NI oscilloscopes and digitizers are precision modular instruments for capturing and analyzing electrical signals in automated test and high-channel-count systems. Oscilloscopes provide interactive, real-time visualization and measurement, ideal for debugging and design validation, while digitizers deliver high-speed, deep-memory data acquisition for advanced analysis and long-duration recording through software control with fully user-programmable FPGA.
An NI Partner is a business entity independent from NI and has no agency or joint-venture relationship and does not form part of any business associations with NI.
PXI and PCI general-purpose oscilloscopes offer scalable multichannel data capture in a compact, highdensity modular design, well suited for automated test systems with space and channel needs. General-purpose PXI/PCI oscilloscopes deliver scalable multichannel acquisition in a high-density and compact modular format, ideal for automated test systems with demanding space and channel count demands.

Features
NI PXI Oscilloscopes are flexible, modular, software‐defined instruments designed for both time‐ and frequency‐domain measurements. They feature advanced triggering modes, deep onboard memory, and a driver software API with data streaming and signal analysis functions.
NI oscilloscopes offer an integrated interface with built-in controls, visualization, analysis, and workflows, while digitizers emphasize programmatic control, streaming, and integration with automated tests.
Oscilloscopes measure and display signal voltage over time, enabling engineers to observe waveform behavior, verify signal integrity, analyze timing relationships, and troubleshoot electrical issues. They are essential tools for validating the performance of electronic components, detecting anomalies such as noise or distortion, and ensuring compliance with design specifications.
Digitizers and oscilloscopes both convert analog signals to digital data, but their roles and features differ: Digitizers focus on high-speed, high-resolution data acquisition, often with deeper memory and software integration for automated test systems. Digitizers are ideal for capturing long-duration signals and processing data offline or in custom software environments such as LabVIEW.
Modern software-defined oscilloscopes and digitizers can be evaluated across many parameters, including bandwidth, sampling rate, sampling modes, resolution and dynamic range, triggering, onboard memory, channel density, multiple instrument synchronization abilities, mixed signal capability, software, analysis options, and customizability. Understanding what will be tested and measured is critical to finding the right oscilloscope or digitizer.
NI PXI-based oscilloscopes and digitizers are modular instruments, making it easy to add them to existing test system architectures for applications requiring a high-channel count. Fast data transfer speeds, tight synchronization, integration with NI software such as LabVIEW, and robust support and technical resources are advantages of including NI oscilloscopes and digitizers within automated test systems.
