Keysight EXR258A Mixed Signal Oscilloscope

Overview

The Keysight Infiniium EXR258A is a 2.5 GHz 8-channel mixed signal oscilloscope offering maximum channel capacity for comprehensive multi-signal analysis. With a 10-bit ADC providing simultaneous 16 GSa/s sampling on all channels, 100 Mpts per channel memory, and 500 GB SSD storage, the EXR258A represents the pinnacle of the EXR-Series performance.

Like the broader EXR-Series, it integrates seven instruments in one—oscilloscope, logic analyzer, arbitrary waveform generator, frequency response analyzer, counter, voltmeter, and protocol analyzer. Its fully upgradeable architecture enables users to expand bandwidth and capabilities through software licenses, protecting instrument investments long-term.
