Preamplifier Installation Kit
Preamplifier Installation Kit
Introduction
This retrofit kit provides all parts and instructions for retrofitting the 10 MHz to 50 GHz
30 dB Preamplifier Option 110 into the PSA series analyzers.
The Option Driver Board from the kit is required to bias the preamplifier and to control
the switch that switches the preamplifier in and out of the signal path. This board also
contains the flatness compensation data for the preamplifier.
NOTE
1. This option is not compatible with the Option 1DS, 3 GHz preamplifier. Option 1DS
must be uninstalled before installing Option 110. Damage to the instrument may result
if they are both installed.
2. 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 performance tests does not guarantee
the instrument meets all specifications.
3. The instrument end user must determine whether they need a full instrument
calibration following the installation of the kit. If a full calibration is required,
arrangements regarding the level of calibration must be made between the end user and
the calibration provider.
4. This option is licensed for one instrument model/serial number combination. The
license key will only install on the designated instrument.
