4 diode beam lead Schottky diodes on a 5 mil duroid replaceable carrier, coupled to a beam lead [[Step_recovery_diode|SRD]] based driver also on 5 mil duroid substrate with pins to plug into sockets in the housing. This is all on the side of the lid. The other side of the housing has a polyimide flexible circuit connecting to the [[LEMO_S-series_connector|4 pin LEMO connector]]. | 4 diode beam lead Schottky diodes on a 5 mil duroid replaceable carrier, coupled to a beam lead [[Step_recovery_diode|SRD]] based driver also on 5 mil duroid substrate with pins to plug into sockets in the housing.

The two extra wire provide the sampler bias and send back the average value of the sampled signal. | ||
