© National Instruments Corporation 1-1 AT-MIO-16 User ManualChapter 1IntroductionThis chapter describes the AT-MIO-16; lists the contents of your AT-MIO-16 kit; describes theoptional software and optional equipment; and explains how to unpack the AT-MIO-16.About the AT-MIO-16Congratulations on your purchase of the National Instruments AT-MIO-16. The AT-MIO-16 is ahigh-performance, software-configurable 12-bit DAQ board for laboratory, test andmeasurement, and data acquisition and control applications. The board performs high-accuracymeasurements with high-speed settling to 12 bits, noise as low as 0.1 LSBrms, and a typicalDNL of ±0.5 LSB. Because of its FIFOs and dual-channel DMA, the AT-MIO-16 can achievehigh performance, even when used in environments that may have long interrupt latencies suchas Windows.A common problem with DAQ boards is that you cannot easily synchronize severalmeasurement functions to a common trigger or timing event. The AT-MIO-16 has the Real-Time System Integration (RTSI) bus to solve this problem. The RTSIbus consists of our customRTSI bus interface chip and a ribbon cable to route timing and trigger signals between severalfunctions on one or DAQ boards in your PC.The AT-MIO-16 can interface to the Signal Conditioning eXtensions for Instrumentation (SCXI)system so that you can acquire over 3,000 analog signals from thermocouples, RTDs, straingauges, voltage sources, and current sources. You can also acquire or generate digital signals forcommunication and control. SCXI is the instrumentation front-end for plug-in DAQ boards.What You Need to Get StartedTwo versions of the AT-MIO-16 are available–one version for each of two gain ranges. TheAT-MIO-16L (L stands for low-level signals) has software-programmable gain settings of 1, 10,100, and 500 for low-level analog input signals. The AT-MIO-16H (H stands for high-levelsignals) has software-programmable gain settings of 1, 2, 4, and 8 for high-level analog inputsignals. The AT-MIO-16(L/H)-9 contains an ADC with a 9 μs conversion time. TheAT-MIO-16(L/H)-9 is capable of data acquisition rates of up to 100 kHz.To set up and use your AT-MIO-16 board, you will need the following:An AT-MIO-16 boardAT-MIO-16 User Manual
