The PA72D16180A is a 16-bit digitizer, capable of capturing waveforms at speeds up to 180Msps. An onboard offset voltage source allows capturing offset signals while still using the optimal range for maximum ADC utilization. Two onboard filters allow suppression of out-of-band noise. The 64MWord onboard memory enables capturing very long waveforms, or sequentially capturing multiple signals with minimal intermediate bus communication.
