1.
Using the center pin of a medium semi-rigid SMA-to-SMA cable labeled C, connect the
RF OUT connector on the NI 5652 LO source front panel to the LO IN connector on the
NI 5601 RF downconverter front panel.
2.
Using the center pin of a flexible SMA-to-SMA cable, connect the REF OUT2 connector
on the NI 5652 LO source front panel to the CLK IN connector on the NI 5622 IF
digitizer front panel.
3.
Using the center pin of a short semi-rigid SMA-to-SMA cable labeled D, connect the
IF OUT connector on the NI 5601 front panel to the IF IN connector on the NI 5622 IF
digitizer front panel.
4.
Hand-tighten all SMA cable ends on the SMA connectors after the cable center pins are
correctly aligned and connected. The cable connectors should tighten without much
torque or effort. If a cable bends due to incorrect alignment, remove the cable from the
front panel connector and reconnect the cable center pin on the SMA cable to the SMA
connector.
