Option 426 Gated Sweep Hardware Retrofit Kit
Option 426 Gated Sweep Hardware Retrofit Kit
Introduction
This retrofit kit provides all the parts and instructions for installing Gated Sweep (Time
Gating) in instruments shipped prior to the introduction of gated sweep. The A12A1 LO
Synthesizer assembly, the A13 Front End Driver Retrofit Kit, and firmware need to be
installed to upgrade the instrument for gated sweep.
This installation note covers both the E4446A/E4448A version and the
E4440A/E4443A/E4445A version of the retrofit kits. The Gated Sweep Retrofit kits
contain different Front End Driver Retrofit kits. Otherwise they are the same.
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.
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.
