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.

Signal integrity characterization, transient capture, EMI/EMC pre-compliance analysis, prototype validation, and manufacturing test environments requiring simultaneous multi-channel observation with sub-picosecond timing precision.
– Compatibility & Integration
Designed for InfiniiMax probing system compatibility, supporting browse, solder-in, and socket probe configurations with bandwidths from 5.5 GHz (single-ended browser) to 7 GHz (differential variants). The E2697A High Impedance Adapter extends measurement capability to power supplies and inverters with switchable AC/DC coupling and 10:1/1:1 attenuation. USB rear-panel port enables data file, setup, and screenshot transfer. Standard LAN interface supports PC-based connectivity and data sharing.
