The Keysight DSOS104A is a 1 GHz digital storage oscilloscope in the Infiniium S-Series, delivering high-resolution signal analysis across four analog channels with upgradable bandwidth to 8 GHz. The instrument achieves 20 GSa/s on two channels or 10 GSa/s across all four channels, paired with 100 Mpts/channel memory (expandable to 800 Mpts). Its 10-bit ADC provides four times the vertical resolution of conventional 8-bit designs, with optional high-resolution mode reaching 16 bits. System ENOB averages 8.1 bits at full bandwidth, while input noise measures 90 µV at 1 mV/div with 1 GHz bandwidth and spurious-free dynamic range of -73 dBc.
