Chapter 3 Hardware Overview National Instruments Corporation 3-7 AT-MIO/AI E Series User Manual programmed on a per channel basis for multimode scanning. For example, you can configure the circuitry to scan 12 channels—four differentially configured channels and eight single-ended channels.
Chapter 3 Hardware Overview AT-MIO/AI E Series User Manual 3-8 National Instruments Corporation You can program polarity and range settings on a per channel basis so that you can configure each input channel uniquely.
Chapter 3 Hardware Overview National Instruments Corporation 3-9 AT-MIO/AI E Series User Manual ♦ AT-MIO-16XE-10, AT-AI-16XE-10, AT-MIO-16XE-50 These boards have two input polarities—unipolar and bipolar. Unipolar input means that the input voltage range is between 0 and V ref , where V ref is a positive reference voltage.
Chapter 3 Hardware Overview AT-MIO/AI E Series User Manual 3-10 National Instruments Corporation Considerations for Selecting Input Ranges Which input polarity and range you select depends on the expected range of the incoming signal. A large input range can accommodate a large signal variation but reduces the voltage resolution.
Chapter 3 Hardware Overview National Instruments Corporation 3-11 AT-MIO/AI E Series User Manual Dither When you enable dither, you add approximately 0.
Chapter 3 Hardware Overview AT-MIO/AI E Series User Manual 3-12 National Instruments Corporation Figure 3-7. Dither You cannot disable dither on the AT-MIO-16XE-10, AT-AI-16XE-10, or AT-MIO-16XE-50. This is because the resolution of the ADC is so fine that the ADC and the PGIA inherently produce almost 0.
Chapter 3 Hardware Overview National Instruments Corporation 3-13 AT-MIO/AI E Series User Manual constant and source impedances are low. Refer to Appendix A, Specifications , for a complete listing of settling times for each of the AT E Series boards.
Chapter 3 Hardware Overview AT-MIO/AI E Series User Manual 3-14 National Instruments Corporation Analog Output ♦ AT-MIO-16E-1, AT-MIO-16E-2, AT-MIO-64E-3, AT-MIO-16E-10, AT-MIO-16DE-10 The AT E Series boards supply two channels of analog output voltage at the I/O connector.
Chapter 3 Hardware Overview National Instruments Corporation 3-15 AT-MIO/AI E Series User Manual Selecting a bipolar range for a particular DAC means that any data written to that DAC will be interpreted as two’s complement format. In two’s complement mode, data values written to the analog output channel can be either positive or negative.
Chapter 3 Hardware Overview AT-MIO/AI E Series User Manual 3-16 National Instruments Corporation shown in Figure 3-8. The trigger-level range for the direct analog channel is ± 10 V in 78 mV steps for the AT-MIO-16E-1, AT-MIO-16E-2, and AT-MIO-64E-3, and ± 10 V in 4.
