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

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).

E4440-90092 11
Installation Procedure
Install the Option Designator and License Keyword
NOTE Option designator BAB and the license keyword must be entered into
instrument memory before the instrument will recognize the option.
1. On the instrument front panel press: System, More, until the Licensing softkey is
visible. Press Licensing and Option. This will activate the alpha editor menu. Use the
front panel alpha editor to enter the upper-case option designator BAB.
Press the Enter key.
Note that BAB now appears on the Option key.
2. Press License Key. The license key number is a hexadecimal number that will require
the entry of both letters and numbers. The license keyword appears on the license
keyword certificate included in the kit. Use the alpha editor to enter the letters and
the front panel numeric keypad to enter the numbers. Your entry will appear in the
active function area of the display. If you make a typing error, use the backspace key
to correct the error. Check the license key number you entered. Press Enter, Activate
License.
3. Cycle instrument power and allow the instrument to perform the auto align routine.
Performance Tests Required
NOTE This procedure requires the use of software included in Option 0BW,
PSA Service Guide and Performance Tests and Adjustment Software.
This option is available through your local Agilent Technologies Sales
and Service Office.
1. Load the PSA Series Performance Tests and Adjustment Software on your PC.
2. Since the cal sticker was probably broken when the instrument was taken apart, and
a different input connector and cable placed in the signal path, it is recommended
that all performance tests be performed. At minimum, perform the Frequency
Response performance test.
