Table 3.1 lists the recommended connection methods for floating-ground signal sources and... -
Page 20: Floating Grounded Signal Source
Non-grounded reference single-ended input （NRSE） 3.3. 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. Common floating grounded signal sources are transformers, thermocouples, battery equipment, optical isolators, and isolation amplifier output. An instrument or device with isolated output is a floating-ground signal source. - Page 21 Figure 3.2 differential input mode for direct connection However, for a floating signal source with large internal resistance, the above connection will lead to the imbalance of differential signal, and the common-mode noise will be coupled to the signal of AI+ while not to AI-, so that the common-mode noise will appear in the measured results. Therefore, for such a signal source, you can use a bias resistor approximately 100 times the internal resistance of the signal source to connect to AI- and AI-GND ports, as shown in Figure 3.3.

If the AC coupled float signal source has a smaller internal resistance, the AI+ and AI-GND connection resistance values should be generally set as 100kΩ... -
Page 23: Grounded Signal Source
The length of the cable connecting signals to the acquisition device is lower than 3 meters If the signal does not meet the above conditions, it is recommended to use a differential mode connection to ensure better signal integrity. In single-ended mode, the electrostatic noise and electromagnetic noise of the coupled input signal connection are more than that in differential mode. -
Page 24: Use A Non-Grounded Reference Single-Ended Mode (Nrse) Connection
The cable connecting the signal to the acquisition device exceeds 3 meters The input signal requires a separate reference location or a return signal There is obvious noise in the environment of the signal wire Differential connection mode can reduce noise interference and improve the common-mode suppression of the acquisition device. -
