1. Using the three medium semi-rigid SMA-to-SMA cables (labeled J), connect the LO1,
LO2, and LO3 connectors on the NI 5653 front panel to the associated LO1 IN, LO2 IN,
and LO3 IN connectors on the NI 5603 front panel.
2. Using the flexible SMA-to-SMA cable, connect the REF OUT 100 MHz connector on the
NI 5653 front panel to the CLK IN connector on the NI 5622 front panel.
3. Using the short semi-rigid SMA-to-SMA cable (labeled K), connect the IF OUT
connector on the NI 5603 front panel to the IF IN connector on the NI 5622 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.
5. Carefully complete tightening all SMA connectors to 1 N · m using an appropriate torque
wrench (not included) or torque screwdriver and SMA driver bit. Tighten only until the
wrench clicks.
