The Keysight MSOS804A is a high-performance mixed-signal oscilloscope integrating 8 GHz analog channels with 16 digital logic channels for simultaneous capture and analysis of complex signal behaviors. Built for signal integrity analysis, high-speed digital debugging, and compliance testing, the instrument delivers 10-bit vertical resolution (up to 16 bits in enhanced mode) across dual acquisition architectures. The 15-inch capacitive touchscreen with XGA resolution supports multi-touch gesture control and intuitive setup wizards.
