 Press
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:
www.keysight.com/find/fieldfoxsupport.
Follow the Cal Wizard prompts. Connect the specified standard at the point where
the DUT will be connected, then press Measure.

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 Keysight 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
Select an ECal module that has connectors of the same type and gender as the DUT.
If such an ECal module is not available, a module with connectors different from the
DUT can be used by selecting a User Characterization. However, a User
Characterization can NOT be PERFORMED using the FieldFox. It must be performed
using a bench top Keysight VNA, such as the PNA or ENA. Learn more about User
Characterization at the PNA Help website:

NOTE The frequency range of the measurement MUST be within the frequency range of the
ECal module or an error will appear when "Calculating Steps" during the calibration.
 Connect the ECal module USB cable to the FieldFox USB.
 Allow the module to warm up until it indicates READY.
 Connect the ECal module ports to the FieldFox at the calibration reference plane
