40 MHz Bandwidth Digitizer Retrofit Kit
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.
