Page 19: Floating Grounded Signal Source
4.5. 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 isolate, and isolation amplifier output. An instrument or device with isolated output is a floating-ground signal source. - Page 20 Differential input mode with single bias resistor For a floating signal source with a large internal resistance, you can use the differential input mode with two bias resistors. 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.

Page 21: Non-Grounded Reference Single-Ended Mode (Nrse) Connection
⚫ Non-grounded reference single-ended mode (NRSE) connection When both the following conditions are true, you can connect the float signal using a non-grounded reference single-end mode: ◼ The input signal voltage is higher than 1V ◼ 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. -
Page 22: Grounded Signal Source
4.6. Grounded Signal Source The grounded signal source is a signal source connected to the building ground. If the computer is connected to the same power supply as the signal source, the source is already connected to a common ground point relative to the device. Instruments and equipment connected to the building power supply system while with non-isolated outputs belong to this type of signal source. -
