Pci-5122 is an oscilloscope device from National Instruments (NI), a flexible software-defined instrument that can be used for time – and frequence-domain measurements and is available in industry standard forms such as PCI and USB.

The PCI-5122 has a software-selectable dynamic range to capture more than 1 million waveforms in on-board memory, making it ideal for time – and frequency-screen analysis. In addition, it has more than 50 built-in measurement and analysis functions, which are programmed directly in the driver software and can be further expanded to 400 in NI LabVIEW and LabWindows/CVI.

In terms of functionality, the PCI-5122 has a software-selectable dynamic range, including input impedance options of 50 ohm and 1 M ohm, and an input range of 200 mVpp to 20 Vpp. Its high resolution of 14 bits guarantees high precision measurement results. In addition, the PCI-5122 includes the NI Spectrum Measurement Kit (32MB and 256MB models only), which provides additional complex power spectrum, peak power and frequency, in-band power, adjacence-frequency power, three-dimensional spectrogram analysis, and more.

In addition, there may be other versions or variants of PCI-5122, such as PCI-5122EX, with specific performance parameters such as a sampling rate of 100 ms/SEC. Therefore, when selecting a specific model, it is necessary to consider it according to the actual application requirements.

Overall, the PCI-5122 is a powerful and versatile oscilloscope device for a variety of applications requiring high-precision time and frequency domain measurements.
