Export a Frequency Reference
You can export onboard reference of the PXI-5610 upconverter module to other benchtop instruments or PXI modules.
The 10 MHz reference signal from the upconverter module onboard OCXO is always available on the 10 MHz OUT front panel connectors. Both connectors transmit replicas of the upconverter module 10 MHz frequency reference signal, 180 degrees out of phase with each other. If the upconverter module has been configured to lock to an external reference signal, then the signal generated at the 10 MHz OUT upconverter module front panel connector is also locked to the specified reference.
You can also configure the upconverter module to drive the 10 MHz PXI backplane clock with its highly accurate onboard Reference Clock. This option is available only when the upconverter module is installed in PXI Slot 2 on a PXI chassis. The PXI-5610 cannot drive the 10 MHz PXI backplane clock in a PXI Express chassis. You can also configure the upconverter module and the NI RF signal generator to lock to an external Reference Clock signal attached to the REF IN connector on the upconverter module front panel.

The timebases of both RF signal generator hardware modules (the AWG module and the upconverter module) must be frequency-locked to a common 10 MHz Reference Clock.

The PXI-5610 onboard 10 MHz OCXO Reference Clock offers superior accuracy and phase noise specifications to the 10 MHz reference built into most PXI chassis. When you install the PXI-5610 in Slot 2 of a PXI chassis, you can use this reference to drive the 10 MHz PXI backplane clock and serve as the master reference for the PXI system.
