Agilent/Keysight 54831M

The Agilent/Keysight 54831M is a 600 MHz, 4-channel mixed-signal oscilloscope (MSO) from the Infiniium Series, engineered for advanced debugging and analysis of complex electronic designs. This military-specification variant integrates 16 digital channels alongside four analog channels, delivering mixed-signal triggering and simultaneous acquisition across both analog and digital signal domains. The 54831M shares identical electrical specifications with the 54831B, with differences limited to military-specific accessories and documentation.
