2 PDV Needs and Challenges Cost DigiLzer costs are prohibilve for high channel count applicalons Density ApplicaLons are demanding greater than 10 channels Data Analysis Data analysis Lme reduclon needed to provide very fast measurement results SoSware SoSware needs refinement, standardizalon, and ease of use

3 NI and HEI Addressing Needs and Cost Challenges NI is increasing the value of instrumentalon by developing digilzer sampling rates greater than 10 GS/s Density NI technology reduces footprint and power consumplon Data Analysis Leveraging FPGA technology for inline data processing SoSware HEI is enabling exislng PDV users to focus on their applicalon and expose PDV to a broader audience
