Switchable Microwave Preselector Bypass
Installation Kit
Introduction
This installation note explains how to install the Switchable Microwave Preselector
Bypass into newer instruments that have the serial prefix listed above.
Because the mixer in this kit requires the same FELOMA LO output that the external
mixing option AYZ requires, the two options cannot be installed at the same time.
The retrofit adds a switchable alternate signal path when the analyzer start frequency is
above 3.05 GHz. This alternate path bypasses the preselector filter and mixer in the
normal highband path. The advantage of bypassing the preselector is that the
preselector filter will drift with time and temperature and will cause small amplitude
errors.
When the preselector is bypassed, images, multiples and out of band responses will
appear on the analyzer display since there is no longer a bandpass filter present to limit
the input frequency range of the analyzer. Therefore, the display may show many signal
responses even though only one response is the true signal. Since the preselector can be
switched in or out easily, it is possible to find a signal in preselected mode and tune to it,
then switch the preselector out and measure it.

NOTE
1. The installation of this kit requires that some re-adjustment and performance testing
be performed in order to assure the new option is functioning properly. This installation
note includes a list of required adjustments and performance tests. Completing the list
of required performance tests does not guarantee the instrument meets all
specifications.
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.
3. This option is licensed for one instrument model number/serial number combination.
The license key will only install on the designated instrument.

Before you begin the kit installation:
The instrument should be fully functional and pass all of the power on align tests. If an
alignment test fails, either note the failure and go on with the kit installation or repair
the problem now. Since the following installation involves removing and replacing cables
and removing and reinstalling major assemblies, you must be aware of the instrument
status before you begin the kit installation.
