What Are PXI Oscilloscopes?

PXI Oscilloscopes are flexible, software‐defined instruments that are versatile enough for both time‐ and frequency‐domain measurements and feature numerous triggering modes, deep onboard memory, and a driver software API that includes data streaming and analysis functions.

Synchronized Instruments

PXI Oscilloscopes of the same model are automatically hardware synchronized across multiple devices in InstrumentStudio software to serve applications requiring high channel density. Using hardware-timed triggers over the PXI backplane, they can also handshake with other types of instruments in the chassis.

CableSense™ Technology

Using principles similar to a traditional time-domain reflectometer (TDR) on a real-time oscilloscope within your test system, you can detect changes from a known, golden setup without having to alter the connections themselves.

InstrumentStudio™ Interactive Software

PXI Oscilloscopes are shipped with an interactive, multi-instrument soft front panel called InstrumentStudio for ready-to-run configuration and measurements. You can also monitor and debug the instrument in parallel with running code.

Deep Onboard Memory

PXI Oscilloscopes feature deep onboard memory, capable of storing multiple acquisitions from single channels or parallel acquisitions from multiple channels on the same device, and also benefit from the high-speed streaming capabilities of the PXI platform.
