X-Series Adjustments Overview

Adjustments should not be used for calibration. These procedures are designed to reset various circuit parameters. In addition, some of the tests reset or calculate correction values associated with some measurements. The software is designed to adjust an instrument operating within the temperature range defined by the instrument specifications.

Never perform adjustments as routine maintenance. Adjustments should be performed only after a repair or a performance test failure.

A log file for each adjustment will be saved at the following location:

<Agilent TME root folder>\MXA\Output\<Model_Serial>

For example:

C\Program Files\Agilent TME\MXA\Output\N9020A_US01020049

If you have replaced the hard disk drive in your instrument, replacement hard disk drives (HDD) will contain generic calibration data on the Calibration Partition (E:\). The full list of adjustments must be performed on the X-Series analyzer in order to have instrument-specific data on the Calibration Partition.
