Agilent/Keysight 54853A

The Agilent/Keysight 54853A is a 2.5 GHz real-time oscilloscope built on the Infiniium platform for signal integrity analysis in development and manufacturing. This four-channel instrument delivers 20 GSa/s simultaneous sampling with deep memory architecture - up to 1 Mpts at full rate and 32 Mpts at lower sample rates - enabling capture and analysis of complex transient and repetitive signals without performance loss.
