Connecting Signals to the NI DAQPad-6015 BNC
Analog Input
You can use each analog input BNC connector for one differential signal or
two single-ended signals.
Differential Signals
To connect differential signals, determine the type of signal source you are
using: a floating signal source or a ground-referenced signal source. Refer
to the
Differential Connection Considerations and Connecting Analog
Input Signals
sections of Chapter 2, Analog Input, for more information on
connecting analog input signals and differential connection considerations.
To measure a floating signal source, move the switch to the FS position. To
measure a ground-referenced signal source, move the switch to the GS
position. Figure A-7 shows the source type switch locations on the front
panel of the BNC DAQPads.
Figure A-7. BNC DAQPads Front Panel
Figure A-8 shows the analog input circuitry on BNC DAQPads. When the
switch is in the FS position, AI x – is grounded through a 0.1 µF capacitor
in parallel with a 5 kΩ resistor.
