USED National Instruments PXI-6653 Timing and Synchronization Module

Fully tested & working used National Instruments PXI-6653 high-stability timing and multi-chassis synchronization module (part number 778715-01). Designed for precision PXI system timing, it integrates a high-stability 10 MHz OCXO (50 ppb) reference oscillator, low-skew (<1 ns) PXI star trigger controller, and a DDS clock generator (1 MHz–105 MHz). Features front-panel CLKIN/CLKOUT and 6×PFI (SMB) ports for flexible clock/trigger routing. Enables tight synchronization across multiple PXI chassis and modules for high-channel-count test systems. Compatible with NI-SYNC driver software and LabVIEW. Fully calibrated, tested, and in excellent working condition.
