Introduction
This procedure can be used to retrofit Low Emissions, Option 060, into an E4401B, E4402B, E4404B, E4405B, or E4407B
spectrum analyzer. Separate kits are provided for each model number. Several kits contain two or more versions of a part, such
as a nameplate or connector label, so that each of these kits can support all options the analyzer may already have. As a result,
not all parts in each kit will be used.

Procedure
WARNING Before you disassemble the instrument, turn the power switch to Standby and unplug the
instrument. Failure to unplug the instrument can result in personal injury.
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic
assemblies should be performed at a static-safe workstation. Refer to the documentation that pertains to
your instrument for information about static-safe workstations and ordering static-safe accessories.
Removing the Dress Cover
1. Referring to Figure 1, disconnect the analyzer from ac power (1).
2. Remove any adapters or cables (2) connected to the front frame.
3. Carefully place the analyzer on the work surface with the front frame (3) facing down.
4. Position the handle (4) as shown.
5. Remove the four screws (5) that hold the rear frame and dress cover in place.
6. Remove the rear frame (6).
7. Pull the dress cover (7) off towards the rear of the analyzer.

Removing the Chassis Cover
1. Lay the analyzer flat as shown in Figure 2.
2. Remove the 17 screws (2) and (3) attaching the chassis cover to the chassis. Note that the number of screws attaching
the chassis cover may vary with option mixes.
3. Remove the chassis cover (1) from the chassis.

A1 Front Frame Assembly
CAUTION Use ESD precautions when performing this replacement procedure.
Extending the Front Frame
The A1 front frame assembly can be extended from the instrument without detaching any connections.
1. With the instrument still on its face, remove the two screws (1) on the bottom side of the instrument, that secure the front
frame to the RF assembly.
Figure 3 A1 Front Frame Assembly Removal
2. Refer to Figure 3. 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.

Installation Note E4401-90456
14
Removing the Front Frame
To completely remove the A1 front frame assembly, refer to Figure 3 and complete the “Extending the Front Frame”
procedure, then continue with the following steps:
1. Refer to Figure 4. Disconnect the ribbon cable (1) from the A1A1 front panel interface board. Analyzers with Option
B7B will have a second ribbon cable connecting to A1A1. Disconnect the second ribbon cable if present.
Figure 4 Front Frame Ribbon Cable
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.

Installation Note E4401-90456 15
Removing the A1A2 Display
Refer to Figure 5 for the following procedure.
Figure 5 A1A2 Display Removal
1. Place the front frame assembly face down on the work surface.
2. Disconnect the two 2-wire backlight cables (1) from the front panel interface inverter board.
3. Disconnect W3 ribbon cable (2) from the front panel interface board.
CAUTION The W3 display ribbon cable connector (2) is delicate. With a small screwdriver or similar tool, gently
push the lock tabs out from the back of the connector. Excessive force on the locking tab can break the
retaining clips, and if broken, board replacement will be necessary.
4. Remove the four screws (3) securing the display (in a bracket) (4) to the front frame.
5. Carefully lift the display out of the front frame assembly.

Removing the A1A1 Front Panel Interface Board
Figure 6 A1A2 Display Removal
1. Remove the volume knob and the RPG knob.
TIP You may need to exert considerable force in order to remove the RPG knob. It may be necessary to pry
it off using a screwdriver as shown in Figure 6.
2. Refer to Figure 7. Remove the four screws (10) that secure the A1A1 front panel interface board (11) to the front frame.
3. Remove the front panel interface board from the front frame assembly.
NOTE There is a water-seal gasket placed around the volume control shaft that will need to be repositioned during
the replacement procedure.

Removing the Keypad Flex Circuit
Figure 7 Front Frame Assembly Parts
1. Refer to Figure 7. Remove the support bracket (3).
2. Remove the 6 screws (8) securing the subpanel assembly (9) to the front frame (6).
3. Remove the subpanel assembly (9).

Attaching the Nameplate to Front Frame
1. Locate the nameplate in the kit. The nameplate is labelled with the analyzer product number (for example, “E4404B”) and
the analyzer’s frequency range. Some kits contain two nameplates, identifying different frequency ranges for the analyzer.
For example, the kit for the E4404B will have one nameplate for the standard instrument where the frequency range is
9 kHz to 6.7 GHz and another nameplate for Option UKB, where the frequency range is 100 Hz to 6.7 GHz. Choose the
nameplate that is appropriate for the analyzer being retrofitted.
2. Lay the new front frame included in the kit on the table with the front facing up. Locate the pocket (2) above the display
opening where the nameplate will go. Refer to Figure 8.
3. Clean the nameplate pocket (2) with alcohol.
4. Remove the backing (3) from the nameplate (4) and press the nameplate into the pocket (2).
Figure 8 Nameplate Replacement

Installation Note E4401-90456 19
Attaching the Connector Label and Connector Covers to Front Frame
1. Locate the connector label in the kit. The connector label has holes to accommodate the various front panel connectors and
the volume control. The frequency range of the analyzer appears near the hole next to the INPUT connector. Some kits
contain two or more connector labels identifying different frequency ranges and connector configurations. Choose the
connector label that is appropriate for the analyzer being retrofitted.
NOTE For the E4407B, there are two connector labels for each frequency range. One label of each pair is for
analyzers which also have external mixing, and the other label is for analyzers which do not have
external mixing. Be sure to choose the correct label.
2. Remove the backing (2) off the new label as shown in Figure 9.
3. Align and install the label by placing a finger in the RF OUT and VOLUME holes. Observe the alignment of the INPUT
and PROBE POWER holes (3).

4. Install the two connector covers from the front panel by pinching them from the sides (4) and installing them through the
front of the assembly. See Figure 10.
TIP It may be helpful to trim off about 2 mm of the tabs (5) on the connector covers prior to reinstalling
them. This will help in aligning the covers. See Figure 10.
Figure 10 Connector Covers
5. Align the connector covers so they open downward as shown.
6. Turn the front frame over so that the inside of the front frame is facing up.
7. If the analyzer is equipped with a tracking generator, a Type-N EMC Seal (included with the front frame) must be installed
onto the inside of the front panel behind the RF OUT connector hole. Remove the adhesive backing from the seal and press
it into the front frame pocket. The foiled edges must make contact with the top and bottom of the frame pocket.
8. If the analyzer is an E4401B, a Type-N EMC Seal (included with the front frame) must be installed onto the inside of the
front panel behind the INPUT connector hole. Remove the adhesive backing from the seal and press it into the front frame
pocket. The foiled edges must make contact with the top and bottom of the frame pocket.
