The National Instruments PXI-6682 is a comprehensive PXI Timing and Synchronization Module designed to enhance system synchronization through IEEE 1588, IRIG-B, and GPS protocols. With part number 779929-01, this module provides precise timing capabilities vital for orchestrating synchronous events in PXI and PXI Express systems. It features a temperature-compensated crystal oscillator (TCXO) that can be disciplined to maintain long-term stability. The PXI-6682 operates within a frequency range from DC up to 1.5 MHz, generating programmable clock signals and timestamps for input events, ensuring accurate synchronization across devices.

The module is equipped with a range of connectivity options on its front panel, including a GPS antenna connector, CLKOUT and CLKIN connectors, PFI0/IRIG-B input connector, Ethernet connector, and three general-purpose PFI lines utilizing SMB connectors. It also incorporates visual indicators for GPS status, IEEE 1588 synchronization, Ethernet link activity, and Ethernet speed. The GPS antenna connector supplies 5 VDC for use with an active antenna and facilitates RF signal reception.

The PXI-6682 fits into a standard 3U PXI chassis and weighs 235 g. It maintains operational integrity within a temperature range of 0 to 55 °C, and a storage temperature range of -20 to 70 °C, while tolerating humidity levels of 10% to 90% during operation and 5% to 95% during storage. Vibration resistance is rated at 0.3 grms for operational scenarios and 2.4 grms when not in use, within a frequency bandwidth of 5 to 500 Hz.

Ideal for use with the NI Sync software, the PXI-6682 can be programmed through various NI application development environments such as LabWindows/CVI, LabVIEW, or Visual C/C++. A user manual is available for download, and interested customers are encouraged to contact a sales representative for pricing inquiries. The module comes with a three-year warranty, ensuring reliability for demanding automation and control applications.
