  • Full auto-calibration support


The Tech square PXIe-9834 PXI Express digitizer provides high-speed, high-quality data acquisition with four input channels supporting up to 80MS/s sampling and 16-bit data resolution. This allows simultaneous recording of signals on all channels with no interchannel phase delay. The PXIe-9834 features external digital trigger input and triggers from the PXIe system timing slot and reference clock from the PXIe chassis, making it easy to achieve high simultaneous channel count recording of 8, 12, 16, and 20 channels. The PXIe-9834 is also equipped with 1GB of onboard memory for data buffering before transferring back to system memory. The PCI Express x4 Gen1 data bus has enough bandwidth to directly stream ADC data back to the system, if necessary.

The PXIe-9834 features an analog front-end with a flexible input range of ±10V (1MΩ only), ±5V, ±1V, and ±0.5V along with software selectable 50Ω or 1MΩ input impedance. With its sophisticated design and calibration, the analog front-end provides high accuracy, low noise, and high dynamic range performance, making it suitable for accurate DC signal measurement and AC signal analysis.

The PXIe-9834 is perfect for a wide range of applications including radar signal acquisition, fiber optic sensing, and power signal analysis.
