NOTE
Simple Response Cals
Simple Response Cals are used to quickly calibrate the magnitude and phase of a
measurement using any Open, Short, or Thru component. These may be calibration
standards, but because a Cal Kit is not selected, they are not modeled. Measurement
accuracy is generally low. Use a Simple Response Cal to make quick measurements
when using a jumper cable to connect the DUT to the FieldFox. Otherwise, CalReady
is usually more accurate.
NOTE You can perform a Simple Response Cal for either: S11, S22, or S21 AND S12.
When prompted, choose a standard based on the displayed measurements to be
calibrated. For example, to calibrate S11, connect either an OPEN or SHORT
standard to the port 1 reference plane.
1-port response cals are also available from the Mechanical Cal menu. Learn more
on page 72.

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 ECal
ON
o
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 be
ON
o
connected at both calibration reference planes. You therefore receive a single
prompt to connect the ECal module to both ports.
Select when physical restrictions prohibit the ECal module from being
OFF
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.

Measure. The standards within the ECal module are automatically connected and
measured.
When prompted: "Connect port 1 to port 2", then you can connect them however you choose,
including using the internal ECal THRU. This is an 'Unknown THRU'.
When prompted: "Connect port 1 directly to port 2", then you must connect the ports directly
together at the calibration reference plane with no adapter or other cabling. This is a 'Flush
THRU'.
