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. All the settings are stored in permanent memory, so the device can function in standalone mode every time the power is applied.

Main features:
  • Two modes of operation: Differential and Integral
  • Upper and Lower Level Discriminator resolution: 2048 steps
  • Analog amplification factor from 1 to 256
  • TTL pulse output of programmable duration
  • High-voltage supply of up to 1500V
  • External power input of 9 to 36V
  • Size: 56mm diameter by 60mm long (71mm counting the connector length)
