Page 17: Signal Connection And Pin Assignment
Signal Connection and Pin Assignment 2.3.1 Analog Input Connection An analog input channel measures the voltage or current of the external sensor or source, converts the value into a digital form of data by an analog-to-digital converter (ADC), and passes it through a galvanic isolator to the internal circuit. Figure 2.2 shows the analog input signal connection. -
Page 18: Analog Output Connection
There is only one ADC in the device. An analog multiplexer selects one of the analog input channels at a time to be measured by the ADC. Therefore, the sample rate of the ADC is shared by all enabled channels. Refer to Appendix A Specifications for the sample rate supported. -

Page 22: Function Details
Function Details The iDAQ system relys on the chassis module as a platform to bring all the signals together in order to achieve functions including synchronization, data streaming, and timing control. This chapter describes all the functions that the iDAQ system provides and how they work. - Page 23 Figure 3.2 Buffered analog input acquisition. The start and stop mechanism of the data acquisition are controlled by the start trig- ger and stop trigger respectively. When configuration is completed, the acquisition engine of the iDAQ chassis is at standby state. After receiving a start trigger, acquisi- tion becomes active and each rising edge of the sample clock acquires one analog input sample.

Figure 3.4 Start and stop of the analog input acquisition with delay. Buffered analog input acquisition has several advantages over instant analog input acquisition: The start and stop time of acquisition (or duration of the acquisition) can be pre- cisely controlled by hardware trigger signals. -
Page 25: Analog Multiplexer
3.2.5 Analog Multiplexer The analog multiplexer routes one of the analog input channels at a time (one for sin- gle-ended configuration, and two for differential configuration) to the PGIA and ADC to be measured. This mechanism is called channel scanning. It realizes multiple channel measurement using only one ADC at a cost of sharing ADC sample rate among all scanned channels. - Page 26 Figure 3.7 Buffered analog output waveform generation The start and stop of the generation are controlled by the start trigger and stop trig- ger, respectively. When configuration is completed, the acquisition engine of the iDAQ chassis is at standby state. After receiving a start trigger, generation becomes active and each rising edge of the sample clock converts one analog output sample.

Buffered analog output waveform generation has several advantages over static ana- log output update: The start and stop time of generation (or duration of the generation) can be pre- cisely controlled by hardware trigger signals. DAC conversion rate is configurable, and update rate can be much higher by ... -
