54853A

Keysight Technologies (Agilent HP)Digital

The Keysight Technologies (formerly Agilent) Infiniium 54853A is a high-performance 4-channel digital real-time oscilloscope. Delivering a 2.5 GHz analog bandwidth and a maximum sampling rate of 20 GSa/s on all channels simultaneously, it is engineered for characterization and debugging of high-speed digital designs. Its MegaZoom deep memory architecture and compatibility with the InfiniiMax active probing system make it a reliable choice for demanding physical-layer testing.
