Calibration Type
- The FieldFox always RECOMMENDS a Cal Type that will
quickly and accurately calibrate all of the displayed S-parameters. Change
from the RECOMMENDED Cal Type ONLY if you understand the
implications. Learn more about Cal Types on page 73.

NOTE
If an error appears (“
Failure to compute calibration steps
…”), check to ensure
that the frequency range of the Cal Kit covers the frequency range of the
measurement. You can verify the frequency range of your Cal Kit at:

Follow the Cal Wizard prompts. Connect the specified standard at the point
where the DUT will be connected, then press

ECal
ECal is a complete solid-state calibration solution. Every ECal module contains
electronic standards that are automatically switched into position during a
calibration. These electronic standards have been measured at the factory and
the data stored within the memory of the ECal module. The FieldFox uses this
stored data, along with the measured data, to calculate the error terms for a
measurement calibration.
You can perform the following calibrations with ECal:
1-Port Reflection calibration
Full 2-Port calibration
All Agilent USB ECal modules are supported. ECal modules are available in a
variety of connector types, covering many frequency ranges. For information
about available ECal modules, see
