National Instruments PXI-6652 PXI Timing and Synchronization Module

Featured with 711 nHz resolution and DC to 105 MHz high-resolution clock generation, the National Instruments PXI-6652 (Part Number:  778726-01) is a PXI Timing and Multi-Chassis Synchronization Module. This module comes with the capability to import/export triggers to the PXI backplane, drive PXI start trigger lines, and generate a TCXO 10 MHz reference clock with alleviated stability for instrumentation. The NI PXI 6652 can also be used to enhance the instrument’s accuracy within a system or for the synchronization of several PXI systems together. It is equipped with 1 3U PXI slot, and a 50 Ω SMB male front panel connector.

When this module is inserted in slot 2 of a PXI chassis, the PXI-6652 module can supersede the built-in 10 MHz reference clock on a PXI chassis. The clock preciseness is increased to 1 ppm with the NI PXI-6652 module.

The Clock Input (CLKIN) connector provided on the front panel of the NI PXI-6652 supplies the module with a clock. This clock can be routed to the onboard PLL programmatically for its utilization as a reference or routed to the PXI backplane (PXI_CLK10_IN) directly for distribution to other modules sharing the same chassis. This Timing and Synchronization Module comes equipped with a Clock Output (CLKOUT) connector. The CLKOUT can be routed programmatically from the temperature-compensated crystal oscillator (TCXO), backplane clock (PXI_CLK10), direct digital synthesis (DDS), or oven-controlled crystal oscillator (OCXO).

The National Instruments PXI-6652 features Programmable Function Interfaces (PFI) <0..5>. Each of these connectors can be used as an input or output. In addition, the user can configure the PFI 0 as a clock input for the internal synchronization of other signals. With this timing and multi-chassis synchronization module, the user can program PFI connections in their individual capacity. The National Instruments PXI-6652 can generate clock signals using either its onboard DDS chip or a precise 10 MHz oscillator.

The PXI-6652 is run using the NI-Sync driver software which can be programmed with software packages or application development environments (ADEs) such as LabVIEW, LabWindows/CVI or Microsoft Visual C++. The NI device measures 3.9 x 6.3 in. in physical dimensions.

The PXI-6652 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the PXI-6652 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the PXI-6652 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
