Agilent/Keysight DSOS404A

The Keysight DSOS404A is a 4 GHz digital oscilloscope built on the Infiniium S-Series platform for high-fidelity signal analysis and complex waveform characterization. With four analog channels, 20 GSa/s sampling (on 2 channels), and a 10-bit ADC expandable to 16-bit resolution in High Resolution Mode, this instrument delivers 8.1 bits average ENOB at full bandwidth with intrinsic jitter of 100 fs typical. The 15-inch XGA capacitive touchscreen, Intel i5 processor, and 100 Mpts standard memory (upgradable to 800 Mpts on 2 channels or 400 Mpts on 4 channels) enable rapid data acquisition and analysis. Over 50 automated measurements, 16 math functions, advanced triggering modes, serial bus decoding, and spectral analysis with gated FFTs address signal integrity validation across RF, digital, and mixed-signal designs. Optional 16-channel MSO capability accommodates state and pattern triggering for protocol and timing analysis. Vertical sensitivity ranges to 2 mV/division. Multiple interfaces—USB 3.0, Ethernet 10/100/1000, GPIB, DisplayPort, and VGA—support remote control and data transfer. The unit runs on 100–240 VAC at 50/60 Hz with maximum 380 W consumption and ships with four 500 MHz passive probes, calibration cable, and documentation.
