NI Delivers High-Resolution, High-Speed Digitizer

8/15/2002 - National Instruments extends its product line to include a wide-band, high-resolution digitizer for time and frequency domain measurements on the industry-standard PXI/CompactPCI measurement platform.

The new NI PXI-5621 is a 14-bit, 64 MS/s, 64 MB high-speed digitizer that delivers outstanding distortion performance and dynamic range. With a bandwidth of DC to 36 MHz, the digitizer is ideal for many applications, including spectral analysis, ultrasound and radar testing, high-resolution ATE, and video/imaging applications. The NI PXI-5621 digitizer features:

The NI PXI-5621 digitizer comes with NI-SCOPE driver software that includes 50 built-in measurement and analysis functions. It also includes spectral measurements software with built-in functions for zoom FFT processing based on center frequency, span, and resolution bandwidth (RBW) parameters. The software works with different types of frequency domain averaging such as RMS, vector, and peak-hold. It contains functions for frequency domain measurements such as peak power and frequency, power spectral density, as well as measurements for digital communications, including power-in-band, adjacent-channel power, and occupied bandwidth. The software includes examples for common applications.

NI-SCOPE and the spectral measurements software seamlessly integrate with LabVIEW, LabWindows/CVI, Visual Basic, and Visual C/C++.
