The Keysight MXR404A Infiniium Oscilloscope is a 4-channel, 4 GHz bandwidth instrument engineered for signal integrity testing, debugging, and protocol validation. It delivers 10 GSa/s per-channel sampling (40 GSa/s interleaved) with 10-bit ADC resolution and up to 2 Gpts memory depth per channel. The 15.3-inch capacitive touchscreen display supports real-time waveform update rates to 400,000 waveforms/sec with multi-touch gesture navigation.
