The bPAD is an intelligent, compact Single-Channel Analyzer. Unlike traditional designs, this device is fully digitally controlled via USB: no scope or messing with screwdrivers is necessary. A simple PC application allows all the parameters (High Voltage level, amplification factor, discriminator thresholds) to be quickly set. More than that, a pseudo PHA mode is implemented, allowing to acquire an spectrum in order to set the discriminator window from the peak of interest.
