Oscilloscopes and Digitizers

PXI Optical-to-Electrical Converter

PXI Oscilloscope

PXI Oscilloscopes are flexible, software‐defined instruments that are versatile enough for both time‐ and frequency‐domain measurements and deliver the benefits of the PXI platform. They feature up to eight channels that can sample at speeds up to 12.5 GS/s with 5 GHz of analog bandwidth. Using the PXI platform, you can synchronize multiple oscilloscopes with other instruments at picosecond‐level accuracy for high‐channel‐count and mixed‐signal applications. These instruments also feature numerous triggering modes, deep onboard memory, and a driver software API that includes data streaming and analysis functions.

PXI IF Digitizer

PXI IF Digitizers offer onboard signal processing (OSP), which enables features such as quadrature digital downconversion (DDC), real digital downconversion, and anti-alias filtering. Models include a high dynamic range front end and a high‐throughput PXI Express interface, which allows them to stream IF data to disk for hours at the full sample rate. You can also choose a PXI IF Digitizer that can convert IF signals to I/Q data, so you can use this model as a stand‐alone IF digitizer or as part of a Vector Signal Analyzer.

PXI FlexRIO Digitizer

PXI FlexRIO Digitizers feature high-performance analog-to-digital converters with lightweight analog front-ends designed to maximize sample rate, bandwidth, and dynamic range. These modules use FPGAs from Xilinx alongside LabVIEW and Vivado programming options for custom algorithm implementation and real-time signal processing. For applications that require high channel counts, PXI FlexRIO Digitizers use the NI-TClk API and the timing and synchronization capabilities of PXI to achieve sub-sample synchronization between multiple modules in a chassis. These modules also feature an auxiliary I/O connector with GPIO for triggering or digital interfacing and the option for high-speed serial communication.

Digitizer Adapter Module for FlexRIO

Digitizer Adapter Modules for FlexRIO can be used with a PXI FPGA Module for FlexRIO or the Controller for FlexRIO to create a high‐performance instrument with customizable firmware. With sampling rates from 40 MS/s to 3 GS/s and up to 32 channels, these modules cover a wide range of requirements for both time- and frequency‐domain applications. Digitizer adapter modules also provide digital I/O capability for interfacing with external hardware.

C Series Digitizer Module

The C Series Digitizer Module takes both high-speed and high-resolution time- and frequency-domain measurements. It features up to four channels that can sample at speeds up to 20 MS/s—ideal for discrete detection of signals 10 MHz and smaller for applications such as fault detection, partial discharge analysis, and acoustic measurements. The module's store-and-forward architecture allows up to 128 Mbits of measurement data to be sent back to the CompactRIO Controller and analyzed. You can use the module as part of a CompactRIO system and use the LabVIEW FPGA Module to develop an advanced trigger based on low-speed streaming for added flexibility. This digitizer includes the NI-DAQmx driver and configuration utility that simplifies configuration and measurements. NI-DAQmx supports NI programming environments and Python, ANSI C, C#.NET, and MathWorks MATLAB® software.

Oscilloscope Device

Oscilloscope Devices are flexible, software‐defined instruments that are versatile enough for both time‐ and frequency‐domain measurements and are offered in industry-standard form factors like PCI and USB. They feature up to eight channels that can sample at speeds up to 2 GS/s. The devices also feature numerous triggering modes, deep onboard memory, and driver software API that includes data streaming and analysis functions.

FlexRIO Digitizer Device

FlexRIO Digitizer Devices feature high-performance analog-to-digital converters with lightweight analog front-ends designed to maximize sample rate, bandwidth, and dynamic range. These devices use FPGAs from Xilinx alongside LabVIEW and Vivado programming options for custom algorithm implementation and real-time signal processing. These devices also feature an auxiliary I/O connector with GPIO for triggering or digital interfacing and the option for high-speed serial communication.

Oscilloscope Probe

Oscilloscope Probes can conduct signals up to 2.5 GHz, 300 V, or 500 Arms, even in extreme environments. They offer fixed attenuation of 10X or 100X or switchable attenuation between 1X and 10X. Oscilloscope Probes are offered in several types, including single-ended and differential, active and passive, voltage and current.
