20.309:DAQ System

Each lab PC is equipped with a PCI-MIO-16E-1 data acquisition (DAQ) card. (National Instruments renamed the PCI-MIO-16E-1 to PCI6070E.)

The PCI-MIO-16E-1 is a PCI card that has a single, 12-bit analog to digital converter with a maximum sample rate of 1.25 MHz. A multiplexer selects from among 16 single-ended or 8 differentail input signals. In addition, the card includes an instrumentation amplifier with a programmable gain of 0.5 to 100. The card also supports two 12 bit analog output channels, 8 digital input and output lines, and two 24-bit counter/timers with a maximum clock rate of 20 MHz.

A 10 meter cable runs from the DAQ card to a BNC-2090 signal breakout box. The BNC-2090 provides BNC type connectors for each of the DAQ board’s analog inputs and outputs.
