Installation Procedure for the Upgrade
Step 5. Remove Some Existing Cables
1. Place the analyzer bottom-side up on a flat surface.
Remove the following cables. To see an image showing the location of these
cables, click the Chapter 6 bookmark “Bottom RF Cables, Standard 2-Port
Configuration, Option 200” in the PDF Service Guide1.
These RF cables may be discarded - they will not be reinstalled.
— W3 (N5232-20013) A21 MASSY to A25 test port 1 bridge coupler (thru)
— W5 (N5232-20016) A25 test port 1 bridge coupler (arm) to A24 mixer brick
— W6 (N5232-20014) A21 MASSY to A24 mixer brick
— W4 (N5232-20011) A21 MASSY to A26 test port 2 bridge coupler (thru)
— W8 (N5232-20015) A26 test port 2 bridge coupler (arm) to A24 mixer brick
— W7 (N5232-20012) A21 MASSY to A24 mixer brick
These cables must be saved - they will be reinstalled.
— W2 (N5232-20082) A21 MASSY to test set deck cable bracket
— W1 (top-side cable) (N5235-20040) A4 13.5 GHz Source Synthesizer board
to test set deck cable bracket
— W10 (N5232-20081) A24 mixer brick to test set deck cable bracket
Step 6. Assemble the A29 and A30 Source Attenuator Assemblies
Refer to
for this step of the procedure. New parts are listed in
1. Gather two source attenuators (33321-60082) and install a ribbon cable
(8121-0982) on each.
2. Install bracket N5235-00013 on the port 1 source attenuator, and bracket
N5235-00012 on the port 2 source attenuator using two screws
(0515-0372) with each bracket. Use a T-10 TORX driver set to 9 in-lbs to
tighten all screws.
Leave the gray flexible cables, the wire harnesses, and the ribbon cables
connected where possible. Any that are removed should be labeled for
reconnection later.
Be careful not to damage the center pins of the semirigid cables. Some
flexing of the cables may be necessary but do not over-bend them.
When removing a cable, also remove the plastic cable clamp, if present. It
is normal for some of the cable clamp’s adhesive to remain.
