Claim:
1. A configurable bias tee network having an AC signal port, a triaxial DC signal port having a guard, and a triaxial AC+DC signal port having a guard, comprising: a first electrical network coupled between the DC signal port and the AC+DC signal port, the first electrical network providing a DC path between the DC signal port and the AC+DC signal port; and a second electrical network coupled between the AC signal port and the AC+DC signal port, the second electrical network including a first capacitor, a first switch, and a second capacitor connected in series, and the second electrical network providing an AC path between the AC signal port and the AC+DC signal port when the first switch is closed, and disconnecting the AC path when the first switch is opened; in which the guard of the DC signal port is connected to the guard of the AC+DC signal port, and in which the first capacitor and the first switch are series coupled between the guards and the AC+DC signal port.
