PXIe-5663/5663E: Connect the external signal to the PXIe-5652 REF IN/OUT connector. Connect the REF OUT2 connector (if it exists) on the PXIe-5652 to the PXIe-5622 CLK IN terminal. PXIe-5665: Connect the external signal to the PXIe-5653 REF IN connector. Connect the 100 MHz REF OUT terminal on the PXIe-5653 to the PXIe-5622 CLK IN connector. If your external clock signal frequency is set to a frequency other than 10 MHz, set the SetFrequencyReferenceFrequency(string, double) method according to the frequency of your external clock signal.
PXIe-5668: Connect the external signal to the PXIe-5653 REF IN connector. Connect the LO2 OUT on the PXIe-5606 to the CLK IN connector on the PXIe-5622. If your external clock signal frequency is set to a frequency other than 10 MHz, set the SetFrequencyReferenceFrequency(string, double) method according to the frequency of your external clock signal.
PXIe-5644/5645/5646, PXIe-5820/5840/5841/5842/5860: RFmx locks the device to the signal at the external REF IN connector. PXIe-5830/5831/5832: For PXIe-5830, connect the PXIe-5820 REF IN connector to the PXIe-3621 REF OUT connector. For PXIe-5831, connect the PXIe-5820 REF IN connector to the PXIe-3622 REF OUT connector. For PXIe-5832, connect the PXIe-5820 REF IN connector to the PXIe-3623 REF OUT connector. For PXIe-5830, lock the external signal to the PXIe-3621 REF IN connector. For PXIe-5831, lock the external signal to the PXIe-3622 REF IN connector. For PXIe-5832, lock the external signal to the PXIe-3623 REF IN connector.
PXIe-5831 with PXIe-5653: Connect the PXIe-5820 REF IN connector to the PXIe-3622 REF OUT connector. Connect the PXIe-5653 REF OUT (10 MHz) connector to the PXIe-3622 REF IN connector. Lock the external signal to the PXIe-5653 REF IN connector.
PXIe-5832 with PXIe-5653: Connect the PXIe-5820 REF IN connector to the PXIe-3623 REF OUT connector. Connect the PXIe-5653 REF OUT (10 MHz) connector to the PXIe-3623 REF IN connector. Lock the external signal to the PXIe-5653 REF IN connector.
PXIe-5840 with PXIe-5653: Lock to the signal at the REF IN connector on the associated PXIe-5653. Connect the REF OUT (10 MHz) connector on the PXIe-5653 to the PXIe-5840 REF IN connector.
PXIe-5860:Lock to the signal at the REF IN connector on the PXIe-5860.
