Agilent / Keysight DSOX4104A Oscilloscope: 1 GHz, 4 Analog Channels

The Agilent/Keysight DSOX4104A is a 1 GHz, 4-channel analog oscilloscope built for signal analysis, troubleshooting, and embedded system validation. This benchtop instrument delivers 5 GSa/s sampling across all channels with 4 Mpts memory depth, enabling capture and detailed inspection of complex transients and multi-burst events. The 12.1-inch capacitive touchscreen provides intuitive navigation and clear waveform visualization, while Zone Touch triggering lets engineers quickly isolate signals of interest by drawing a box directly on screen.
