Option BAB Hardware Retrofit Kit

Introduction

The Option BAB retrofit kit provides all the parts and instructions necessary to install

the APC 3.5 input connector into the Agilent E4440A spectrum analyzer. The Option

BAB is licensed for one instrument model number/serial number combination. The kit

will only function on the instrument it was ordered for.

NOTE The instrument must be performance tested to assure it meets

specifications following the hardware installation. It is possible that

installing the input connector and different input cable might cause

frequency response to be out of specifications. The PSA Series

Performance Verification and Adjustment Software must be used. All

adjustments are automated. This software is included in the Option

OBW service documentation and performance test and adjustment

software package.

Installation Procedure

Install the Option BAB RF Input Connector

1. Remove the APC 3.5 input connector assembly from the kit.

2. Loosen, but don’t remove the semi-rigid cable that is attached to the input connector

assembly.

3. Install the connector assembly into the instrument. Attach the semi-rigid cable to the

A14 attenuator, but don’t tighten

4. Using the T-10 driver, install the 2 screws from the kit that secure the input

connector bracket to the deck. Torque to 9 inch pounds.

5. Using a 5/16 inch wrench, tighten the semi-rigid cable at the attenuator and the

input connector. Torque to 10 inch pounds.

Replace the Front Frame

1. Position the front frame on the deck using the alignment bosses on the deck.

Remember to tuck the ribbon cable under the fans when pushing the frame onto the

deck. This will insure proper airflow to cool the instrument.

2. Using the T-10 driver, replace the 7 screws that secure the front frame to the deck.

Torque to 9 inch pounds.

Replace the Top Brace and Outer Case

1. Refer to Figure 2. Carefully position the top brace on the deck. The alignment pin at

the center of the web/fan assembly must mate with the alignment hole on the top

brace. Make sure that no coaxial cables will get pinched underneath the brace.

2. Use the T-10 driver to replace and tighten the top screws first; then replace the side

screws. Torque to 101 Ncm (9 in-lb).

3. Refer to Figure 1. Slide the instrument cover back onto the deck from the rear. The

seam on the cover should be on the bottom. Be sure the cover seats into the gasket

groove in the front frame.

4. Replace the four rear feet onto the rear of the instrument. Torque to 236 Ncm (21

in-lb).

5. Use the T-20 driver to replace the handles. Torque to 236 Ncm (21 in-lb).

6. Replace the four bottom feet by pressing them into the holes in the case and sliding

them in the opposite direction of the arrows until they click into place. Note that the

feet at the front have the tilt stands.

Turn the Instrument On

Plug in the instrument and apply power. Continue with the next procedure to install the

option designator and license keyword for this option.
