Agilent / Keysight DSOS404A High-Definition Oscilloscope: 4 GHz, 4 Analog Channels

The Keysight DSOS404A is a 4 GHz, 4-channel high-definition digital oscilloscope built for precision signal analysis in demanding measurement environments. This Infiniium S-Series instrument delivers 10-bit ADC performance with up to 16 bits of vertical resolution using advanced system architecture and high-resolution mode. Sample at 20 GSa/s across 2 channels or 10 GSa/s across all 4 channels, with standard memory of 100 Mpts/channel (expandable to 800 Mpts). The system achieves an average ENOB of 8.1 bits at full bandwidth, ensuring signal fidelity for subtle waveform detail capture. Its 15-inch XGA capacitive touch screen supports multi-touch gestures, intuitive menu navigation, and flexible waveform viewing—up to 16 separate graticule areas or unified display. Windows 10 OS with 256 GB removable SSD enables fast boot and portable data management. Over 50 automated measurements with simultaneous statistics display, 16 math functions, and advanced triggering support complex signal characterization. Hardware supports vertical scaling as low as 2 mV/div. Optional protocol, compliance, and analysis software extends capabilities for power supply and signal analysis workflows. Second monitor output allows interface customization for multi-operator or production environments.
