Description
The PXI-5122 is a high-performance digitizer that features a variety of specifications tailored for advanced signal acquisition and analysis. This model comes with different part numbers based on memory options, including 8 MB (778756-01), 32 MB (778756-02), 256 MB (778756-03), and 512 MB (778756-04), providing flexibility in memory capacity to suit various application needs.
It boasts a sampling rate of 100 MS/s (Mega Samples per second), ensuring precise capture of high-frequency signals. The digitizer’s resolution is powered by 14-bit ADCs (Analog-to-Digital Converters), enabling it to deliver detailed and accurate measurements of the signal’s amplitude.
The Spurious Free Dynamic Range (SFDR) is specified at 75 dBc, which indicates the digitizer’s ability to accurately measure signal amplitude in the presence of strong, spurious signals. Additionally, it has a Signal-to-Noise Ratio (SNR) of 62 dB, ensuring that the signal integrity is maintained by minimizing the background noise.
One of the key features of the PXI-5122 is its input impedance, which is software selectable between 50 Ω or 1 MΩ. This allows users to optimize the digitizer for different types of signals. The input range of 200 mVpp to 20 Vpp offers a broad spectrum for signal amplitude, catering to a wide variety of measurement needs.
The device supports seven trigger modes, enhancing its flexibility in capturing signal events. It is also equipped with anti-alias and noise filters, which are crucial for maintaining signal fidelity by reducing unwanted frequencies and noise.
Regarding software compatibility, the PXI-5122 works seamlessly with NI-SCOPE driver software, LabVIEW, and LabWindows/CVI, providing a versatile development environment for users. The connectors include 3 BNC female, a 9-pin mini-c
