Calibration for NA, CAT, and VVM Modes
— If a jumper cable or adapter is required to connect the DUT to the FieldFox,
then connect those components to the FieldFox connectors. The effects of
those components will be measured and removed during the calibration,
and only the effects of the DUT will be displayed in the measurement
results. These should be high-quality components!
— In NA, CAT, or VVM Mode, press Cal 5
.
—Then Mechanical Cal
This page summarizes the Mechanical Cal to be performed and allows you to
make changes. For best results, review the screen and make changes in the
following order:
1. S-parameters – Verify that these are all of the S-parameters that you want
calibrated. If not, press Esc
to terminate the calibration process, then
return to the Trace menu to display all of the traces to be calibrated. Learn
how in “Multi-Trace Configurations” on page 91
2. DUT Connectors – For each DUT port that is shown, verify the correct type
and gender of the DUT connector. If a DUT port is not shown, then that
port is not included in the list of S-parameters to be calibrated.
3. Cal Kit - Verify the correct Cal Kit for each DUT port to be calibrated. See a
list of supported Cal Kits in the FieldFox Data Sheet. Learn more in
Appendix B.
If the DUT connector type, gender, or Cal Kit is NOT correct for the DUT
ports to be calibrated, then:
— Press Change DUT Connectors
to select the correct connector types
that are on your DUT.
— For each port:
— Use the arrows or rotary knob to change the DUT
connector type.
