Definitions
Phase(i,j) =Phase_S21 in degree
i: Phase state index, 0
≤ i ≤ 63
dB_S21(i,j) =dB_S21 in dB
j: Fine attenuation state index, 0
≤ j ≤ 63
Peak Phase Error (PPE)
PPE(i,j) = Measured_Phase(S21)@state(i,j) - Measured_Phase(S21)@state(0,j) -
theoreticalPhaseValue@State(i,j)
Amplitude Variation (Ampvar)
Ampvar(i,j) = Measured_dB_S21@state(i,j) - Measured_dB_S21@state(0,j)
(i) is the phase state and in the range [0:63]
The translation of Ampvar(i,j) from dB to linear is given by: Ampvar(i,j)_lin =
