3 Standards limitations.
5 Accuracy in VSWR column must be calculated and converted to return loss in dB for frequencies above 1 GHz, using
appendix B. New VSWR values must be rounded to nearest value listed in appendix B without tightening the tolerance.
6 Formula, return loss dB = -20 log [(VSWR -1 + (VSWR +1)], can be used to calculate values different from those listed in
7 If out-of-tolerance indication is obtained, provide calibration report of actual values with TI.
