Estimated Installation Time:. . . . . . . . . . . . . . . . . . . . . . . 2.0 Hours
Estimated Verification Time: . . . . . . . . . . . . . . . . . . . . . . 3.0 Hours
Additional Recommended Task: . . . . . . . . . . . . . . . Agilent recommends a full calibration be performed to verify instrument specifications
To ensure that this newly installed option is functioning properly, the procedure that follows includes the requirement of performing certain adjustments and performance verification tests. However, the completion of these tests does not guarantee that the instrument meets all advertised specifications.
Software is required to perform the required adjustments, and can be used to automate the performance verification testing.
Information on how to obtain this software can be found at: www.agilent.com/find/calibrationsoftware
While Agilent does recommend that a full calibration be performed after the installation of this upgrade, the end user must ultimately determine whether they want this service or not. If a full calibration is required, arrangements regarding the level of calibration must be made between the end user and the calibration provider.

Procedure
Removing the Dress Cover
, disconnect the analyzer from ac power (1) .
2. Remove any adapters or cables connected to the front panel (2) .
3. Position the handle (4) to the rear of the analyzer.
4. Carefully place the analyzer on the work surface with the front frame (3) facing down.
5. Remove the four screws (5) that hold the rear frame (6) and dress cover (7) in place.
6. Remove the rear frame (6) and dress cover (7) by sliding them towards the rear of the analyzer.

Extending the Front Frame
The front frame assembly can be extended from the instrument without detaching any connections or removing the chassis cover.
1. Referring to Figure 2 , with the instrument still on its face, remove the five screws
(1) , two on the bottom side and three on the top of the instrument, that secure the front frame to the RF assembly and chassis cover.
2. Place the instrument with the top side facing up and remove the remaining two screws (2) that secure the front frame subpanel to the chassis.
3. Slide the front frame forward until it catches on the tabs on the sides of the chassis.
Removing the Front Frame
Figure 2 Front Frame Assembly Removal
1. Disconnect the ribbon cable (3) from the front panel interface board.
2.
Carefully pull the sides of the front frame subpanel away from the chassis and over the tabs on the chassis.
3.
Slide the front frame forward to disengage from the chassis assembly.

Removing and Replacing the RF Input connector
1. Rotate the analyzer so the right side is resting on the table.
, locate W6 (1) . W6 is a semi-rigid coax cable connected between the A8A5 input attenuator (2) and the A8J1 input connector (3) .
Figure 3 Replacing the Input Connector and Cable
3. Remove W6 (1) from A8J1 (3) , then from A8A5 (2) . Discard the removed cable as it will no longer be needed.
4. Remove the A8J1 input connector from the midweb (4) .
5. Attach the APC 3.5 mm input connector included in this kit to the midweb (4) using the two 3.0 mm screws provided in the connector kit.
6. Connect the new W6 semi-rigid cable, included in the kit, between the A8A5 input attenuator (2) and the APC 3.5 mm input connector (3) . Tighten the SMA connectors to 8.5 inch pounds.
8 Installation Note E4407-90041
Replacing the Front Frame
1. Align the front frame subpanel rails with the chassis as shown in
, connect the ribbon cable (3) to the front frame assembly.
3.
Carefully slide the front frame toward the chassis, assuring the ribbon cable is not pinched between assemblies, and the RF input connector lines up correctly with the opening in the front frame.
NOTE Make sure the water seal is still in place around the input connector (and around the A2 tracking generator connector if the instrument is an Option 1DN) before reinstalling the front frame assembly.
, replace the five screws (1) , and the two screws (2) that secure the front frame to the chassis.
Tighten them to 9 inch-pounds.
Replacing the Dress Cover
, place the spectrum analyzer on the work surface with the front frame (3) facing down.
2. Replace the instrument outer case and rear frame assembly (6) , matching the grill (8) on the bottom of the case to the bottom of the analyzer.
3. Fit the leading edge of the case completely into the slot (9) on the back of the front frame assembly.
4. Replace the four screws (5) to fasten the rear frame to the instrument. Tighten them to 21 inch-pounds.
Firmware Revision Verification
1. Turn on the analyzer and wait for the power-on alignments to complete. Check that there are no error messages displayed.
2. Press System , More , Show System . Make a note of the firmware revision and see if Option B72, Expansion Memory, is listed on the display.
4. If your firmware revision is prior to A.06.00, you must update your analyzer firmware before the license key can be activated.
5. If Option B72, Expansion Memory is installed, you should update the instrument firmware to the latest version using one of the following methods:
• Download the instrument firmware via the world-wide web at http://www.agilent.com/find/esa_firmware. This entire process of updating firmware will take approximately 45 minutes.
Note: If you are upgrading an EMC analyzer, go to www.agilent.com/find/emc_firmware.
• Receive the latest firmware update disk set by ordering upgrade Option UE2.
Note: Special instructions in the Agilent ordering configurator should have made you aware of Option UE2 in case access to the internet wasn’t available.
6. If Option B72, Expansion Memory is not installed, you should update the instrument firmware to version A.07.06. This is the latest version for instruments that do not have Option B72 installed.
• Download the instrument firmware via the world-wide web at http://www.agilent.com/find/esa_firmware_std-mem.
This entire process of updating firmware will take approximately 45 minutes.
• Order upgrade Option B72, which includes the expansion memory and the latest ESA firmware update disk set.
