Attenuation Error (AttErr) definition
AttErr(i) = Measured_dB(S21)state(i) –Measured_dB(S21)state(0) -
theoreticalAttenValueState(i)
(i) is in the range [0:63]
AttErr(i) is in dB and AttErrLin(i) is the corresponding linear value :
AttErr(i) = dB(AttErrLin(i))
Phase Variation (PhiVar) definition
PhiVar(i) = measured_Phase(S21)@state(i) – measured_Phase(S21)@state(0)
(i) is in the range [0:63]
