Initial Instrument Functionality Check
1. Power on the instrument and allow the instrument to boot up, run the alignments and display
the measurement screen. The instrument will probably display a spectrum analyzer screen and
you will see the instrument sweeping.
2. There should be no alignment failures. If there are failures, investigate and fix the problem
before continuing.

Option B2X, 255 MHz Analysis Bandwidth
Wideband Analog IF Assembly Hardware Installation
1. Power down the instrument, wait until the standby light comes on, and remove the power
cord.
2. Remove the instrument side strap handles, feet, outer case, top brace front, top brace rear,
and remove the rear panel (be careful to not damage the cables), and remove the rear brace.
See the UXA Service Guide Assembly Replacement Procedure section for A22 and A23 WB
Digital IF Boards. Save all screws for reuse.
3. Disconnect the gray ribbon cable from the rear motherboard. This cable runs from the front of
the instrument, and must be disconnected to allow the Wideband Analog IF to be installed.
4. Locate the Wideband Analog IF Assembly and the N9040-60042 Flex Circuit Cable in the kit.
Install the Flex Circuit cable into the connector on the Wideband Analog IF Assembly. This flex
cable will be connected to the other flex cable in the kit later in the installation process.
5. Install the Wideband Analog IF into card cage connectors J8 and J10. See Figure 1.
6. Locate 2, 0515-1946 flat head screws in the kit and secure the board brackets to the chassis
using these screws (1). Torque to 9 inch-pounds.
Figure 1 Wideband Analog I.F. Installed in Card Cage
7. Locate the gray coax cables in the kit. Find the short cable, W46, with color code 1 on one end,
and color codes 726 on the other end. Attach the color code 1 end of the cable to the
Wideband Analog IF at J1 as shown in Figure 1. Attach the other end of the cable to the
Reference board J726.

Option B2X, 255 MHz Analysis Bandwidth
8. Locate the W45 cable with color code 2 on one end and 17 on the other end. Attach color code
2 end to the Wideband Analog IF at J2. Route the cable as shown in Figure 2, the other end of
the cable will be routed later to the A3 Digital IF.
9. Locate the W34 cable with color code 4 at one end and color code 718 at the other end. Attach
the color code 4 end to Wideband Analog IF at J4, and the other end to A16 Reference
assembly at J718.
10.Locate W41 cable with color code 17 at one end and color code 901 at the other end. Attach
the color code 17 end to the Wideband Analog IF at J17, and the other end to A15 Front End
Controller at J901. Remove cable that is on A15J901, it will be discarded after the other end of
the cable at A3J15 is removed later.
11.Locate W40 cable with color code 18 at one end and color code 15 at the other end, Attach the
color code 18 end to the Wideband Analog IF at J18. The other end of the cable will be routed
to the A3 Digital IF assembly.
12.See Figure 2 that shows the hole in the chassis the W40 cable routes through in order to
connect to A3J15.

Wideband Digital IF Assembly Hardware Installation
14.See Figure 4. Locate the Wideband Digital IF assembly in the kit. Install the assembly into the
top card slot as shown.
Figure 4 Wideband Digital I.F. Installation
15.Locate the N9040-60045 Flex Circuit cable in the kit and connect one end to the Wideband
Digital IF assembly and the other end to the Flex Cable previously installed on the Wideband
Analog IF assembly.
16.Locate the "Bracket, Flex Circuit Interconnect" in the kit. This bracket secures the flex circuit
connection you made in the previous step. See Figure 4. attach the flex cable connection to
the interconnect bracket using the two flat head screws (1), and mount the interconnect
bracket to the instrument frame using a pan head screw (2) and torque to 9 inch-pounds.

Option B2X, 255 MHz Analysis Bandwidth
17.Locate the spring clip in the kit. Install the spring clip to secure the flex circuit connection on
the Wideband Digital IF assembly.
18.Re-install the Rear Brace and the Rear Panel. An additional flat head screw, 0515-1946 is
required to secure the new Wideband Digital IF assembly to the rear panel. This flat head
screw is in the bag of screws in the kit. Torque to 9 inch-pounds
19.Re install the front top brace and use the 0515-1946 flat head screws in the kit in the
countersunk locations. Torque to 9 inch-pounds.
20.Reinstall the rear top brace and outer case, side strap handles, and feet.
21.Power up the instrument. Assure the instrument passes the auto alignments
