Analog Input You can connect analog input signals to the NI USB-6008/6009 through the I/O connector. Refer to Table 6 for more information about connecting analog input signals. Analog Input Circuitry Figure 7 illustrates the analog input circuitry of the NI USB-6008/6009. +2.5 VREF 30.9 kΩ MUX PGA ADC AI FIFO 127 kΩ AI 39.2 kΩ Input Range Selection Figure 7. Analog Input Circuitry MUX The NI USB-6008/6009 has one analog-to-digital converter (ADC).
AI FIFO The NI USB-6008/6009 can perform both single and multiple A/D conversions of a fixed or infinite number of samples. A first-in-first-out (FIFO) buffer holds data during AI acquisitions to ensure that no data is lost. Analog Input Modes You can configure the AI channels on the NI USB-6008/6009 to take single-ended or differential measurements. Refer to Table 6 for more information about I/O connections for single-ended or differential measurements.
