The Model GAO2902/2904/25216A Digital Storage Oscilloscopes DSO/Logic Analyzer integrates two (or four) 250 MSa/s single-shot digitizers with a 250 MHz, 8 (or 16) channel logic analyzer and FFT Spectrum in a single low-cost instruments. DSO slashes the cost of capturing and analyzing signals on up to 50 MHz microprocessors, logic families, and analog circuits on systems.
