Keysight (Agilent) MXR408A Infiniium Oscilloscope, 4 GHz, 8 Channels

The Keysight MXR408A Infiniium Oscilloscope is an 8-channel, 4 GHz real-time oscilloscope engineered for complex signal analysis and high-speed digital characterization. Built on hardware acceleration ASICs derived from the Infiniium UXR-Series, it delivers waveform update rates exceeding 200,000 wfm/s with exceptional signal integrity. The instrument combines deep acquisition memory, flexible three-stage triggering, and an 8-in-1 integrated measurement platform - oscilloscope, logic analyzer, protocol analyzer, DVM, counter, real-time spectrum analyzer, Bode plotter, and waveform generator.

Full bandwidth and channel upgradability protects long-term measurement investments.
