Option BBA, Analog Baseband I/Q Inputs Upgrade Kit
8. Carefully slide the switch assembly towards the back of the instrument. Assure the cables in
the switch ports are free to slide out.
9. Slightly lift the two semi-rigid cables above the switch assembly and pull the switch away
from the chassis.
Installation of the Flex Ribbon Cable
1. Locate the 8121-1683 flex ribbon cable in the kit. Push the rubber cable protector against the
cable connector on the end of the cable that does not have the ferrite block. When installed,
the end of the cable with the ferrite block will attach to the front panel.
2. Refer to Figure 12. Notice the flex cable orientation. The cable is routed between the chassis
and the colored wire harness. The connection side of the cable is pointing outward. The switch
assembly ribbon cable (if present) and low band assembly ribbon cables are on the outside of
the flex ribbon cable.
Figure 12 Flex Cable
3. Install the flex ribbon cable onto the BBIQ main board. Slide the flex ribbon cable through the
slot in the chassis nearest the BBIQ main board. Make sure the rubber cable protector is
against the cable connector. Assure the pins of the BBIQ main board connector are aligned
with the ribbon cable connector and carefully make the connection.

Installation Note N9030-90077 19
Option BBA, Analog Baseband I/Q Inputs Upgrade Kit
4. Assure the flex ribbon cable is flat against the chassis and partially behind the switches (if
present). Also ensure there is a very small bit of slack in the flex ribbon cable where it goes
through the chassis so the cable can easily be removed from the BBIQ main board.
Instruments with the Switch Assembly
1. Position the switch assembly, removed earlier in its mounting location, being careful to align
the semi-rigid cable with the switch ports. Assure the lower threaded mounting tab is behind
the low band switch bracket. Do not attach the switch bracket with screws yet.
2. Assure the gray coax cable is routed under the switch bracket, laying on top of the switch
body.
3. Reinstall W52 and tighten W54 and W53. Attach cables W2 and W8. Reinstall W51. Torque to
10 inch-pounds.
4. Attach the switch assembly using the 3 screws removed previously

Install the BBIQ Coax Cable
1. Locate coax cable 8121-1401 and cable labels in the Opt BBA cable kit, N9030-60018.
2. Label one end of the cable with marker 707 and the other end with 101.
3. Remove the wire cable holder from the side frame.
4. Refer to Figure 13 for cable routing diagram.
5. Install the “707” end of the 8121-1401 cable to J707 on the Reference board.
6. Route the cable as shown under the attenuator brackets.
7. Install the “101” end of the 8121-1401 cable to J101 on the BBIQ Main board.
8. Replace the wire cable holder. Assure the cables are routed to avoid pinching when the top
brace is re-installed.
