A11 Low Band Switch - Keysight PXA N9030A Installation Note

Frequency Range Upgrade from RF or Microwave to Millimeter Wave Frequency
Remove the Option MPB and LNP switches (if present)
12.Remove all semi rigid cables that attach to the MPB/LNP switches. Remove both ends of the
cables if possible. You will probably need to wait until the A11 Low Band switch removal step
to remove some cables completely. These cables will not be reused.
13.Remove the wire harness from the wire harness on the two bottom coax switches by
disconnecting the connectors. Leave the wire harness connected at the A15 Front End Control
assembly. This cable will be reused.
14.Remove the top switch/bracket combination. Discard
15.Remove the ribbon cable from the A11 Low Band switch connector header. Leave the ribbon
cable connected at the A15 Front End Control assembly. This cable will be reused.
16.Remove the middle switch/bracket. The attenuator will probably still be attached. Discard
17.Remove the bottom switch/bracket. Discard.
Remove the A11 Low Band Switch
18.Remove all semi rigid cables from the Low Band Switch.
19.Remove the two screws holding the Low Band switch bracket to the chassis and remove the
Low Band Switch/bracket
Remove the A12 YTF assembly
20.Disconnect all semi rigid cables from the YTF. If Option MPB/LNP was present, you already
removed these cables. Discard the cables.
21.Disconnect the wire harness from the YTF header. This wire harness will be reused.
22.Remove the YTF by removing the 4 mounting screws on the instrument chassis. If the gap pad
is stuck to the instrument frame, remove the gap pad.
Replace the A15 Front End Controller (only if the hard ware ID is 42.
See the Analyzer Information section previously).
23.Remove all cables from the A15 Front End Controller
24.Remove the Front End Controller assembly.
25.Locate the Front End Controller in the kit, install this assembly, and replace all cables. Some of
the cables will need to removed again, however, reattaching the cables prevents loss of cables
and aids in cable routing.
Reposition the A20 YTO Assembly
26.Remove and discard the semi-rigid cable from the YTO (W20).
27.Remove the two screws holding the YTO to the bottom of the chassis, and remove the YTO.
28.Re-attach the YTO to the bottom of the chassis using the pair of mounting holes approximately
2.5 cm further back from the original mounting holes. This allows additional room, between
the YTO and the YTF, that is necessary when installing the YTF cable later.
