The following trace is an example of an antenna return loss measurement trace using a
FlexCal calibration..
Calculate the threshold value and compare the recorded Lowest Return Loss to the calcu-
lated threshold value.

NOTES:
VSWR is the antenna manufacturer’s specified VSWR.
Use Handheld Software Tools to convert VSWR to Return Loss, or Return Loss
to VSWR.
If the measured return loss is less than the calculated threshold value, the test fails and the
antenna must be replaced.
