Digital Demodulation Hardware Retrofit Kit
Digital Demodulation Hardware Retrofit Kit
Introduction
This kit is required to retrofit the digital demodulation hardware on early Agilent
E4440A spectrum analyzers with serial prefixes less than or equal to those shown above.
The kit contains the latest third converter and reference assembly in addition to the
Option B7J electronic attenuator and cables. Instruments with serial prefix greater than
4042 do not require the third converter and reference assembly, so these instruments
can be upgraded with the Option B7J kit. The option is licensed to one instrument model
number/serial number combination. The kit will function only in the instrument for
which it was ordered.
NOTE 1. The installation of this kit requires that some re-adjustment and
performance testing be performed in order to assure the new option is
functioning properly. This installation note includes a list of required
adjustments and performance tests. Completing the list of required
performance tests does not guarantee the instrument meets all
specifications.
NOTE 2. The instrument end user must determine whether they need a full
instrument calibration following the installation of the kit. If full
calibration is required, arrangements regarding the level of calibration
must be made between the end user and the calibration provider.

Installation Procedure
Installation Procedure
1. Perform the following procedures in order:
a. Remove the instrument outer case.
b. Remove the instrument top brace.
c. Install the Option 071 retrofit kit.
d. Install the instrument top brace and outer case.
e. Install the option designator key.
f. Load firmware if existing firmware is A.02.04 or earlier.
g. Initialize calibration constants for the new hardware.
h. Perform the adjustments and performance tests.
For assistance at any time during this procedure, get in touch with your nearest Agilent

Remove the Outer Case
CAUTION If the instrument is placed on its face during any of the following
procedures, be sure to use a soft surface or soft cloth to avoid damage to
the front panel, keys, or input connector.
1. Disconnect the instrument from ac power.
2. Refer to Figure 1. Remove the two handles on the sides of the instrument as shown.
Use the T-20 driver to loosen the screws that attach each handle (1). Remove the
handles.
3. Remove the four bottom feet (2). Lift up on the tabs on the feet, and slide the feet in
the direction indicated by the arrows.
4. Remove the four screws (3) that hold the rear feet (4) in place.
5. Pull the instrument cover (5) off toward the rear of the instrument.

Installation Procedure
Remove the Top Brace
1. Refer to Figure 2. Use the T-10 driver to remove the top screws (3) (one screw is
under the security label), and the side screws (2) attaching the top brace (1) to the
deck.
2. Remove the top brace from the deck.

Installation Procedure
Attach the Attenuator to the Bracket
1. Refer to Figure 3. Install the electronic attenuator onto the attenuator bracket using
four of the screws contained in the kit; torque to 101 Ncm (9 inch pounds).
Figure 3 Attach the Attenuator to the Bracket

Installation Note E4440-90596 9
Installation Procedure
Install the Attenuator
1. Figure 4 shows the RF section and parts locations. Locate the RF section on the right
side of the instrument.
Figure 4 Remove Cables
CAUTION In the following step 2, use a 7/16-inch wrench on one of the wrench
flats at the ends of the filter to prevent the filter body from rotating
when removing the cable. Cables can be damaged if the low pass filter
is allowed to rotate when loosening or tightening the cable connector.
2. Locate and remove cable W36 (RYTHM to low pass filter), using the 5/16-inch
wrench. Discard this cable, since it will be replaced by another cable.
3. Connect one end of ribbon cable W53, contained in the kit, to the ribbon cable header
on the electronic attenuator assembly. Make sure the alignment ribs on the cable
connector line up with the keying feature on the cable header.
4. Figure 5 shows installed attenuator and cable routing. Slide the electronic attenuator
assembly into the instrument and secure with two screws included in the kit.

Installation Procedure
Figure 5 Install the Attenuator
5. Select the E4440-20110 semi-rigid cable from the kit. This cable is reference
designator W51, shown in Figure 5. Connect the cable between the RYTHM and the
electronic attenuator. Torque to 112 Ncm (10 in-lb).
6. The remaining semi-rigid cable in the kit is the E4440-20109 having cable reference
designator W52. Connect this cable between the low pass filter and the electronic
attenuator. Use the 7/16-inch wrench to hold the filter in place when tightening the
cable connector to 112 Ncm (10 in-lb).
7. Carefully route the electronic attenuator ribbon cable (W53) to the front end driver
J13 as shown in Figure 5. Plug the ribbon cable into front end driver connector J13
(option module).
8. Locate the A11 Reference assembly and the A10 Third Converter assembly by looking
at the silk-screen diagram on the top brace. Notice that the color codes of the cables
that attach to these assemblies are shown on the top brace and are silk screened on
the circuit boards near the connectors. Also notice how the cables are routed, so you
can reproduce the routing after you replace these two assemblies.
9. Remove and replace the reference assembly.
10.Remove and replace the third converter.
