Agilent/Keysight EXR408A

The Keysight EXR408A is a real-time oscilloscope built for complex signal characterization in R&D and manufacturing environments. With 8 analog channels, 16 digital channels, 4 GHz bandwidth (upgradeable to 6 GHz), and 16 GSa/s sample rate across all analog channels simultaneously, it delivers the speed and capacity needed for advanced electronic design validation. The instrument combines extensive memory depth up to 1.6 Gpts, 10-bit ADC resolution (upgradeable to 16-bit), and a low-noise front end at 43 µV with waveform update rates exceeding 200,000 wfm/s for real-time anomaly detection.
