew rates, and <3 ns channel-to-channel skew. Product Information The PXIe-6943 DTI for PXI Express provides the basis for a complete state-of-the-art digital solution at the subsystem level. The PXIe-6943 is the solution for both legacy digital replacement and new digital test stations for applications including aircraft/avionics, weapons systems, spacecraft, semiconductors and medical devices. Applications for a Digital Subsystem The PXIe-6943 DTI forms the backbone of a digital subsystem that may include switching, analog instrumentation, and even an RF subsystem. The proven PXI instrumentation platform is a time-tested approach for facilitating the integration of these different technologies at the device level by allowing the free mixing of PXIe-6943 modules with other PXI modules for added functionality. In addition, the PXIe-6943 modules can be pre-integrated at the subsystem level suited to a specific application. Astronics Test Systems offers custom design and integration services to create subsystems or fully integrated systems for functional testing on a variety of complex Devices Under Test (DUTs), including satellites, weapons systems, aircraft LRUs/ SRUs, and certain classes of semiconductor devices. From devices to turnkey systems, Astronics Test Systems can deliver all hardware and software solutions, including the Test Program Set (TPS) itself. Designed for High Reliability The PXIe-6943 DTI employs comprehensive thermal design to ensure reliability with excellent cooling, monitoring, and protection. The pin electronics devices on the PXIe-6943 employ a large heat sink, and there is also on-board temperature monitoring that protects the pin electronics from overheating and provides over-temperature shutdown. • 50 MHz digital stimulus and response with 1 ns edge placement resolution • Engineered for reliability with an advanced thermal design, temperature monitoring, and over-temperature shutdown • Innovative software tools to speed test development • Scalable design supports synchronized digital test systems from 32 to 224 channels • High-speed data sequencer provides control of stimulus/ response patterns • Optional software tools simplify legacy replacement and preserve TPS investment TEST SOLUTIONS
