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 Agilent VNA, such as the PNA or ENA. Learn more
about User Characterization at the PNA Help website:

How to Perform a Calibration Using ECal

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

Mechanical Cal / ECal
Change DUT Connectors. For each test port to be calibrated, select the
Connector Type and Gender of the DUT / ECal module. The connected ECal
module and relevant User Characterizations will appear as the default Cal Kit.
Advanced
(default) The FieldFox automatically senses the direction in which the
ON
o
ECal module ports are connected to the FieldFox ports.
If power to the ECal module is too low, it cannot detect which FieldFox
OFF
o
ports it is connected to. If you are having this problem, select OFF. Then
during the calibration, the FieldFox will prompt you to connect the ECal
module ports to specific FieldFox ports.
Advanced
(default) The FieldFox assumes that both ports of the ECal module can
ON
o
be connected at both calibration reference planes. You therefore receive a
single prompt to connect the ECal module to both ports.
OFF Select when physical restrictions prohibit the ECal module from being
o
connected to both calibration reference planes simultaneously. You will
receive separate prompts to connect the ECal module to Port 1, then to
connect the ECal to Port 2.
Start Calibration. When prompted, connect the ECal module, then press
Measure. The standards within the ECal module are automatically connected
and measured.
