Advantech PCIE-1843/PCIE-1843L Analog Input PCIe Cards

Introduction

The Advantech PCIE-1843 and PCIE-1843L are high-speed PCI Express data acquisition cards designed for capturing analog signals in demanding measurement and test environments. With simultaneous analog input channels, 14-bit resolution, and sampling speeds up to 20 MS/s, these cards support accurate acquisition of rapidly changing signals.

Part Description

The PCIE-1843/PCIE-1843L series is an analog input PCIe data acquisition solution for desktop and industrial computer systems. Depending on the model, the card provides either eight or four simultaneous analog input channels.

Key capabilities include:

• Up to 20 MS/s sampling performance
• 14-bit analog-to-digital conversion resolution
• Four or eight simultaneous analog input channels
• Configurable analog input ranges
• Digital and analog trigger support
• Onboard FIFO memory for more reliable high-speed data capture
• PCI Express interface for installation in compatible host computers
• Support for synchronized, multichannel signal acquisition

The combination of simultaneous sampling and onboard buffering makes these cards suitable for observing signals where timing relationships between channels are important. Configurable input ranges allow the acquisition hardware to be adapted to different sensor outputs, test signals, and measurement conditions.
