Overview of the Installation Procedure

“Step 1. Obtain a Keyword and Verify the Information.”
“Step 2. Remove the Outer Cover.”
“Step 3. Remove the Inner Cover.”
“Step 4. Remove the Front Panel Assembly.”
“Step 5. Remove the A19 Test Set Motherboard.”

“Step 6. Disconnect A71 and A74 Bias-Tee Combiner’s LFE Cables From the

A70 Low Frequency Extension (LFE) Board and the Ends of the LFE Cables

Connected to the IF Multiplier (IF MUX) Board.”
“Step 7. Remove the A75 Low Frequency Extension (LFE) Board.”
“Step 8. Remove Some Low Frequency Extension (LFE) Cables (8120-5014

(x1), 8120-5021 (x1), N5240-60097 (x1), and N5240-60098) From the IF

Multiplexer (IF MUX) Board.”
“Step 9. Remove Some of the Mixer Brick (MXB) Cables.”
“Step 10. Remove Some Gray Cables From the A20 IF Multiplexer Board.”
“Step 12. Remove Some Bottom-Side Semi-Rigid Test Set Cables.”
“Step 11. Remove the A70 LFE Board Bracket.”
“Step 13. Remove the A23 Mixer Brick Assembly.”
“Step 14. Assemble the A24 Mixer Brick and A22 Splitter Assemblies.”
“Step 15. Install the A23/A24 Mixer Brick Brick Assembly.”
“Step 16. Assemble the A26 and A27 Receiver Bridge Assemblies.”
“Step 17. Install the A26 and A27 Receiver Bridge Assemblies.”
“Step 18. Assemble A35/A36 Source and A43/A44 Receiver Attenuators.”
“Step 19. Install A35/A36 Source and A43/A44 Receiver Attenuators.”
“Step 20. Assemble the A72 (Port 3) and A73 (Port 4) Bias Tee Combiner

Assemblies.”

This installation requires the removal of the analyzer’s protective

outer covers. The analyzer must be powered down and

disconnected from the mains supply before performing this

procedure.
