{{Note|For Network Analysis Test, all the AC voltage sources must be short-circuited and all the AC current sources must be open-circuited.}}
A tracking crosshair has been used to read the value of |s21| at 1GHz. This value is 8.02dB. Note that the total input reflection coefficient and the total output
reflection coefficient are both below -10dB at 1GHz and the overall |s12| of the circuit is negligible.
