Overview

Product overview

Key product information and technical features.

The PXIe-6674T uses the PXI Express System Timing interface and an onboard OCXO clock with 80 ppb accuracy. It supports backplane clock override, clock import, and clock export.

The module generates and routes clocks and triggers between devices in a PXI Express chassis and to other PXI and PXI Express chassis or third-party instrumentation. Trigger access includes PXI_DSTAR, PXI_STAR, and PXI_TRIG, with support for PXIe-DStarA, PXIe-DStarB, and PXIe-DStarC LVDS trigger signals.

Onboard OCXO reference with 80 ppb clock accuracy.
Generates a stable 10 MHz clock from the precision OCXO reference and a second clock from the DDS clock generation circuit.
Supports backplane clock override, clock import, and clock export.
Provides PXI_DSTAR, PXI_STAR, and PXI_TRIG trigger access, including PXIe-DStarA, PXIe-DStarB, and PXIe-DStarC LVDS trigger signals.
Routes clocks and triggers within PXI Express systems and to external chassis or third-party instrumentation.
