7. Check to ensure that no cables will become pinched under the hinges when folding up the
A4 and A5 assemblies.
8. Fold the A4 and A5 assemblies together as a unit into the spectrum analyzer. Use caution
to avoid damaging any cable assemblies. The standoffs on the A5 assembly must fit into
the cups on the A6 power supply top shield.
9. Fold the A2 and A3 assemblies together as a unit into the spectrum analyzer. Be sure to
fold HP-IB cable between the A3 and A4 assemblies, using the two sets of hook
and loop (Velcro) fasteners.
10. Fold ribbon cable between A3 and A4 assemblies. Take care to dress the
protective tubing as close to connector as possible, so that the tubing does not
fold with the cable. See Figure 4-10.
11. Attach ribbon cable W4 to while folding up the assemblies.
