Description
The PXI-5122 is a high-performance digitizer featuring a digitizer speed of 100 MS/s. This device comes with several memory options to cater to various application needs, including 8 MB (778756-01), 32 MB (778756-02), 256 MB (778756-03), and 512 MB (778756-04). It utilizes 14-bit Analog-to-Digital Converters (ADCs) to ensure high-fidelity data conversion, achieving a Spurious Free Dynamic Range of 75 dBc and a Signal-to-Noise Ratio of 62 dB.
The input impedance is software selectable between 50 Ω or 1 MΩ, providing flexibility for various signal types. The device supports an input range from 200 mVpp to 20 Vpp, accommodating a wide range of signal amplitudes. It offers seven trigger modes, enabling users to precisely control the timing of their measurements. The front panel includes three BNC female connectors, a 9-pin mini-circular DIN, and two SMB jacks, offering versatile connectivity options.
Designed to operate within a temperature range of 0 to 55 °C, the PXI-5122 ensures reliable performance in various environments. It features self-calibration, with an external calibration recommended every two years to maintain accuracy. The device is compatible with NI-SCOPE driver, LabVIEW, and LabWindows/CVI software, ensuring easy integration into existing systems. A recommended warm-up time of 15 minutes is suggested for optimal performance.
For calibration, users have the option of NIST accredited calibrations through a third party or basic in-house calibration, providing flexibility in maintaining measurement accuracy. The maintenance phase for the PXI-5122 began on December 30, 2022
