The Analogic DBS901 is a 14-bit arbitrary waveform generator module designed for VXI integration into the DBS9900 carrier chassis. It delivers high-speed signal generation with 14-bit resolution at sample rates up to 100 MHz, supporting demanding applications in semiconductor testing, video and digital communications simulation, vibration testing, and R&D. The modular architecture permits two DBS901 units per VXI slot, optimizing chassis utilization and system cost.
