When NI-DAQmx detects that an NI 6608 is installed in slot 2 (or when an NI 6614 is installed in the system timing slot), NI-DAQmx automatically overrides the chassis PXI_CLX10 with the more stable oven controlled oscillator (OCXO) from the NI 6608 or NI 6614. This allows all devices in the chassis to inherit the OCXO accuracy and stability via the PXI_CLK10 signal. In a PXIe chassis, the PXIe_Clk100 signal is phase-locked to the PXI_CLK10, so PXIe_Clk100 will also inherit the OCXO accuracy and stability.

Refer to the NI 6608 documentation for more information about the stability of the OCXO.

Note Note   For the automatic override to occur in NI-DAQmx, you must put the NI 6608 in slot 2 or the NI 6614 in the system timing slot. For more information about configuring your PXI chassis, refer to the Measurement & Automation Explorer Help for PXI.
