Analogic DBS901HV Arbitrary Waveform Generator Module

The Analogic DBS901HV is a 14-bit arbitrary waveform generator module engineered for signal generation in VXI-based test systems. It plugs directly into the Analogic DBS9900 VXI C-size dual instrument carrier, supporting up to two DBS901 series modules per carrier for compact, cost-effective multi-function solutions. With 100 MHz sampling rate and 1 MS of segmentable waveform memory, the DBS901HV delivers precise control over complex custom waveforms with branching and looping capabilities.
