原廠英文說明
The National Instruments PCI-5122 / PXI-5122 high-resolution digitizer is suited for a wide variety of applications in automotive, communications, scientific research, military/aerospace, and consumer electronics. With the large dynamic range, software-selectable 50 Ω or 1 MΩ input, ranges from 200 mV to 20 V (up to 100 V with TEGAM signal conditioning amplifier), and ability to acquire more than 1 million waveforms in onboard memory, the PXI-5122 is ideal for both time- and frequency-domain analysis. You can program more than 50 built-in measurement and analysis functions directly from the driver and expand them to more than 400 with NI LabVIEW and LabWindows™/CVI software. The PXI-5122 (32, 256, and 512 MB models only) includes the NI Spectral Measurements Toolkit, which provides additional sophisticated frequency-domain measurements such as power spectrum, peak power and frequency, in-band power, adjacent-channel power, and 3D spectrogram.
