Description
The PXI-5122 is a high-performance digitizer from National Instruments, designed to meet the demands of sophisticated electronic testing and measurement systems. This device is capable of digitizing signals at a rate of 100 MS/s, providing users with high-speed data acquisition capabilities.
For memory, the PXI-5122 offers several options, including 8 MB (778756-01), 32 MB (778756-02), 256 MB (778756-03), and 512 MB (778756-04), allowing users to select the memory size that best fits their application needs. It also boasts a 14-bit ADC resolution, ensuring high precision in data conversion from analog to digital form.
In terms of performance, the PXI-5122 offers a Spurious Free Dynamic Range (SFDR) of 75 dBc and a Signal-to-Noise Ratio (SNR) of 62 dB, indicating its ability to accurately capture and reproduce signals without significant distortion or noise. The device supports an input impedance that is selectable between 50 Ω and 1 MΩ, providing flexibility in connecting various types of signal sources. Moreover, it can accommodate an input range from 200 mVpp to 20 Vpp, catering to a wide array of signal amplitudes.
Featuring seven trigger modes, the PXI-5122 allows users to precisely control the timing of their signal acquisitions, making it suitable for complex measurement tasks. It is compatible with several software platforms, including NI-SCOPE, LabVIEW, and LabWindows/CVI, offering versatile development and analysis options.
The device is equipped with front panel connectors comprising 3 BNC female connectors, 1 9-pin mini-circular DIN, and 2 SMB jacks, providing a variety of interfaces for connecting to different signal sources or measurement setups. To maintain its performance, it requires external calibration at least once
