The Keysight UXR0704A is a 70 GHz real-time oscilloscope built for high-speed signal analysis in advanced research and production environments. Its four full-bandwidth channels deliver 256 GSa/s sampling across all inputs simultaneously, with 10-bit ADC resolution and 100% time-interleaved sampling. The instrument combines noise performance with femtosecond-level jitter measurement floor and up to 2 Gpts per channel of acquisition memory, making it essential for digital design validation, communications systems characterization, and signal integrity analysis.
