Definitions

n: Attenuator state index with 0

≤ n ≤ 63

Phase_S21(n):

Measured phase of S21 in degree at attenuation state n

dB_S21(n):

Measured magnitude of S21 in dB at attenuation stateni

Attenuation Error (Att_err)

Att_err(n)= dB_S21 (n) - dB_S21(0)

The translation of Att_err(i) from dB to linear is given by: Att_err_lin(n) =
