The HP/Agilent 54645D is a 100 MHz, 200 MSa/s mixed-signal oscilloscope combining 2 analog and 16 digital channels for simultaneous capture and analysis of complex embedded and mixed-signal designs. The instrument delivers 8-bit vertical resolution across both analog and digital domains, supported by deep memory—50,000 points per analog channel and 25,000 points per digital channel—enabling extended waveform capture at full sample rate.
