The Keysight EXR404A incorporates a 10-bit ADC with a sample rate of 16 GSa/s available on all channels simultaneously. A high-resolution ADC’s usefulness is dependent on the low-noise front end that supports the additional quantisation levels. The low-noise front end includes custom ICs, like the 130 nm BiCMOS IC that incorporates user-selectable analogue filters and bandwidth upgrades via a software license. This gives you:

• Four times more vertical resolution than 8-bit oscilloscopes
• Up to 16 bits with high-res mode
• As low as 43 µV of noise, 9.0 bits system ENOB with hardware filtering

See More Information with History Mode and Segmented Memory

The Keysight EXR404A Infiniium EXR comes standard with two useful tools that allow you to look forward and backwards in time. With history mode, simply stop the oscilloscope at any time to review up to 1,024 previous trigger events. With segmented memory, you can capture > 100,000 events post-trigger for analysis, with no limit between events. If your design has an elusive event that only seems to happen when you’re not around, these tools arm the oscilloscope to look for it, then let you review what gets captured at your leisure. And with a full HD screen of 1920x1080 pixels, and support for a second, independent external monitor, that data can be organised and displayed however is best for you.
