RSA3303A & RSA3308A Service Manual
Procedures for RF1 Modules on the Instrument Bottom
Read the
Access Procedure
on page 6--22 before proceeding. The procedures are
presented in the following order:
H
A100 Interconnection board
H
Step attenuator 2 (for RSA3308A)
H
Input relay and step attenuator 1 and 2 (for RSA3303A)
H
Input relay, programmable band-pass filter (YTF), step attenuator 1, and
band relay (for RSA3308A)
1.
Assemble equipment and locate module to be removed:
a. You will need a #1 Phillips screwdriver (Items 1 and 2).
b. Locate the A100 Interconnection board in the locator diagram Bottom
modules -- RF1 , Figure 6--9, page 6--19.
2.
Orient the analyzer:
Set the analyzer so its top is down on the work surface
and its left side is facing you.
3.
Remove the A100 Interconnection board: See Figure 6--24. Also see
Figure 6--38 (RSA3303A) or 6--39 (RSA3308A) for cable interconnection.
a. Unplug the cable at J100 on the A100 board.
b. Do one of the following steps depending your instrument:
H
For RSA3303A . Unplug the cables at J120, J230, and J130 on the
A100 board.
H
For RSA3308A . Unplug the cables at J111, J120, J110, J130, and
J280 on the A100 board.
c.
Unplug the SMB cables at J300 and J302 on the A100 board.
d. Remove the two screws securing the base plate through the A100 board
to the main chassis.
e. Remove the two screws securing the A100 board to the main chassis.
Lift the board up away.
4. Reinstallation: Reverse step 3 to reinstall the A100 board.
