AB  - IRA recently launched a project to digitize all the data acquisition systems it 
      uses for primary radionuclide standardizations. It is well-known that the digital 
      approach presents numerous advantages over the traditional analog electronics 
      such as information losslessness, scalability, online and/or offline data 
      processing, and it is also a solution to the growing difficulties to repair or 
      renew ageing modules. As a first step in this wider program, our institute set-up 
      a 4pibeta-4pigamma digital coincidence counting system, with FPGA (Field Programmable Gate 
      Array)-based commercial boards from National Instruments (NI), to perform data 
      acquisition and offline data analysis. Choosing all components and software from 
      the same supplier provides a full compact and consistent electronic system. To 
      demonstrate and validate the capacity of this system to standardize the activity 
      of radioisotopes, we compare its predictions for the activity concentration of 
      (133)Ba, (166m)Ho and (18)F solutions with the results from a coincidence 
      counting system with analog electronics, as well as with the results from other 
      primary methods and a secondary measurement performed with an IG11 ionization 
      chamber (CIR, chambre d'ionization de reference) with an equivalent activity 
      traceable to the Systeme International de Reference.
