Overview
The JY-9817/9815/9813 PXI Express digitizer provides high speed, high quality data acquisition. Each of 4 input channels supports up to 125 MS/s sampling, with up to 16-bit resolution. This allows simultaneous recording of signals on all channels with no inter-channel phase delay. The extremely large onboard memory enables long recording times even at the highest sampling rates.
The PCIe/PXIe-9817 features flexible input ranges of ±0.5 V,±1 V, ±5 V, and ±10 V along with software selectable 50 Ω or 1 MΩ input impedance. Four high resolution 16-bit A/D converters combine with a low-noise/high bandwidth analog front-end to make the PXIe-9817 perfect for applications like radar signal acquisition, fiber optic sensing, and many others.
