Introduction
Option 122, 80 MHz Bandwidth Digitizer or Option 140, 40 MHz Bandwidth Digitizer
provides wide IF bandwidth filtering. However, Option 123, Microwave Preselector
Bypass must also be installed in the instrument to enable wide IF bandwidth
functionality.
There are two reasons Option 123 must also be present:
1. The signal path above 3 GHz is bandwidth limited and drifty as a result of the front
end preselector filter. Option 123 Preselector Bypass eliminates these problems.
2. The Option Driver assembly that is part of Option 123 contains memory that is used
to store Option 122 or 140 calibration files. The Option Driver assembly is not
included in this Option 122 or 140 retrofit kit because Option 123 may already be
installed in the E4446A and E4448A. Also, the Option 123 installation must be
handled as a separate installation process.
This retrofit kit installs an alternate 80 MHz or 40 MHz wide bandwidth IF path
consisting of wide band Analog IF and wide band Digital IF assemblies. Also, a wide
bandwidth bandpass filter and lowpass filter replaces the existing bandpass filter in the
lowband (<3 GHz) path.

Wide Bandwidth Retrofit Kit
NOTE 1. The installation of this kit requires that some performance testing be
performed in order to assure the new option is functioning properly.
This installation note includes a list of required 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.
NOTE 3. Requires Option 123 Option Driver assembly. See Introduction for
details.
NOTE This option is licensed for one instrument model number/serial number
combination. The license key will only install on the designated
instrument.

Installation Procedure
Installation Procedure
Preliminary Hardware Verification
With the instrument powered up, press System, More, Show Hardware. Look for the
Option Driver in the list of assemblies.
If the Option Driver is listed, proceed with the installation of Option 122 or 140.
If the Option Driver is not listed, you must install the Option 123, Switchable Microwave
Preselector Bypass retrofit kit before installing this Option 122 or 140 retrofit kit. The
Option Driver assembly that is part of Option 123 is used to store the Option 122/140 cal
factors.
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
Install the Retrofit Kit
Verify Existing Hardware Configuration
1. Locate the A7 Digital IF assembly. It is in the forth card slot from the power supply.
Refer to Figure 3.
Figure 3 A7 Digital IF Assembly Location
2. If the existing A7 Digital IF assembly has large metal casting covers as shown in
Figure 3, this Option 322 or 340 retrofit kit is the wrong kit for your instrument. Stop
the installation.
This Option 322 or 340 retrofit kit is designed for newer instruments that already
contain the 2nd generation A7 Digital IF assembly, and other circuit assemblies
supported by this newer A7 Digital IF assembly. The 2nd generation A7 Digital IF
assembly has no large casting covers.
3. If the existing A7 Digital IF assembly resembles A7 in Figure 4, continue with the
installation.
4. Locate the A31 Wideband Analog IF assembly in the kit. This assembly is the one
with the MCX connectors visible on top of the board.
