The HP/Agilent 54720A is a modular, real-time digital oscilloscope mainframe that delivers high-performance signal acquisition through a flexible, plug-in architecture. Four acquisition slots accept customizable modules—from single-wide to four-wide configurations—enabling sample rates from 2 GSa/s up to 8 GSa/s and bandwidth up to 1.5 GHz, depending on installed plug-ins. Deep acquisition memory (16K to 256K points) and pre-trigger capability support capture of transient events and single-shot phenomena with 50-ps time interval measurement accuracy.
