Agilent/Keysight UXR0204A

The Keysight UXR0204A is a real-time oscilloscope delivering 20 GHz bandwidth across four full-bandwidth channels with 128 GSa/s sample rate and 10-bit ADC resolution. Built on the Infiniium UXR-Series platform, this instrument captures up to 2 Gpts of memory for extended signal observation and maintains intrinsic jitter below 25 fs (rms) with inter-channel jitter under 10 fs (rms). The scope upgrades to 110 GHz bandwidth, supporting future measurement requirements without hardware replacement.
