Adjustments Overview

  • N7841A calibration application versions E.04.02 and greater require a minimum version of firmware to be installed in the FieldFox to successfully run tests and adjustments. Refer to the Firmware Requirements section for more information.

  • Some FieldFox model and option combinations will require the installation of the CFG Option in order to complete tests. All adjustments will require the CFG Option. Refer to the CFG Option section for more information.

Adjustment procedures determine correction and/or compensation factors for the FieldFox measurement hardware. These factors are required to achieve expected measurement accuracy. The factors from each adjustment are stored in the FieldFox.

Each completed adjustment is assigned a result of Complete or Fail. A failed adjustment indicates one or more of the factors produced by the adjustment was outside an acceptable range. Some adjustments produce a text file that may be useful when troubleshooting.

Adjustments must be performed while the FieldFox internal temperature is within the range specified in the warm-up section.

Most adjustments should not be performed as routine maintenance, and should be performed only after a repair or a test failure. 

If the instrument is unable to successfully complete any of the required adjustments, repairs may be required. 

Adjustments by Model Number
