3. Analog Input（AI） This chapter describes measuring the relevant content of analog input signals on PCI-2252/2253 series data acquisition devices. AI here is short for Analog Input. 3.1. Signal connection methods The AI acquisition connection mode of PCI-2252/2253 data acquisition device supports grounding reference single-ended input (RSE) and differential input (DIFF).
Page 25: Floating Grounded Signal Source
For a floating signal source with less than 100ΩF internal resistance, you can directly connect the negative end of the signal to AI- and AI-GND ports and connect the positive end of the signal to AI+ ports, as shown below in figure 3.2. PCI-2252/2253 The internal resistance is less than AI-GND 100Ω...
Page 26 AI- and AI-GND ports, as shown in Figure 3.3. This can make the differential signal close to equilibrium, hence couple the same amount of noise at both ends of the signal to enable better common-mode noise suppression. PCI-2252/2253 R≈100*Internal resistance of signal...
