Agilent/Keysight MSOX4034A

The Agilent/Keysight MSOX4034A is a 350 MHz mixed-signal oscilloscope that combines a 4-channel analog front end with 16 integrated digital channels for comprehensive signal analysis. Built around a 12.1-inch capacitive touch display, the instrument delivers up to 5 GSa/s sampling (on half channels) and 4 Mpts of memory to capture transient events with precision. This benchtop platform integrates oscilloscope, logic analyzer, and protocol analyzer functionality in a single 6.3 kg unit.
