Digitizers/Oscilloscopes

Digitizers offer unmatched versatility for both time and frequency domain applications due to an open architecture and functionality driven by flexible software. With a National Instruments digitizer, you can not only perform standard oscilloscope measurements but also easily build other instruments, such as spectrum analyzers, transient recorders, and ultrasonic receivers. In addition, you can synchronize multiple NI digitizers and other mixed-signal instruments with picosecond-level accuracy for high-channel-count and mixed-signal applications.

High Speed

NI high-speed digitizers, with up to 1 GHz bandwidth and 2 GS/s sample rates, are optimized for automated test by combining strong instrument integration with faster test times resulting from the high-throughput PXI bus. These digitizers are ideal for automated test applications in the consumer electronics, semiconductor, aerospace/defense, and life sciences industries.

High Resolution

NI high-resolution digitizers use the latest commercial semiconductors to make high-dynamic-range, low-distortion measurements with wide bandwidth. These digitizers include the award-winning NI PXI-5922 flexible-resolution digitizer, which can achieve up to 24 bits of vertical resolution.

High Channel Count

High-channel-count digitizers include four or more analog input channels, up to 60 MS/s sample rates, and up to 24-bit resolution. These digitizers are ideal for applications requiring both high resolution and extremely high channel counts, such as ultrasonic nondestructive test (NDT).

Low Cost

NI low-cost digitizers make extensive use of commercial technology to optimize performance for cost-sensitive applications. Low-cost digitizers include the 8-channel, 60 MS/s digitizer – which has the lowest price per channel in its class – as well as portable, bus-powered USB digitizers.

Accessories and Software

NI offers probes, cables, and software to provide the connectivity and expanded capability required of your digitizer for your application.
