Initial Instrument Functionality Check
Power on the instrument and allow the instrument to boot up. Run an alignment and display the
measurement screen. (The instrument will probably display a spectrum analyzer screen and you will
see the instrument sweeping.)
There should be no alignment failures. If there are failures, investigate and fix the problem before
continuing.
Before you disassemble the instrument, turn the power switch to Standby. After the instrument
has completely shut down, unplug the instrument. Failure to unplug the instrument can result in
personal injury.
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.

2. Save this SMA termination. It will be installed on the front panel EXT mixer connector.
3. Locate semi-rigid coax cable, part number N9020-20167, in the upgrade kit. This is W29.
Connect the end with the SMA male connector A13A1J8, with the SMA female connector
pointing towards where the front panel would be. The long, straight section of W29 should be
parallel to the casting of the A13 Front End and level. Refer to Figure 6. Torque the cable nut to
10 inch-pounds.

Add EXT MIXER Connector and Cable to Front Frame Assembly
1. Locate the SMA female to SMA female connector (1250-1666), ¼” lockwasher (2190-0067),
and ¼” hex nut (2950-0223) in the kit. If the SMA connector includes hardware, discard that
hardware and use the 2190-0067 lockwasher and 2950-0223 hex nut included in this kit.
2. Remove the hole-plug in the top-most hole in the upper right corner of the front frame
assembly. This hole will be labeled “EXT MIXER”.
3. Insert the SMA female to SMA female connector in the hole in the front frame assembly from
the front of the assembly. The hex feature on the connector should engage with the recess in
the front frame assembly. Refer to Figure 7. Secure the connector using the ¼” lockwasher
and ¼” hex nut from the rear. Torque to 21 inch-pounds.
Figure 7 Attaching SMA Female Connector
4. Locate the SMA termination removed on page 11 step 2. Attach this SMA termination to the
front panel EXT Mixer SMA connector.
5. Locate the External Mixing, Front Panel semi-rigid coax assembly in the kit, part number
N9020-20166. This is W30. Note that this cable is symmetrical; either end can be connected to
the front-panel connector.
6. Connect one end of W30 to the SMA female connector as shown in Figure 8.
7. Orient W30 so that the cable is parallel with the front frame. The top of the connector should
be approximately level with the top of the shield over the Front Panel Interface board speaker.
Refer to Figure 9. Torque the cable nut on the Ext Mixer connector to 10 inch-pounds.

3. Refer to Figure 12. When the front panel is installed, cables W29 and W30 typically do not
align perfectly. This is OK since the cables are slightly flexible. If additional alignment is
needed loosen W29 at A13J8 and re-position.
4. Refer to Figure 13. Align and connect cables W29 and W30. Hand-tighten the nut.
