Floating grounded signal source A floating grounded signal source is not connected in any way to the building ground system but, it has an isolated ground-reference point. - Page 22 Differential connection mode can reduce noise interference and improve the common-mode suppression ability of acquisition device. 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.
- Page 23 For a floating signal source with a large internal resistance, you can use the differential input mode with two bias resistors, as shown in Figure 3.4. The fully balanced bias resistor connection in this way can provide a slightly better noise suppression, but it can reduce the load on the signal source and result in gain errors.
