The Keysight UXR0252AP is a high-performance real-time oscilloscope delivering 25 GHz bandwidth with 10-bit analog-to-digital conversion for precision signal acquisition across demanding test environments. Built on a modular architecture, this instrument captures complex waveforms at 256 GSa/s across 2 full-bandwidth channels with up to 2 Gpts memory per channel. The platform supports channel expansion to 4 inputs and bandwidth scaling to 110 GHz, protecting long-term investment in R&D infrastructure. Ultra-low intrinsic jitter of 25 fs rms and noise floors as low as 210 µVrms at 10 mV/division enable signal fidelity critical for high-speed digital design, RF communications, and aerospace applications.
