Timing and synchronization hardware aligns measurements across multiple devices and systems so data is captured at the same time or with known phase relationships. Engineers use it to coordinate distributed test systems, correlate signals from different instruments with multiple chassis, and to make phase-sensitive measurements in automated test and validation applications.

Precise timing and synchronization are essential for almost every test and measurement application involving more than one channel at a time. Although different applications, such as hardware-in-the-loop (HIL) testing, mechanical test, and radar testing, may require different degrees of precision, they all rely on known phase relationships between channels to achieve reliable and repeatable results.

When selecting timing and synchronization hardware, engineers should consider frequency accuracy, jitter and noise performance, synchronization protocol support (such as IEEE 1588/802.1AS, GPS, IRIG-B), clock and trigger import/export needs, distance between the participating devices, and slot compatibility. System scalability and software integration can also play a major role in reducing development effort. 

NI timing and synchronization hardware delivers precise clock distribution and triggering, automated and flexible routing and configuration, industry-standard timing protocol support (such as GPS, IEEE 1588, IEEE 802.1as, and IRIG-B), high level software integration with NI-DAQmx, NI-TClk, LabVIEW, and NI VeriStand, and scalable synchronization across the widest portfolio of instruments and chassis in the industry.
