Introduction
This installation note explains how to install the hardware, and provides guidelines for adjustment
and verification for Option MPB, Microwave Preselector Bypass, and Option LNP, Low Noise Path.
Please note that the Option HL1 kit designator is only an ordering number.
Option MPB provides mechanical switches and associated hardware that bypass the A12 YTF (YIG
Tuned Filter). The YTF limits the bandwidth of the input signal and also this filter can drift causing
slight amplitude errors.
Option LNP provides a mechanical switch and associated hardware to bypass the A11 Low Band
Assembly when the instrument is tuned to frequencies above 3.6 GHz (High Band path). The A11
Low Band assembly contributes loss to the input signal path and reducing this loss improves the
Display Average Noise Level of the instrument. SHI performance increases also.
Installation Note N9030-90083
The instrument must be readjusted and the performance tested to assure the instrument meets
specifications following the hardware installation. The X- Series Performance Verification and
Adjustment Software must be used. All adjustments are automated. This software is included in
the N7814A performance test & adjustment software package revision E.16.00 or greater.
The option is licensed for one instrument model number/serial number combination. The license
file that is downloaded from the web will only install on the designated instrument.
