Option EXM, External Mixing Upgrade Kit
Add Cables to A13 Front End and A15 Front End Controller
NOTE
This procedure only applies to millimeter wave EXAs (frequency range
options 532 and 544).
1.
Locate the flexible coax assembly in the Opt EXM Cable Kit with Markers. This is cable W26
and should be labeled “8120-2025” and have the ends labeled “903” and “13”
2.
Connect the end of W26 that is labeled “903” to A15J903.
3.
Connect the end of W26 that is labeled “13” to A13A1J13. J13 is one of the connectors along
the top side of A13. Torque the cable nut to 10 inch-pounds.
4.
Remove the SMA termination on A13A1J8. A13A1J8 is to the left of A13A1J13.
5.
Locate semi-rigid coax cable, part number N9020-20198, in the upgrade kit. This is W28.
Connect the end with the SMA male connector A13A1J8, with the SMA female connector
pointing towards where the front panel would be. The long, straight section of W28 should be
parallel to the casting of the A13 Front End and level. Refer to Appendix Figure 7, “Orientation
of W28 in a Millimeter Wave EXA,”. Note that W26 is routed below W28. Torque the cable nut
to 10 inch-pounds.
