Description
The PXI-6683 module, with part numbers 782109-01 and 782110-01, falls under the Timing and Synchronization category. It is designed for precise timekeeping and synchronization across PXI and PXI Express frameworks. The module is capable of synchronization using GPS, IEEE 1588, and IRIG B signals, ensuring a broad range of applications can benefit from its features.
The NI PXI-6683H GPS,IRIG-B, IEEE 1588 Sync and Time Module is equipped with a Temperature-compensated crystal oscillator (TCXO). This onboard oscillator is critical for maintaining accurate time, irrespective of temperature fluctuations, ensuring reliable performance in various environmental conditions.
For network connectivity, the module provides an Ethernet port that can auto-negotiate 10 Mbps, 100 Mbps, or 1000 Mbps speeds. It supports Auto-MDI, meaning crossover cables are not required, and it operates in full duplex, allowing for simultaneous transmission and reception of data packets.
Regarding its integration into PXI systems, the PXI-6683 can support up to 13 PXI Star Triggers per chassis. This feature enables extensive synchronization capabilities across multiple modules within a chassis. Additionally, it boasts Propagation Delay Matching within 1 ns and a Trigger Skew Limit with a typical upper limit of 500 ps, further underscoring its precision and reliability in synchronization tasks.
