A circuit that samples a through signal, while minimizing attenuation, distortion, or other perturbation to the through signal and sampled signal. The present invention provides for an active distributed signal sampler that includes two transmission lines. An input port is coupled to the first transmission line for receiving the through signal, and a through output port is coupled to an output end of the first transmission line for outputting the through signal. The second transmission line is terminated at one end and has a sampled output port at an output end of the second transmission line for outputting the sampled signal. A plurality of high impedance amplifiers bridge between the transmission lines, and a plurality of inductors are coupled between each of the high impedance amplifiers. A plurality of transmission lines may be optionally employed in the second transmission line.
