PCI-8512, 2-Port, High‑Speed/FD CAN Interface Device
780683-02
The PCI‑8512 is a high-speed controller area network (CAN) flexible data-rate (FD) interface for developing applications with the NI‑XNET driver. The PCI‑8512 excels in applications requiring real‑time, high‑speed manipulation of hundreds of CAN frames and signals such as hardware‑in‑the‑loop simulation, rapid control prototyping, bus monitoring, automation control, and more. The NI‑XNET device-driven DMA engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts, minimizing message latency and freeing host processor time for processing complex models and applications.

64-Channel 250kSa/s USB Modular Multifunction Data Acquisition
U2355A
The U2355A offers multifunction capabilities in a module. It can be used like a digital multimeter in polling mode. It can be transformed to be a simple scope using the continuous mode with simple triggering capabilities. No matter if it is used as a standalone module or when plugged into a U2781A USB modular instrument chassis, the synchronization and triggering capabilities allow great flexibility in making the desired measurements. With the analog output being able to send out predefined or arbitrary waveforms make this a good tool when closed loop feedback or stimulus is required. The digital IO channels allows for closed loop control through connections to switches, relays and solenoids. The burst mode enables the U2351A to simulate simultaneous analog input acquisition.

Agile Software Testing Service
Have you felt that just testing your software is not enough? Do you believe that every stakeholder should have a say in software is tested and delivered? Agile testing follows the principles of agile software development. Agile Testing will not be carried out in silos but as a continuous process that involves all cross functional teams in a real-time feedback loop, increasing go-to-market times and speeds up release cycles. Agile processes can be inserted into any testing process.- Agile testing is not a framework but rather a set of principles or a philosophy.- Agile introduces greater collaboration, flexibility, discipline and accountability- Agile focuses on individuals, teams, collaboration and change rather than on processes, tools, and documentation.Instead of one monolithic exercise, Agile is an ongoing process throughout the lifecycle.

Composite 1×24 Video Distribution Amplifier
VDA124RM
Video Distribution Amplifiers (sometimes called a video splitter – not to be confused with a video split screen controller such as our PXD510E split screen controller) are typically used for connecting a camera or other video source to several monitors that do not have “looping” inputs. In this situation, each monitor has a permanent 75 ohm termination. With two non-looping monitors connected together, the line would be double loaded and result in a dim picture on each monitor. Using a Video Distribution Amplifier will solve this problem by driving each monitor individually at 100%.
