Digital Demodulation Hardware Retrofit Kit
Digital Demodulation Hardware Retrofit Kit
Introduction
This kit is required to retrofit the digital demodulation hardware on early Agilent
E4440A spectrum analyzers with serial prefixes less than or equal to those shown above.
The kit contains the latest third converter and reference assembly in addition to the
Option B7J electronic attenuator and cables. Instruments with serial prefix greater than
4042 do not require the third converter and reference assembly, so these instruments
can be upgraded with the Option B7J kit. The option is licensed to one instrument model
number/serial number combination. The kit will function only in the instrument for
which it was ordered.
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.
